Class DeferredOperationsCache

java.lang.Object
  com.atlassian.confluence.cache.CacheAdapter
      com.atlassian.confluence.cache.DeferredOperationsCache

All Implemented Interfaces:

com.atlassian.cache.Cache

public class DeferredOperationsCache
extends CacheAdapter

An implementation of Cache that records changes to a delegate cache, only actually performing them when sync() is called. Deferred operations are still visible to the client, the actions are just not taken on the delegate cache.

For example, calling put(Object, Object) will not update the delegate cache, but the value will still be recorded for subsequent calls to get(Object) for the same key. Once sync() is called, the new value will be inserted in the delegate cache.

Objects of this class are NOT thread-safe. It is the client's responsibility to ensure serialized access to this object.
