Enum JamPolicy

java.lang.Object

java.lang.Enum<JamPolicy>

com.trivago.triava.tcache.JamPolicy

All Implemented Interfaces:

Serializable, Comparable<JamPolicy>

public enum JamPolicy
extends Enum<JamPolicy>

The JamPolicy defines behavior when there is a jam in the cache. A jam is the situation when the cache is (over)full and a new element should be put into the cache. The Cache.put() method will either wait for free space (WAIT) or not add the new element (DROP).
