Interface CacheStoreSession

public interface CacheStoreSession

Session for the cache store operations. The main purpose of cache store session is to hold context between multiple store invocations whenever in transaction. For example, if using JDBC, you can store the ongoing database connection in the session properties() map. You can then commit this connection in the CacheStore.txEnd(boolean) method.

CacheStoreSession can be injected into an implementation of CacheStore with @CacheStoreSessionResource annotation.
