Class LRUMessageCache

  • All Implemented Interfaces:
    java.io.Serializable, java.lang.Cloneable, java.util.Map<java.lang.String,​java.lang.Integer>
    class LRUMessageCache
extends java.util.LinkedHashMap<java.lang.String,​java.lang.Integer>
    Clients of this class should only use the getMessageCountAndThenIncrement(java.lang.String) method. Other methods inherited via LinkedHashMap are not thread safe.
