Registers the cache. The registration will be permanent if setPermanentCacheID(String) was called before, otherwise temporary.

Throws:

java.sql.SQLException

registerPermanentCache

public void registerPermanentCache(java.lang.String cacheID)
                            throws java.sql.SQLException

Registers a permanent cache identifier.

Parameters:

cacheID - cache identifier to be registered

Throws:

java.sql.SQLException

unRegisterCache

public void unRegisterCache()
                     throws java.sql.SQLException

Unregisters the cache.

Throws:

java.sql.SQLException

unRegisterCache

public void unRegisterCache(java.lang.String cacheID)
                     throws java.sql.SQLException

Unregisters the given cache identifier.

Parameters:

cacheID - cache identifier to unregister

Throws:

java.sql.SQLException

timestampExists
