mixin-based Classes

Hi,

I'm extracting classes and stuff from a deployed btd file. The the source code went mising after the IT provider bit the dust ... and they used a pretty weird class called Framework.mixin. Unfortunately another place I found the culprit is

file $FORTE_ROOT/userapp/forte/cl0/forte.btd

Plan : TOOLDebugger

Class : qqdg_Break

public attribute qqdg_Break.MethodCode : Framework.mixin (SP_TYPE_MIXIN)

funny enought the SP_TYPE_MIXIN const is defined in the Framework plan but not the mixin class.

I'd be grateful if anybody got any kind of information on how to define/access templatized super classes from the workshop.

Thanks,

Finally got a beginning of an answer : MIXIN type refers to any of the Fort?internal classes that do not inherit from Object (for instance in Plan TOOLInterpreter the class qqrt_IRBlock inherits from qqrp_NamedElement AND qqlo_MethodCode, qqlo_MethodCode does not have a superclass and is a MIXIN).

Unfortunately when a method is returning a MIXIN the MethodDesc.GetReturnType remains very vague about the returned type and defaults it to MIXIN.

By the way there are some other reflexion limitations, virtual attributes, functions returning events ...
