Class SafeClientRepository

java.lang.Object

org.apache.jackrabbit.rmi.client.ClientObject

org.apache.jackrabbit.rmi.client.SafeClientRepository

All Implemented Interfaces:

javax.jcr.Repository

public abstract class SafeClientRepository
extends ClientObject
implements javax.jcr.Repository

A "safe" local adapter for the JCR-RMI RemoteRepository interface. This class uses an abstract factory method for loading (and reloading) the remote repository instance that is made locally available through the JCR Repository interface. If the remote reference breaks (a RemoteException is thrown by a remote call), then this adapter attempts to reload the remote reference once before failing.
