Package com.intellij.util.containers

Class FactoryMap<K,V>

java.lang.Object

com.intellij.util.containers.FactoryMap<K,V>

All Implemented Interfaces:

java.util.Map<K,V>

public abstract class FactoryMap<K,V>
extends java.lang.Object
implements java.util.Map<K,V>

Map which computes the value associated with the key (via create(Object) method) on first get(Object) access. This map is NOT THREAD SAFE. For the thread-safe alternative please use ConcurrentFactoryMap instead.
