Class ConcurrentHashMap.EntrySetView<K,V>

java.lang.Object
  net.sf.ehcache.util.concurrent.ConcurrentHashMap.EntrySetView<K,V>

All Implemented Interfaces:

Iterable<Map.Entry<K,V>>, Collection<Map.Entry<K,V>>, Set<Map.Entry<K,V>>

Enclosing class:

ConcurrentHashMap<K,V>

public static final class ConcurrentHashMap.EntrySetView<K,V>
extends Object
implements Set<Map.Entry<K,V>>

A view of a ConcurrentHashMap as a Set of (key, value) entries. This class cannot be directly instantiated. See ConcurrentHashMap.entrySet.

Method Summary

boolean	add(Map.Entry<K,V> e)
boolean	addAll(Collection<? extends Map.Entry<K,V>> c)
void	clear()
boolean	contains(Object o)
boolean	containsAll(Collection<?> c)
boolean	equals(Object o)
ConcurrentHashMap<K,V>	getMap() Returns the map backing this view.
int	hashCode()
boolean	isEmpty()
Iterator<Map.Entry<K,V>>	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.
boolean	remove(Object o)
boolean	removeAll(Collection<?> c)
boolean	retainAll(Collection<?> c)
int	size()
Object[]	toArray()
<T> T[]	toArray(T[] a)
String	toString()
