boolean	applies(Predicate<? super E> predicate)
E	at(long index)
boolean	contains(E element)
boolean	containsAll(XGettingCollection<? extends E> elements)
boolean	containsId(E 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 E> predicate)
SubListView<E>	copy()	Creates a true copy of this list which references th same elements in the same order as this list does at the time the method is called.
<C extends Consumer<? super E>> C	copySelection(C target, long... indices)
<C extends Consumer<? super E>> C	copyTo(C target)
long	count(E element)
long	countBy(Predicate<? super E> predicate)

<C extends Consumer<? super E>> C	distinct(C target, Equalator<? super E> equalator)
Equalator<? super E>	equality()
boolean	equals(XGettingCollection<? extends E> samples, Equalator<? super E> equalator)	Returns true if the passed collection is of the same type as this collection andthis.equalsContent(list, equalator) yields true.
boolean	equalsContent(XGettingCollection<? extends E> samples, Equalator<? super E> equalator)	Returns true if all elements of this list and the passed list are sequentially equal as defined by the passed equalator.

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 exactely the given element.

copyTo

public <C extends Consumer<? super E>> C copyTo(C target)

distinct

public <C extends Consumer<? super E>> C distinct(C target, Equalator<? super E> equalator)

Specified by:

distinct in interface XGettingCollection<E>

hasVolatileElements

public boolean hasVolatileElements()

Description copied from interface: XGettingCollection

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.

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>

search

public E search(Predicate<? super E> predicate)

Specified by:

search in interface XGettingCollection<E>

toArray

public E[] toArray(Class<E> type)

public final <P extends IndexedAcceptor<? super E>> P iterateIndexed(P procedure)

Specified by:

join

public final <A> A join(BiConsumer<? super E,? super A> joiner, A aggregate)

Specified by:

join in interface XGettingCollection<E>

Specified by:

join in interface XJoinable<E>

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>

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

Specified by:

old in interface XGettingCollection<E>

Specified by:

old in interface XGettingList<E>
