Class LRUMessageCache

java.lang.Object

java.util.AbstractMap<K,V>

java.util.HashMap<K,V>

java.util.LinkedHashMap<java.lang.String,java.lang.Integer>

ch.qos.logback.classic.turbo.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.
