Class AbstractRhqFacadeProxy<T extends RhqFacade>

java.lang.Object
  org.rhq.bindings.client.AbstractRhqFacadeProxy<T>

All Implemented Interfaces:

InvocationHandler

public abstract class AbstractRhqFacadeProxy<T extends RhqFacade>
extends Object
implements InvocationHandler

An abstract InvocationHandler to help the script users create proxies to actually call the correct methods on RHQ. This base implementation provides its inheritors with the facade impl and the concrete manager they should invoke the methods on and does the "de-simplification" of the arguments (i.e. the opposite of InterfaceSimplifier.simplify(Class).

invoke

public Object invoke(Object proxy,
                     Method method,
                     Object[] args)
              throws Throwable

Specified by:

Throws:

Throwable

doInvoke

protected abstract Object doInvoke(Object proxy,
                                   Method originalMethod,
                                   Class<?>[] argTypes,
                                   Object[] args)
                            throws Throwable

This method actually calls the method according to the RhqFacade's implementation. The argTypes and args are de-simplified (and thus the method can't be supplied just as a simple Method instance).

Parameters:

proxy - the proxy the method is executing on

originalMethod - the original method

argTypes - the de-simplified argument types

args - the de-simplified argumens

Returns:

the result of the invocation

Throws:

Throwable - if invocation throws an error
