Method Detail

getMap

public ConcurrentHashMapV8<K,V> getMap()

Returns the map backing this view.

Returns:

the map backing this view

clear

public final void clear()

Removes all of the elements from this view, by removing all the mappings from the map backing this view.

Specified by:

clear in interface java.util.Collection<E>

size

public final int size()

Specified by:

size in interface java.util.Collection<E>

isEmpty

public final boolean isEmpty()

Specified by:

isEmpty in interface java.util.Collection<E>

iterator

public abstract java.util.Iterator<E> iterator()

Returns a "weakly consistent" iterator that will never throw ConcurrentModificationException, and guarantees to traverse elements as they existed upon construction of the iterator, and may (but is not guaranteed to) reflect any modifications subsequent to construction.

Specified by:

iterator in interface java.lang.Iterable<E>

Specified by:

iterator in interface java.util.Collection<E>

contains

public abstract boolean contains(java.lang.Object o)

Specified by:

contains in interface java.util.Collection<E>

remove

public abstract boolean remove(java.lang.Object o)

Specified by:

remove in interface java.util.Collection<E>

toArray

public final java.lang.Object[] toArray()

Specified by:

toArray in interface java.util.Collection<E>

toArray

public final <T> T[] toArray(T[] a)

Specified by:

toArray in interface java.util.Collection<E>

toString

public final java.lang.String toString()

Returns a string representation of this collection. The string representation consists of the string representations of the collection's elements in the order they are returned by its iterator, enclosed in square brackets ("[]"). Adjacent elements are separated by the characters ", " (comma and space). Elements are converted to strings as by String.valueOf(Object).

Overrides:

toString in class java.lang.Object

Returns:

a string representation of this collection

containsAll

Specified by:

containsAll in interface java.util.Collection<E>

removeAll

public final boolean removeAll(java.util.Collection<?> c)

Specified by:

removeAll in interface java.util.Collection<E>

retainAll

public final boolean retainAll(java.util.Collection<?> c)

Specified by:

retainAll in interface java.util.Collection<E>
