Class InternCache
java.lang.Object
java.util.AbstractMap<K,V>
java.util.HashMap<K,V>
java.util.LinkedHashMap<String,String>
com.fasterxml.jackson.core.util.InternCache
- All Implemented Interfaces:
- Serializable, Cloneable, Map<String,String>
public final class InternCache
- extends LinkedHashMap<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.
