Constructor Detail

WrapperCollections.ConcurrentWrapperMap

public WrapperCollections.ConcurrentWrapperMap(java.util.Map map)

Create an ConcurrentWrapperMap which delegates to the specified Map.

Parameters:

map - the Map to delegate all calls to

WrapperCollections.ConcurrentWrapperMap

protected WrapperCollections.ConcurrentWrapperMap(java.util.Map map,
                                                  java.util.concurrent.locks.ReadWriteLock lock)

Create an ConcurrentWrapperMap which delegates to the specified Map.

Parameters:

map - the Map to delegate all calls to

lock - a read/write lock for concurrency management

WrapperCollections.ConcurrentWrapperMap

protected WrapperCollections.ConcurrentWrapperMap(java.util.Map map,
                                                  java.util.concurrent.locks.ReadWriteLock lock,
