Reflection and private methods in gosu

[extenditus]

How can i invoke a private method in gosu from another class using reflection?

I am basically trying to do this

method = object.getClass().getDeclaredMethod(methodName);
method.setAccessible(true);
Object r = method.invoke(object);

Any direction would help. 
Thanks.

Here's an example:

var s = "This is a string"

var m = s.Class.getDeclaredMethod( "checkBounds", {byte[], int, int} )

m.Accessible = true

m.invoke( s, {s.Bytes, 0, 1} )

Cheers,

Carson

 Thanks Carson.

 Is there a way to do the same thing from the TypeSystem.

e.g
  var s =""
  ( typeof s).<path to private method>

A little verbose, but it works:

uses gw.lang.reflect.IRelativeTypeInfo

var s = "This is a string"

var type = typeof s

var m = (type.TypeInfo as IRelativeTypeInfo).getMethod( type, "checkBounds", {byte[], int, int} )

m.CallHandler.handleCall( s, {s.Bytes, 0, 1} )

Depending on your version of Gosu, you may not need to cast to IRelativeTypeInfo to access the getMethod(IType, name, argTypes) method, I don't have access to the code base now, but I know there was talk about moving that method up to ITypeInfo at one point.

And, to be very safe, you probably want to test if the thing is an IRelativeTypeInfo using Gosu's handy-dandy auto-downcasting:

if( type.TypeInfo typeis IRelativeTypeInfo ) {

  var m = type.TypeInfo.getMethod( type, "checkBounds", {byte[], int, int} )

  m.CallHandler.handleCall( s, {s.Bytes, 0, 1} )

} else {

  var m = type.TypeInfo.getMethod( "checkBounds", {byte[], int, int} )

  m.CallHandler.handleCall( s, {s.Bytes, 0, 1} )

}

Thanks Carson! I will give that a try in the morning.
