Class InternCache

java.lang.Object

java.util.AbstractMap<K,V>

java.util.HashMap

com.ctc.wstx.util.InternCache

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, java.util.Map

public final class InternCache
extends java.util.HashMap

Singleton class that implements "fast intern" functionality, essentially adding a layer that caches Strings that have been previously intern()ed, but that probably shouldn't be added to symbol tables. This is usually used by improving intern()ing of things like namespace URIs.

Note: that this class extends HashMap is an implementation detail -- no code should ever directly call Map methods.
