      extended by org.smartfrog.sfcore.prim.PrimImpl
          extended by org.smartfrog.examples.helloworld.GeneratorImpl
All Implemented Interfaces:
java.lang.Runnable, java.rmi.Remote, MessageKeys, Diagnostics, Liveness, Prim, RemoteReferenceResolver, RemoteReferenceResolverHelper

public class GeneratorImpl
extends PrimImpl
implements Prim, java.lang.Runnable

Basic example component. The Generator component (in generator.sf) is a basic primitive component so its component description class GeneratorImpl extends PrimImpl (the base class for all the deployed components) which provides the default lifecycle template methods for a primitive component. Although PrimImpl itself implements Prim (the base interface for all the deployed components) CounterImpl also implements Prim because it is necessary for RMI that component also does so; the rmic compiler will otherwise not behave correctly. The GeneratorImpl class needs to be prepared for RMI for remote deployment This is done by creating and compiling the stubs and skeletons using the rmic compiler. This class is included in rmitargets that is read by the rmic compiler.

Constructor Summary

          Constructor for the Generator object.
 
Method Summary
 void run()
          Main processing method for the Generator object (implements 'Runnable').
 void sfDeploy()
          sfDeploy: reads Generator attributes.
 void sfStart()
          sfStart: starts genrator thread.
 void sfTerminateWith(TerminationRecord tr)
          sfTerminate: terminate the thread nicely if needed could interrupt its sleep, but not necessary in general, since the thread initiates the termination, this will be irrelevant but to do so in case it is through error or management action.
