@Beta protected class ForwardingMap.StandardKeySet extends java.util.AbstractSet<E>
Map.keySet() in terms of the following
methods: ForwardingMap.clear(), ForwardingMap.containsKey(java.lang.Object),
ForwardingMap.isEmpty(), ForwardingMap.remove(java.lang.Object), ForwardingMap.size(), and the Set.iterator() method of ForwardingMap.entrySet(). In many cases, you may wish to override ForwardingMap.keySet() to forward to this implementation or a subclass
thereof.| Constructor and Description |
