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

ForwardingSortedMap
protected ForwardingSortedMap(SortedMap<K,V> delegate)
- Constructs a forwarding sorted map that forwards to the provided delegate.
delegate
protected SortedMap<K,V> delegate()
- Description copied from class:
ForwardingObject
- Returns the backing delegate object. This method should be overridden to
specify the correct return type. For example:
@SuppressWarnings("unchecked")
@Override protected Foo delegate() {
return (Foo) super.delegate();
}
This method should always return the same delegate instance that was passed
to the constructor.
