Implementing a VMC

public class myVMC implements VirtualMobileCode,

VMCManagedResources, ... , Serializable {

private MobileCodeStub stub = null; // Defined here but set by the MCM !

// Implement all methods of the (Virtual) MobileCode interface

public setStub (MobileCodeStub stub) { // Nobody but MCM should call this !

this.stub = stub;

}

.....

// Implement all methods of all other interfaces implemented

public aMethod (...) {

if (stub != null) {

stub.aMethod (...);

}

VMC Summary :

1) A VMC must implement VMCMobileCode ... which is an empty subclass of

MobileCode used only for type-casting within the MobileCodeManager

2) The toolkit provides a good starting point in users : An empty

VirtualManagedComponent (returns null when any data is queried) that

can easily be extended ... and filled. However, your subclass should implement

Serializable if you want to transport the VMC.

3) Perhaps we need a SuperVMC.java !
