Package com.fasterxml.jackson.core.util
Class InternCache
- All Implemented Interfaces:
Serializable,ConcurrentMap<String,,String> 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.
