- All Implemented Interfaces:
- ConcurrentMap<K,V>, Map<K,V>
public abstract class ForwardingConcurrentMap<K,V>
- extends ForwardingMap<K,V>
- implements ConcurrentMap<K,V>
A concurrent map which forwards all its method calls to another concurrent
map. Subclasses should override one or more methods to modify the behavior of
the backing map as desired per the decorator pattern.

ForwardingConcurrentMap
public ForwardingConcurrentMap()
delegate
protected abstract ConcurrentMap<K,V> delegate()
- Description copied from class:
ForwardingObject
- Returns the backing delegate instance that methods are forwarded to.
Abstract subclasses generally override the
ForwardingObject
method
with an abstract method that has a more specific return type, such as
ForwardingSet.delegate()
. Concrete subclasses override this method to
supply the instance being decorated.
