RE: HOOKS

Hi Rana,

You can have a look at org.smartfrog.services.trace.SFTrace.java for an
example that uses the lifecycle hooks.

There is one set of hooks per lifecycle method and the hooks are
available in any component implementing PrimImpl.

To add a hook inside a component you have to use:

//Deploy Hook
sfDeployHooks.addHook(sfDeployTracer);

//StartHook
sfStartHooks.addHook(sfStartTracer);
//TeminateWithHook
sfTerminateWithHooks.addHook(sfTerminateWithTracer);


The listener for the hook has to implement the interface PrimHook.
org.smartfrog.sfcore.prim.PrimHook;

An example can be:

    /**
     * Example of hook listener
     */
    private class SfDeployTracer implements PrimHook {
        public void sfHookAction(Prim prim, TerminationRecord tr)
            throws SmartFrogException {
	    //Your code.
            System.out.println(" ... ");
        }
    }

One more thing, the hooks are blocking.

Regards, 
	Julio Guijarro.
