Creating Instance

WrappedStateStore takes the following to be created:

Abstract Class

WrappedStateStore is an abstract class and cannot be created directly. It is created indirectly for the concrete WrappedStateStores.


boolean setFlushListener(
  CacheFlushListener<K, V> listener,
  boolean sendOldValues)

setFlushListener returns false for the wrapped state store being of any type but a CachedStateStore.

Otherwise, setFlushListener returns the value of requesting the CachedStateStore to setFlushListener.

setFlushListener is part of the CachedStateStore abstraction.
