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

org.glassfish.ha.store.api.BackingStoreFactory
A factory for creating BackingStore(s). Every provider must provide an implementation of this interface.
The createBackingStore(env) method is called typically during container creation time. A store instance is typically used to store state for a single container.
Any runtime exception thrown from createBackingStore and createBatchBackingStore method will cause the container to use a default persistence-type (typically no replication) and a log message will be logged at WARNING level. @author Mahesh Kannan
