public class LoopbackInvoker

extends CommandInvoker

This invoker calls a CommandExecutor which resides in the same VM. Travel of the ExternalizedCommand between client and server is simulated with serialization / deserialization in memory.

This is especially useful for building tests. Command implementors should not manipulate this class directly.
