onWrite

public void onWrite(java.lang.String storeName)

Called when a simple write operation occurs. This invalidates all read lookups and all layered lookups.

onDelete

Called when a delete has occurred in a store. This invalidates both reads and write lookups in that store.

onSnapshot

public void onSnapshot(java.lang.String storeName)

Called when a snapshot occurs in a store. This invalidates write lookups. Read lookups stay untouched.

reset

public void reset()
