Class WrapperCollections.ConcurrentWrapperEntrySet

java.lang.Object
com.tangosol.util.WrapperCollections.ConcurrentWrapperCollection
com.tangosol.util.WrapperCollections.ConcurrentWrapperSet
com.tangosol.util.WrapperCollections.ConcurrentWrapperEntrySet

All Implemented Interfaces:

java.lang.Iterable, java.util.Collection, java.util.Set

Enclosing class:

WrapperCollections

public static class WrapperCollections.ConcurrentWrapperEntrySet

extends WrapperCollections.ConcurrentWrapperSet

implements java.util.Set

Map Entry Set implementation which uses a ReadWriteLock to manage concurrent access to the underlying Entry objects.

Since:

Coherence 3.7

Field Summary

protected boolean

m_fStrict Determines whether or not all of the Entry methods are protected; if set to true, then all Entry methods are protected.

Constructor Summary

protected

WrapperCollections.ConcurrentWrapperEntrySet(java.util.Set set, java.util.concurrent.locks.ReadWriteLock lock, boolean fStrict) Create an ConcurrentWrapperSet which delegates to the specified Set.

Field Detail

m_fStrict

protected final boolean m_fStrict

Determines whether or not all of the Entry methods are protected; if set to true, then all Entry methods are protected.

Constructor Detail

WrapperCollections.ConcurrentWrapperEntrySet

protected WrapperCollections.ConcurrentWrapperEntrySet(java.util.Set set,
                                                       java.util.concurrent.locks.ReadWriteLock lock,
                                                       boolean fStrict)

Create an ConcurrentWrapperSet which delegates to the specified Set.

Parameters:

set - the Set to delegate all calls to

lock - a read/write lock for concurrency management

fStrict - pass true to protect all Entry methods; false to protect only the setValue() method

Method Detail

iterator

public java.util.Iterator iterator()

Returns an iterator over the elements in this collection. There are no guarantees concerning the order in which the elements are returned (unless this collection is an instance of some class that provides a guarantee).
