Method Detail

createEntrySet

protected java.util.Set<java.util.Map.Entry<K,V>> createEntrySet()

Description copied from class: Maps.ViewCachingAbstractMap

Creates the entry set to be returned by Maps.ViewCachingAbstractMap.entrySet(). This method is invoked at most once on a given map, at the time when entrySet is first called.

Specified by:

createEntrySet in class Maps.ViewCachingAbstractMap<K,V>

createKeySet

java.util.Set<K> createKeySet()

Overrides:

createKeySet in class Maps.ViewCachingAbstractMap<K,V>

containsKey

public boolean containsKey(java.lang.Object key)

Specified by:

containsKey in interface java.util.Map<K,V>

Overrides:

containsKey in class Maps.AbstractFilteredMap<K,V>
