protected class ForwardingMap.StandardKeySet extends Maps.KeySet<K,V>
A sensible implementation ofMap.keySet()
in terms of the following methods:ForwardingMap.clear()
,ForwardingMap.containsKey(java.lang.Object)
,ForwardingMap.isEmpty()
,ForwardingMap.remove(java.lang.Object)
,ForwardingMap.size()
, and theSet.iterator()
method ofForwardingMap.entrySet()
. In many cases, you may wish to overrideForwardingMap.keySet()
to forward to this implementation or a subclass thereof.- Since:
