java.lang.Object
org.elasticsearch.util.collect.ForwardingObject
org.elasticsearch.util.collect.ForwardingMap<K,V>
org.elasticsearch.util.collect.ForwardingSortedMap<K,V>
- All Implemented Interfaces:
- java.util.Map<K,V>, java.util.SortedMap<K,V>
public abstract class ForwardingSortedMap<K,V>
- extends ForwardingMap<K,V>
- implements java.util.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
public ForwardingSortedMap()
delegate
protected abstract java.util.SortedMap<K,V> delegate()
- Description copied from class:
ForwardingObject
- Returns the backing delegate instance that methods are forwarded to.
Abstract subclasses generally override this 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.
