Parameters:

name - - the name to use for this interceptor

 protected Object create(Invocation invocation,
    DeploymentInfo di) throws Throwable 
{
      return invokeNext(invocation);
}

 protected Object destroy(Invocation invocation,
    DeploymentInfo di) throws Throwable 
{
      return invokeNext(invocation);
}

 protected Object init(Invocation invocation,
    DeploymentInfo di) throws Throwable 
{
      return invokeNext(invocation);
}

 public Object invoke(Invocation invocation) throws Throwable 
{
      String type = invocation.getType();
      // make sure this is an operation invocation
      if (type.equals(Invocation.OP_INVOKE))
      {
         Object args[] = invocation.getArgs();
         Object retn = invocation.getReturnTypeClass();
         // make sure the signature matches - > void < methodName >(DeploymentInfo di)
         if ((args.length == 1) && (args[0] instanceof DeploymentInfo) && (retn == null))
         {         
            String method = invocation.getName();
            DeploymentInfo di = (DeploymentInfo)args[0];
            if (method.equals("init"))
            {
               return init(invocation, di);
            }
            else if (method.equals("create"))
            {
               return create(invocation, di);
            }
            else if (method.equals("start"))
            {
               return start(invocation, di);
            }
            else if (method.equals("stop"))
            {
               return stop(invocation, di);
            }
            else if (method.equals("destroy"))
            {
               return destroy(invocation, di);
            }
         }
      }
      // if we reached this point invocation is of no interest
      // to SubDeployerInterceptor so simply forward it
      return invokeNext(invocation);
}

This invoke method checks for invocations of interest, .i.e. init(), create(), start(), stop(), destroy() operation calls with a single DeploymentInfo argument and wraps the invocation with calls to corresponding init(), create(), etc. methods.

 protected Object invokeNext(Invocation invocation) throws Throwable 
{
      // call the next in the interceptor chain,
      // if nobody follows dispatch the call
      Interceptor next = invocation.nextInterceptor();
      if (next != null)
      {
         return next.invoke(invocation);
      }
      else
      {
         return invocation.dispatch();
      }
}

Use this to forward the call

 protected Object start(Invocation invocation,
    DeploymentInfo di) throws Throwable 
{
      return invokeNext(invocation);
}

 protected Object stop(Invocation invocation,
    DeploymentInfo di) throws Throwable 
{
      return invokeNext(invocation);
}
