Package org.apache.jackrabbit.oak.plugins.document.persistentCache

Class CacheMap<K,​V>

  • Type Parameters:
    K - the key type
    V - the value type
    public class CacheMap<K,​V>
extends java.lang.Object
    A cache map. This map supports re-opening the store if this is needed.

    Note that a failure to open the underlying store will be handled gracefully, in that the CacheMap can be constructed, but will not actually cache anything. The same is true for the case where the underlying store starts to fail and can not be re-opened.
