public final class ArrayView<E>
extends AbstractSimpleArrayCollection<E>
implements XGettingList<E>
Immutable implementation of extended collection type XGettingList.

For mutable extended lists (implementors of XSettingList, XList), see FixedList, LimitList, BulkList.

As instances of this class are completely immutable after creation, this list is automatically thread-safe.

Also note that by being an extended collection, this implementation offers various functional and batch procedures to maximize internal iteration potential, eliminating the need to use the ill-conceived external iteration Iterator paradigm.

    • setArray

      public ArrayView<E> setArray​(E[] array)

    • internalGetStorageArray

      protected E[] internalGetStorageArray()
      Description copied from class: AbstractSimpleArrayCollection
      This is an internal shortcut method to provide fast access to the various array-backed list implementations' storage arrays.
      The purpose of this method is to allow access to the array only for read-only procedures, never for modifying accesses.

      The returned array is expected to contain the elements of the list in simple order from index 0 on to index (size - 1), so for example an array-backed ring list (queue) can NOT (reasonably) extend this class.

      Specified by:
      internalGetStorageArray in class AbstractSimpleArrayCollection<E>
      Returns:
      the storage array used by the list, containing all elements in straight order.

    • internalSize

      protected int internalSize()
      Specified by:
      internalSize in class AbstractSimpleArrayCollection<E>

    • internalGetSectionIndices

      protected int[] internalGetSectionIndices()
      Description copied from class: AbstractSectionedArrayCollection
      Defines the array sections in which the collection's elements are organized by one or more pairs of indices in the order corresponding to the collection's logical order of its contained elements.

      Examples:
      The trivial example would be {0,size} in case of standard sized array collections.
      An example for actual sectioning would be {i,array.length - 1, 0,i - 1} in case of a ring buffer list comprised of two sections: one ranging from index i to array.length - 1 (with the oldest element located at i) and one ranging from 0 to i - 1 (with the newest element located at i - 1).

      Specified by:
      internalGetSectionIndices in class AbstractSectionedArrayCollection<E>
      Returns:
      a list of index pairs defining all sections of the storage array in logical order.

    • copy

      public ArrayView<E> copy()
      Description copied from interface: XGettingSequence
      Creates a true copy of this list which references the same elements in the same order as this list does at the time the method is called. The elements themselves are NOT copied (no deep copying).
      The type of the returned list is the same as of this list if possible (i.e.: a SubList can not meaningful return a true copy that references its elements but still is a SubList)
      Specified by:
      copy in interface Copyable
      Specified by:
      copy in interface XGettingBag<E>
      Specified by:
      copy in interface XGettingCollection<E>
      Specified by:
      copy in interface XGettingList<E>
      Specified by:
      copy in interface XGettingSequence<E>
      Returns:
      a copy of this list

    • immure

      public XImmutableList<E> immure()
      Description copied from interface: XGettingList
      Provides an instance of an immutable collection type with equal behavior and data as this instance.

      If this instance already is of an immutable collection type, it returns itself.

      Specified by:
      immure in interface XGettingBag<E>
      Specified by:
      immure in interface XGettingCollection<E>
      Specified by:
      immure in interface XGettingList<E>
      Specified by:
      immure in interface XGettingSequence<E>
      Returns:
      an immutable copy of this collection instance.

    • toReversed

      public ArrayView<E> toReversed()
      Description copied from interface: XGettingSequence
      Creates a new XGettingSequence with the reversed order of elements.

      This method creates a new collection and does not change the existing collection.

      Specified by:
      toReversed in interface XGettingList<E>
      Specified by:
      toReversed in interface XGettingSequence<E>
      Returns:
      New copy of the collection

    • toArray

      public E[] toArray​(Class<E> type)
      Description copied from interface: XGettingCollection
      Returns a typed array containing all of the elements in this collection.

      The returned array will be "safe" in that no references to it are maintained by this list. (In other words, this method must allocate a new array). The caller is thus free to modify the returned array.

      This method acts as bridge between MicroStream-based collections and Java-native-based APIs.

      Specified by:
      toArray in interface XGettingCollection<E>
      Parameters:
      type - the Class representing type E at runtime.
      Returns:
      a typed array containing all of the elements in this collection

    • iterate

      public <P extends Consumer<? super E>> P iterate​(P procedure)
      Description copied from interface: XIterable
      Executes the given procedure for each element of the XIterable until all elements have been processed or the action throws an exception. Unless otherwise specified by the implementing class, procedures are performed in the order of iteration (if an iteration order is specified). Exceptions thrown by the procedure are relayed to the caller.
      Should be identical to Iterable.forEach(Consumer).
      Specified by:
      iterate in interface XIterable<E>
      Type Parameters:
      P - type of procedure
      Parameters:

      Description copied from interface: XJoinable
      Iterates over all elements of the collections and calls the joiner with each element and the aggregate.
      Specified by:
      join in interface XGettingCollection<E>
      Specified by:
      join in interface XJoinable<E>
      Type Parameters:
      A - type of aggregate
      Parameters:
      joiner - is the actual function to do the joining
      aggregate - where to join into
      Returns:
      the joined aggregate

    • iterateIndexed

      public final <P extends IndexedAcceptor<? super E>> P iterateIndexed​(P procedure)
      Description copied from interface: XIndexIterable
      Iterates over elements with the IndexedAcceptor to use not only the element itself but also its coherent index.
      Specified by:
      iterateIndexed in interface XIndexIterable<E>
      Type Parameters:
      P - type of procedure
      Parameters:
      procedure - which is executed when iterating
      Returns:
      Given procedure

    • count

      public long count​(E element)
      Description copied from interface: XGettingCollection
      Count how many times this element matches another element in the collection using the Equalator.
      Specified by:
      count in interface XGettingCollection<E>
      Parameters:
      element - to count
      Returns:
      Amount of matches

    • countBy

      public long countBy​(Predicate<? super E> predicate)
      Description copied from interface: XGettingCollection
      Count how many matches are found using the given predicate on each element of the collection.
      Specified by:
      countBy in interface XGettingCollection<E>
      Parameters:
      predicate - defines which elements are counted and which are not
      Returns:
      Amount of matches

    • indexOf

      public long indexOf​(E element)
      Specified by:
      indexOf in interface XGettingSequence<E>

    • indexBy

      public long indexBy​(Predicate<? super E> predicate)
      Description copied from interface: XGettingSequence
      Iterates forwards through the collection and returns the index of the first element that the passed {link Predicate} applies to immediately.
      Stops iterating on the first element that the predicate applies to.

      Basically the opposite of XGettingSequence.lastIndexBy(Predicate)

      Specified by:
      indexBy in interface XGettingSequence<E>
      Parameters:
      predicate - to define a valid element
      Returns:
      The index of the first positively tested element.

    • lastIndexOf

      public long lastIndexOf​(E element)
      Specified by:
      lastIndexOf in interface XGettingSequence<E>

    • lastIndexBy

      public long lastIndexBy​(Predicate<? super E> predicate)
      Description copied from interface: XGettingSequence
      Iterates backwards through the collection and returns the index of the last element that the passed Predicate applies to immediately.
      Stops iterating on the first element that the predicate applies to.

      Basically the opposite of XGettingSequence.indexBy(Predicate).
      Similar but not the same as XGettingSequence.scan(Predicate), since scan iterates through all elements.

      Specified by:
      lastIndexBy in interface XGettingSequence<E>
      Parameters:
      predicate - to define a valid element
      Returns:
      the index of the last positively tested element.

    • maxIndex

      public long maxIndex​(Comparator<? super E> comparator)
      Specified by:
      maxIndex in interface XGettingSequence<E>

    • minIndex

      public long minIndex​(Comparator<? super E> comparator)
      Specified by:
      minIndex in interface XGettingSequence<E>

    • scan

      public long scan​(Predicate<? super E> predicate)
      Description copied from interface: XGettingSequence
      Iterates through the collection and returns the index of the last element that the passed Predicate applied to ("scanning").

      In order to find the last element, this method must iterate over all elements of the collection (opposed to XGettingSequence.indexBy(Predicate) and XGettingSequence.lastIndexBy(Predicate)).

      Iteration can be safely canceled with a ThrowBreak (X.BREAK)

      Specified by:
      scan in interface XGettingSequence<E>
      Parameters:
      predicate - to define a valid element
      Returns:
      the index of the last positively tested element.

    • get

      public E get()
      Description copied from interface: XGettingSequence
      Gets the first element in the collection. This is a parameterless alias for at(0).

      XGettingSequence.first() is an alias for this method.

      Specified by:
      get in interface XGettingCollection<E>
      Specified by:
      get in interface XGettingSequence<E>
      Returns:
      the first element.
      See Also:
      XGettingSequence.at(long), XGettingSequence.first(), XGettingSequence.last()

    • first

      public E first()
      Description copied from interface: XGettingSequence
      Gets first element or throws IndexOutOfBoundsException if the collection is empty.

      Is an alias for XGettingSequence.get().

      Specified by:
      first in interface XGettingSequence<E>
      Returns:
      First element

    • last

      public E last()
      Description copied from interface: XGettingSequence
      Gets last element or throws IndexOutOfBoundsException if the collection is empty.
      Specified by:
      last in interface XGettingSequence<E>
      Returns:
      Last element

    • poll

      public E poll()
      Description copied from interface: XGettingSequence
      Gets first element or null if the collection is empty.
      Specified by:
      poll in interface XGettingSequence<E>
      Returns:
      First element or null

    • peek

      public E peek()
      Description copied from interface: XGettingSequence
      Gets last element or null if the collection is empty.
      This behaves like peeking on a stack without pop.
      Specified by:
      peek in interface XGettingSequence<E>
      Returns:
      Last element or null

    • seek

      public E seek​(E sample)
      Description copied from interface: XGettingCollection
      Returns the first contained element matching the passed sample as defined by the collection's equality logic or null, if no fitting element is contained. (For collections using referential equality, this method is basically just a variation of XGettingCollection.contains(Object) with a different return type. For collections with data-dependant equality, the returned element might be the same as the passed one or a data-wise equal one, depending on the content of the collection)
      Specified by:
      seek in interface XGettingCollection<E>
      Parameters:
      sample - to seek in the collection
      Returns:
      the first contained element matching the passed sample

    • search

      public E search​(Predicate<? super E> predicate)
      Description copied from interface: XGettingCollection
      Returns the first contained element matching the passed predicate.
      Specified by:
      search in interface XGettingCollection<E>
      Parameters:
      predicate - defines which element is searched
      Returns:
      Matching element

    • max

      public E max​(Comparator<? super E> comparator)
      Specified by:
      max in interface XGettingCollection<E>

    • min

      public E min​(Comparator<? super E> comparator)
      Specified by:
      min in interface XGettingCollection<E>

    • hasVolatileElements

      public boolean hasVolatileElements()
      Description copied from interface: ExtendedCollection
      Tells if this collection contains volatile elements.
      An element is volatile, if it can become no longer reachable by the collection without being removed from the collection. Examples are WeakReference of SoftReference or implementations of collection entries that remove the element contained in an entry by some means outside the collection.
      Note that WeakReference instances that are added to a a simple (non-volatile) implementation of a collection do not make the collection volatile, as the elements themselves (the reference instances) are still strongly referenced.
      Specified by:
      hasVolatileElements in interface ExtendedCollection<E>
      Specified by:
      hasVolatileElements in interface XGettingCollection<E>
      Returns:
      true if the collection contains volatile elements.

    • nullAllowed

      public boolean nullAllowed()
      Description copied from interface: ExtendedCollection

      true if null is allowed inside the collection; false if not

    • isSorted

      public boolean isSorted​(Comparator<? super E> comparator)
      Description copied from interface: XGettingSequence
      Tests if the collection is sorted according to the given comparator.
      Specified by:
      isSorted in interface XGettingSequence<E>
      Parameters:
      comparator - defines if elements are sorted
      Returns:
      true if it sorted, false if not

    • containsSearched

      public boolean containsSearched​(Predicate<? super E> predicate)
      Specified by:
      containsSearched in interface XGettingCollection<E>

    • applies

      public boolean applies​(Predicate<? super E> predicate)
      Description copied from interface: XGettingCollection
      Tests each element of the collection on the given predicate.
      Specified by:
      applies in interface XGettingCollection<E>
      Parameters:
      predicate - that's tested on each element.
      Returns:
      If all elements test successfully, true is returned. Otherwise (if at least one test has failed), false is returned.

    • nullContained

      public boolean nullContained()
      Specified by:
      nullContained in interface XGettingCollection<E>

    • containsId

      public boolean containsId​(E element)
      Description copied from interface: XGettingCollection
      Special version of contains() that guarantees to use identity comparison (" == ") when searching for the given element regardless of the collection's internal logic.
      This method has the same behavior as XGettingCollection.containsSearched(Predicate) with a Predicate implementation that checks for object identity. The only difference is a performance and usability advantage
      Specified by:
      containsId in interface XGettingCollection<E>
      Parameters:
      element - the element to be searched in the collection by identity.
      Returns:
      whether this collection contains exactly the given element.

    • contains

      public boolean contains​(E element)
      Description copied from interface: XGettingCollection
      Checks if the given element is contained in the collection.
      In contrast to the XGettingCollection.containsId(Object) method, this method uses the internal Equalator defined by the collection itself.
      Specified by:
      contains in interface XGettingCollection<E>
      Parameters:
      element - to be searched in the collection
      Returns:
      Whether this collection contains the given element as specified by the Equalator.

    • containsAll

      public boolean containsAll​(XGettingCollection<? extends E> elements)
      Specified by:
      containsAll in interface XGettingCollection<E>
      Parameters:
      elements - to be searched in the collection.
      Returns:
      Whether this collection contains all given elements as specified by the Equalator.

    • equals

      public boolean equals​(XGettingCollection<? extends E> samples, Equalator<? super E> equalator)
      Specified by:
      equals in interface XGettingCollection<E>
      Parameters:
      samples - is the collection which is checked for equality
      equalator - is used to check the equality of the collections
      Returns:
      true if the passed collection is of the same type as this collection and this.equalsContent(list, equalator) yields true

    • equalsContent

      public boolean equalsContent​(XGettingCollection<? extends E> samples, Equalator<? super E> equalator)
      Description copied from interface: XGettingCollection
      Returns true if all elements of this list and the passed list are sequentially equal as defined by the passed equalator.

      Note that for colletion types that don't have a defined order of elements, this method is hardly usable (as is XGettingCollection.equals(Object) for them as defined in Collection). The core problem of comparing collections that have no defined order is that they aren't really reliably comparable to any other collection.

      Specified by:
      equalsContent in interface XGettingCollection<E>
      Parameters:
      samples - is the collection which is checked for equality
      equalator - the equalator to use to determine the equality of each element
      Returns:
      true if this list is equal to the passed list, false otherwise

    • intersect

      public <C extends Consumer<? super E>> C intersect​(XGettingCollection<? extends E> samples, Equalator<? super E> equalator, C target)
      Description copied from interface: XGettingCollection
      Tests equality between each element of the two lists and calls Consumer.accept(Object) on the target Consumer for the equal elements.
      Therefore it effectively creates a mathematical intersection between the two collections.

      Since all MicroStream Collections implement the Consumer interface, new collections can be used as target.

      Example:

       BulkList<Integer> collection1 = BulkList.New(1,2,3);
 BulkList<Integer> collection2 = BulkList.New(2,3,4);
 BulkList<Integer> intersection = collection1.intersect(collection2, Equalator.identity(), BulkList.New());
      Results in intersection containing 2 and 3.
      Specified by:
      intersect in interface XGettingCollection<E>
      Type Parameters:
      C - type of the target
      Parameters:
      samples - collection to intersect with.
      equalator - which is used for the equal-tests.
      target - on which the Consumer.accept(Object) is called for equal elements.
      Returns:
      Given target

    • except

      public <C extends Consumer<? super E>> C except​(XGettingCollection<? extends E> samples, Equalator<? super E> equalator, C target)
      Description copied from interface: XGettingCollection
      Calls Consumer.accept(Object) on the target Consumer for each element of this collection that is not contained in the other collection (through the given equalator).

      Since all MicroStream Collections implement the Consumer interface, new collections can be used as target.

      Example:

       BulkList<Integer> collection1 = BulkList.New(1,2,3);
 BulkList<Integer> collection2 = BulkList.New(2,3,4);
 BulkList<Integer> exceptCollection = collection1.except(collection2, Equalator.identity(), BulkList.New());
      Results in exceptCollection containing 1.
      Specified by:
      except in interface XGettingCollection<E>
      Type Parameters:
      C - type of the target
      Parameters:
      samples - collection whose elements are excluded from the target.
      equalator - which is used for the equal-tests.
      target - on which the Consumer.accept(Object) is called for elements not contained in the other collection.
      Returns:
      Given target

    • union

      public <C extends Consumer<? super E>> C union​(XGettingCollection<? extends E> samples, Equalator<? super E> equalator, C target)
      Description copied from interface: XGettingCollection
      Calls Consumer.accept(Object) on the target Consumer for all the elements of this collection. And calls it for all elements of the other collection, that are not already in this collection (defined by the given Equalator)
      Therefore it effectively creates a mathematical union between the two collections.

      Since all MicroStream Collections implement the Consumer interface, new collections can be used as target.

      Example:

       BulkList<Integer> collection1 = BulkList.New(1,2,3);
 BulkList<Integer> collection2 = BulkList.New(2,3,4);
 BulkList<Integer> union = collection1.union(collection2, Equalator.identity(), BulkList.New());
      Results in union containing 1, 2, 3 and 4.
      Specified by:
      union in interface XGettingCollection<E>
      Type Parameters:
      C - type of the target
      Parameters:
      samples - collection to build a union with.
      equalator - which is used for the equal-tests.
      target - on which the Consumer.accept(Object) is called for all unified elements.

      public <C extends Consumer<? super E>> C copyTo​(C target)
      Description copied from interface: XGettingCollection
      Calls Consumer.accept(Object) on the target Consumer for all the elements of this collection.

      Since all MicroStream Collections implement the Consumer interface, new collections can be used as target.

      Example:

       BulkList<Integer> collection1 = BulkList.New(1,2,3);
 BulkList<Integer> copiedCollection = collection1.copyTo(BulkList.New());
      Results in copiedCollection containing 1, 2 and 3.

      copyTo in interface XGettingCollection<E>
      Type Parameters:
      C - type of the target
      Parameters:
      target - on which the Consumer.accept(Object) is called for all elements of this collection.
      Returns:
      Given target

      Description copied from interface: XGettingCollection
      Calls Consumer.accept(Object) on the target Consumer for all the elements of this collection which test true on the given predicate.

      Since all MicroStream Collections implement the Consumer interface, new collections can be used as target.

      Example:

       BulkList<Integer> collection1 = BulkList.New(1,2,3);

    • maximumCapacity

      public long maximumCapacity()
      Description copied from interface: CapacityCarrying
      Returns the maximum amount of elements this carrier instance can contain.
      The actual value may be depend on the configuration of the concrete instance or may depend only on the implementation of the carrier (meaning it is constant for all instances of the implementation, e.g. Integer.MAX_VALUE)
      Specified by:
      maximumCapacity in interface CapacityCarrying
      Returns:
      the maximum amount of elements this carrier instance can contain.

    • isFull

      public boolean isFull()

    • view

      public ArrayView<E> view()
      Description copied from interface: XGettingCollection
      Creates a view of this collection and returns it. It is a read-only collection, which wraps around this collection and only allows read methods.

      A view is different from immutable collection (XGettingCollection.immure()) in the way, that changes in this collection are still affecting the view. The immutable collection on the other hand has no reference to this collection and changes therefore do not affect the immutable collection.

      Specified by:
      view in interface XGettingBag<E>
      Specified by:
      view in interface XGettingCollection<E>
      Specified by:
      view in interface XGettingList<E>
      Specified by:
      view in interface XGettingSequence<E>
      Returns:
      new read-only collection to view this collection

    • view

      public SubListView<E> view​(long fromIndex, long toIndex)
      Description copied from interface: XGettingSequence
      Creates a sub-view of this collection and returns it. It is a read-only collection, which wraps around this collection and only allows read methods.
      The view is limited to a range from the lowIndex to the highIndex.

      A view is different from immutable collection (XGettingCollection.immure()) in the way, that changes in this collection are still affecting the view. The immutable collection on the other hand has no reference to this collection and changes therefore do not affect the immutable collection.

      Specified by:
      view in interface XGettingList<E>
      Specified by:
      view in interface XGettingSequence<E>
      Parameters:
      fromIndex - defines lower boundary for the view of the collection.
      toIndex - defines higher boundary for the view of the collection.
      Returns:
      new read-only collection to view a range of elements in this collection

    • range

    • toString

      public String toString()
      Overrides:
      toString in class Object

    • toArray

      public Object[] toArray()
      Description copied from interface: XGettingCollection
      Returns an array containing all of the elements in this collection.

      The returned array will be "safe" in that no references to it are maintained by this list. (In other words, this method must allocate a new array). The caller is thus free to modify the returned array.

      This method acts as bridge between MicroStream-based collections and Java-native-based APIs.

      Specified by:
      toArray in interface XGettingCollection<E>
      Returns:
      an array containing all of the elements in this collection

    • equals

      @Deprecated public boolean equals​(Object o)
      Deprecated.
      Description copied from interface: XGettingCollection
      Performs an equality comparison according to the specification in Collection.

      Note that it is this interface's author opinion that the whole concept of equals() in standard Java, especially in the collection implementations, is flawed.
      The reason is because all different kinds of comparison types that actually depend on the situation have to be mixed up in a harcoded fashion in one method, from identity comparison over data indentity comparison to content comparison.
      In order to get the right behavior in every situation, one has to distinct between different types of equality

      This means several things:
      1.) You can't just say for example an ArrayList is the "same" as a LinkedList just because they contain the same content.
      There are different implementations for a good reason, so you have to distinct them when comparing. There are simple code examples which create massive misbehavior that will catastrophically ruin the runtime behavior of a programm due to this error in Java / JDK / Sun / whatever.
      2.) You can't always determine equality of two collections by determining equality of each element as Collection defines it.

      As a conclusion: don't use this method!
      Be clear what type of comparison you really need, then use one of the following methods and proper comparators:
      XGettingCollection.equals(XGettingCollection, Equalator)
      XGettingCollection.equalsContent(XGettingCollection, Equalator)

      Specified by:
      equals in interface XGettingCollection<E>
      Overrides:
      equals in class Object
      Parameters:
      o - the reference object with which to compare.
