    • contains

      public final 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 final 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.

    • containsId

      public final 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.

      public final <C extends Consumer<? super E>> C filterTo​(C target, Predicate<? super E> predicate)
      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);
      BulkList<Integer> filteredCollection = collection1.filterTo(BulkList.New(), e-> e % 2 == 0);

      filterTo in interface XGettingCollection<E>
      Parameters:
      target - on which the Consumer.accept(Object) is called for elements that test true.
      predicate - on which to test all elements.
      Returns:
      Given target

    • copyTo

      public final <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.

      Description copied from interface: XGettingCollection
      Calls Consumer.accept(Object) on the target Consumer for all the unique/distinct elements of this collection. This means the elements are not equal to each other.
      Uniqueness is defined by the given Equalator.

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

      Example:
      BulkList<Integer> collection1 = BulkList.New(1,2,2,3);
      BulkList<Integer> distinctCollection = collection1.distinct(BulkList.New(), Equalator.identity());

    • equals

      @Deprecated public final 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

    • equals

      public final 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 final 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

    • except

      public final <C extends Consumer<? super E>> C except​(XGettingCollection<? extends E> other, 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:
      other - 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

    • iterate

      public final <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>
      Specified by:
      iterate in interface XProcessingCollection<E>
      Type Parameters:

      Specified by:
      join in interface XGettingCollection<E>
      Specified by:
      join in interface XJoinable<E>
      Type Parameters:

    • hasVolatileElements

      public final 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.

    • intersect

      public final <C extends Consumer<? super E>> C intersect​(XGettingCollection<? extends E> other, 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>
      Parameters:
      other - 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

      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 final 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

    • optimize

      public final long optimize()
      Description copied from interface: OptimizableCollection
      Optimizes the internal storage of this collection and returns the storage size of the collection after the process is complete.
      Specified by:
      optimize in interface OptimizableCollection
      Specified by:
      optimize in interface XRemovingCollection<E>
      Returns:
      the storage size of the collection after the optimzation.

    • size

      size in interface Sized
      Specified by:
      size in interface XGettingCollection<E>

    • toArray

      public final 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

    • toArray

      public final 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>
      Returns:
      a typed array containing all of the elements in this collection

    • truncate

      public final void truncate()
      Description copied from interface: XRemovingCollection
      Clears (and reinitializes if needed) this collection in the fastest possible way, i.e. by allocating a new and empty internal storage of default capacity. The collection will be empty after calling this method.
      Specified by:
      truncate in interface Truncateable
      Specified by:
      truncate in interface XRemovingCollection<E>

    • union

      public final <C extends Consumer<? super E>> C union​(XGettingCollection<? extends E> other, 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>
      Parameters:
      other - 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.
      Returns:
      Given target

    • currentCapacity

      public final long currentCapacity()
      Description copied from interface: CapacityExtendable
      Returns the current amount of elements this instance can hold before a storage rebuild becomes necessary.

      For carrier implementations that don't have a concept of storage rebuilding (like linked list for example) this method returns the same value as CapacityCarrying.maximumCapacity().

      Specified by:
      currentCapacity in interface CapacityExtendable
      Returns:
      the current capacity of this instance before a rebuild is required.

    • maximumCapacity

      public final 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 final boolean isFull()
      Description copied from interface: CapacityCarrying
      Returns true if the current capacity cannot be increased any more.
      Specified by:
      isFull in interface CapacityCarrying

    • remainingCapacity

      public final long remainingCapacity()
      Description copied from interface: CapacityCarrying
      Returns the amount of elements this carrier instance can collect before reaching its maximimum capacity.
      Specified by:
      remainingCapacity in interface CapacityCarrying

    • nullAllowed

      public final boolean nullAllowed()
      Description copied from interface: ExtendedCollection
      Defines if null-elements are allowed inside the collection or not.
      Specified by:
      nullAllowed in interface ExtendedCollection<E>
      Returns:
      true if null is allowed inside the collection; false if not

    • nullContained

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

    • nullRemove

      Specified by:
      nullRemove in interface XRemovingCollection<E>

    • copy

      public final LockedCollection<E> copy()
      Description copied from interface: XGettingCollection
      Creates a true copy of this collection which references the same elements as this collection does at the time the method is called. The elements themselves are NOT copied (no deep copying).
      The type of the returned set is the same as of this list if possible.
      Specified by:
      copy in interface Copyable
      Specified by:
      copy in interface XAddGetCollection<E>
      Specified by:
      copy in interface XCollection<E>
      Specified by:
      copy in interface XGettingCollection<E>
      Specified by:
      copy in interface XPutGetCollection<E>
      Returns:
      a copy of this list

    • immure

      public final XImmutableCollection<E> immure()
      Description copied from interface: XGettingCollection
      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 XGettingCollection<E>
      Returns:
      an immutable copy of this collection instance.

    • view

      public final View<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 XGettingCollection<E>
      Returns:
      new read-only collection to view this collection

    • old

      public final LockedCollection.OldMutexCollection<E> old()
      Specified by:
      old in interface XGettingCollection<E>
