Class InternCache
- All Implemented Interfaces:
Serializable
,Cloneable
,Map<String,
String>
Singleton class that adds a simple first-level cache in front of
regular String.intern() functionality. This is done as a minor
performance optimization, to avoid calling native intern() method
in cases where same String is being interned multiple times.
Note: that this class extends LinkedHashMap
is an implementation
detail -- no code should ever directly call Map methods.
