Examples of org.glassfish.ha.store.api.BackingStore

org.glassfish.ha.store.api.BackingStore
An object that stores a given value against an id. This class defines the set of operations that a container could perform on a store.

An instance of BackingStore is created by calling BackingStoreFactory.createBackingStore() method.

The BackingStore instance is created and used for storing data that belongs to a single application or container.

The store implementation must be thread safe.
