public class verboseChannel

extends channelCore

implements channelInterface

realizes a multi-channel of kind verbose. Its meta-behavior consists in printing messages stressing the flow of trapped calls through the multi-channel components. It uses instances of verboseSenderStub class as senderStubs, and instances of verboseReceiverStub as receiverStubs

verboseChannel

public verboseChannel(java.lang.String[] RsName)
               throws uka.karmi.rmi.RemoteException,
                      ReceiverStubNotFoundException

constructor of multi-channels of kind verbose. It calls the channelCore constructor with kind verbose and as classes for sender and receiver stubs their verbose version.

Parameters:

RsName - an Array of Strings representing the name of the receivers, which it is connected to.

Throws:

ReceiverStubNotFoundException - thrown when one of the specified receiver wasn't started before the core.

verboseChannel

public verboseChannel(java.lang.String kind,
                      java.lang.String[] RsName,
                      java.lang.String SSClassName,
                      java.lang.String RSClassName)
               throws uka.karmi.rmi.RemoteException,

Method Detail

coreMetaBehavior

public java.lang.Object coreMetaBehavior(mChaRMMethodCall msg)
                                  throws MethodDoesNotExistException,
                                         uka.karmi.rmi.RemoteException

This method embodies the reflective behaviour realized by the multi-channel. Its behavior consists in printing information about the call trapped and then applies the # coreMetaBehavior of its ancestor.

Specified by:

coreMetaBehavior in interface channelInterface

Overrides:

coreMetaBehavior in class channelCore

Parameters:

RsName - the name of the receivers who the message have to be delivered to.

methodName - the name of the method whose execution is requested.

args - the actual arguments of the call.

Returns:

the result of the method call.

Throws:

MethodDoesNotExistException - thrown when the method reified doesn't exist in the referent class.
