Method Summary

Modifier and Type	Method	Description
`boolean`	`applies(Predicate<? super KeyValue<K,V>> predicate)`	Tests each element of the collection on the given predicate.
`KeyValue<K,V>`	`at(long index)`
`boolean`	`contains(KeyValue<K,V> element)`	Checks if the given element is contained in the collection.
`boolean`	`containsAll(XGettingCollection<? extends KeyValue<K,V>> elements)`
`boolean`	`containsId(KeyValue<K,V> element)`	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.
`boolean`	`containsSearched(Predicate<? super KeyValue<K,V>> predicate)`
`EmptyTable<K,V>`	`copy()`	Creates a true copy of this collection which references the same elements as this collection does at the time the method is called.
`<T extends Consumer<? super KeyValue<K, V>>> T`	`copySelection(T target, long... indices)`	Iterates through all the elements of the given indices and calls the `Consumer.accept(Object)` on the target `Consumer`.
`<T extends Consumer<? super KeyValue<K, V>>> T`	`copyTo(T target)`	Calls `Consumer.accept(Object)` on the target `Consumer` for all the elements of this collection.
`long`	`count(KeyValue<K,V> element)`	Count how many times this element matches another element in the collection using the `Equalator`.
`long`	`countBy(Predicate<? super KeyValue<K,V>> predicate)`	Count how many matches are found using the given predicate on each element of the collection.
`<T extends Consumer<? super KeyValue<K, V>>> T`	`distinct(T target)`	Calls `Consumer.accept(Object)` on the target `Consumer` for all the unique/distinct elements of this collection.
`<T extends Consumer<? super KeyValue<K, V>>> T`	`distinct(T target, Equalator<? super KeyValue<K,V>> equalator)`	Calls `Consumer.accept(Object)` on the target `Consumer` for all the unique/distinct elements of this collection.
`Equalator<? super KeyValue<K,V>>`	`equality()`
`boolean`	`equals(XGettingCollection<? extends KeyValue<K,V>> samples, Equalator<? super KeyValue<K,V>> equalator)`
`boolean`	`equalsContent(XGettingCollection<? extends KeyValue<K,V>> samples, Equalator<? super KeyValue<K,V>> equalator)`	Returns `true` if all elements of this list and the passed list are sequentially equal as defined by the passed equalator.
`<T extends Consumer<? super KeyValue<K, V>>> T`	`except(XGettingCollection<? extends KeyValue<K,V>> other, Equalator<? super KeyValue<K,V>> equalator, T target)`	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).
`<T extends Consumer<? super KeyValue<K, V>>> T`	`filterTo(T target, Predicate<? super KeyValue<K,V>> predicate)`	Calls `Consumer.accept(Object)` on the target `Consumer` for all the elements of this collection which test `true` on the given predicate.
`KeyValue<K,V>`	`first()`	Gets first element or throws `IndexOutOfBoundsException` if the collection is empty.
`KeyValue<K,V>`	`get()`	Gets one element from the collection.
`V`	`get(K key)`
`boolean`	`hasVolatileElements()`	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.
`XImmutableTable<K,V>`	`immure()`	Provides an instance of an immutable collection type with equal behavior and data as this instance.
`long`	`indexBy(Predicate<? super KeyValue<K,V>> predicate)`	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.
`long`	`indexOf(KeyValue<K,V> element)`
`<T extends Consumer<? super KeyValue<K, V>>> T`	`intersect(XGettingCollection<? extends KeyValue<K,V>> other, Equalator<? super KeyValue<K,V>> equalator, T target)`	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.
`boolean`	`isEmpty()`
`boolean`	`isFull()`	Returns true if the current capacity cannot be increased any more.
`boolean`	`isSorted(Comparator<? super KeyValue<K,V>> comparator)`	Tests if the collection is sorted according to the given comparator.
`<P extends Consumer<? super KeyValue<K, V>>> P`	`iterate(P procedure)`	Executes the given procedure for each element of the `XIterable` until all elements have been processed or the action throws an exception.
`<P extends IndexedAcceptor<? super KeyValue<K, V>>> P`	`iterateIndexed(P procedure)`	Iterates over elements with the `IndexedAcceptor` to use not only the element itself but also its coherent index.

`KeyValue<K,V>`	`last()`	Gets last element or throws `IndexOutOfBoundsException` if the collection is empty.
`long`	`lastIndexBy(Predicate<? super KeyValue<K,V>> predicate)`	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.

`KeyValue<K,V>`	`lookup(K key)`
`KeyValue<K,V>`	`max(Comparator<? super KeyValue<K,V>> comparator)`
`long`	`maximumCapacity()`	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.
`long`	`maxIndex(Comparator<? super KeyValue<K,V>> comparator)`
`KeyValue<K,V>`	`min(Comparator<? super KeyValue<K,V>> comparator)`
`long`	`minIndex(Comparator<? super KeyValue<K,V>> comparator)`
`boolean`	`nullAllowed()`	Defines if null-elements are allowed inside the collection or not.
`boolean`	`nullContained()`
`boolean`	`nullKeyAllowed()`

  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)

  Returns:
  
  the maximum amount of elements this carrier instance can contain.

- 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<K>
  
  Specified by:
  
  hasVolatileElements in interface XGettingCollection<K>
  
  Returns:
  
  true if the collection contains volatile elements.
- 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<K>
  
  Returns:
  
  true if null is allowed inside the collection; false if not
- view
  
  public final EmptyTable<K,V> 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:

  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 XGettingEnum<K>
  
  Specified by:
  
  iterate in interface XGettingSet<K>
  
  Specified by:

  Type Parameters:
  
  P - type of procedure
  
  Parameters:
  
  procedure - The procedure to be performed for each element
  
  Returns:
  
  Given procedure
- get
  
  public KeyValue<K,V> get()
  
  Description copied from interface: XGettingCollection
  
  Gets one element from the collection. If the collection is not ordered XGettingSequence, then it is undefined which element is returned. If the collection is ordered, the element at index 0 is returned.
  
  Specified by:
  
  get in interface XGettingCollection<K>
  
  Specified by:
  
  get in interface XGettingSequence<K>
  
  Returns:

  Specified by:
  
  iterator in interface XGettingCollection<K>
- 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<K>
  
  Returns:
  
  an array containing all of the elements in this collection
- toArray
  
  public KeyValue<K,V>[] toArray(Class<KeyValue<K,V>> 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<K>
  
  Returns:
  
  a typed array containing all of the elements in this collection
- equality
  
  public Equalator<? super KeyValue<K,V>> equality()
  
  Specified by:
  
  equality in interface XGettingCollection<K>
- equals
  
  public boolean equals(XGettingCollection<? extends KeyValue<K,V>> samples, Equalator<? super KeyValue<K,V>> equalator)
  
  Specified by:
  
  equals in interface XGettingCollection<K>
  
  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 KeyValue<K,V>> samples, Equalator<? super KeyValue<K,V>> 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<K>
  
  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
- nullContained
  
  public boolean nullContained()
  
  Specified by:
  
  nullContained in interface XGettingCollection<K>
- containsId
  
  public boolean containsId(KeyValue<K,V> 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<K>
  
  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(KeyValue<K,V> 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<K>
  
  Parameters:
  
  element - to be searched in the collection
  
  Returns:
  
  Whether this collection contains the given element as specified by the Equalator.

  public boolean containsSearched(Predicate<? super KeyValue<K,V>> predicate)
  
  Specified by:
  
  containsSearched in interface XGettingCollection<K>
- containsAll
  
  public boolean containsAll(XGettingCollection<? extends KeyValue<K,V>> elements)
  
  Specified by:
  
  containsAll in interface XGettingCollection<K>
  
  Parameters:
  
  elements - to be searched in the collection.
  
  Returns:
  
  Whether this collection contains all given elements as specified by the Equalator.
- applies
  
  public boolean applies(Predicate<? super KeyValue<K,V>> predicate)
  
  Description copied from interface: XGettingCollection
  
  Tests each element of the collection on the given predicate.
  
  Specified by:
  
  applies in interface XGettingCollection<K>
  
  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.
- count
  
  public long count(KeyValue<K,V> 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<K>
  
  Parameters:
  
  element - to count
  
  Returns:

  Specified by:
  
  countBy in interface XGettingCollection<K>
  
  Parameters:
  
  predicate - defines which elements are counted and which are not
  
  Returns:
  
  Amount of matches
- search
  
  public KeyValue<K,V> search(Predicate<? super KeyValue<K,V>> predicate)
  
  Description copied from interface: XGettingCollection
  
  Returns the first contained element matching the passed predicate.

  public KeyValue<K,V> seek(KeyValue<K,V> 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)

- view
  
  public XGettingEnum<KeyValue<K,V>> view(long lowIndex, long highIndex)
  
  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:

- indexBy
  
  public long indexBy(Predicate<? super KeyValue<K,V>> 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<K>
  
  Parameters:
  
  predicate - to define a valid element
  
  Returns:

- lastIndexBy
  
  public long lastIndexBy(Predicate<? super KeyValue<K,V>> 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<K>
  
  Parameters:
  
  predicate - to define a valid element
  
  Returns:
  
  the index of the last positively tested element.

  public long scan(Predicate<? super KeyValue<K,V>> 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<K>
  
  Parameters:
  
  predicate - to define a valid element
  
  Returns:
