Class ThreadLocalMap<K,V>

java.lang.Object

com.technia.tvc.core.util.ThreadLocalMap<K,V>

All Implemented Interfaces:

java.util.Map<K,V>

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

This class implements a Map in which each thread that accesses it will have it's own set of key/value pairs. This map should be used to cache information that isn't thread safe.

Since:

3.6
