Description copied from class: ClusteringInterceptor

Retrieves a cache entry from a remote source. Would typically involve an RPC call using a ClusteredGetCommand and some form of quorum of responses if the responses returned are inconsistent - often the case if there is a rehash in progress, involving nodes that the key maps to.

Specified by:

retrieveFromRemoteSource in class ClusteringInterceptor

Parameters:

key - key to look up

isWrite - true if this is triggered by a write operation

Returns:

an internal cache entry, or null if it cannot be located

Throws:

Exception

                             DataWriteCommand command)

Throws:

                                      throws Throwable
