InterType Declarations InterType Declarations are a useful Iand popular) way of adding functionality to an object, usually to the prototype of a constructor.
Lets say I have a class Widget that I want to borrow from: class Widget { private function Widget(){} static { getByNode : function():Widget { } } prototype { var isBeingDragged : false, valueOf : function(){ }, toString : function():String { }, } function moveTo(x, y){ } } Class Orangutan {} // Borrows from Widget In ES3, I can use a crossCut function: crossCut : function(receiver, supplier, propsArray, borrowFilter) { } What is the ES4 way to introspect or modify or a class? I want to provide beforeAdvice to the static Widget.getInstance. For other Orangutan, I want to provide afterAdvice to the constructor (add to pool) (or is this aroundAdvice?). I want to borrow the prototype properties of Widget, to Orangutan (for default read access) I want to borrow the static methods. Is this done through the traits? Can I modify a sealed class? My understanding is that a sealed class' instances can't have dynamic props. what about the class itself? Also, is there a way to get the function name from an anonymous function via the identifier it's bound with, or do I have to type: getByNode: function getByNode():Widget{ }. I find the repetition annoying to my hands and eyes. I want access to the function name without having to do this. -- Programming is a collaborative art. _______________________________________________ Es4-discuss mailing list Es4-discuss@mozilla.org https://mail.mozilla.org/listinfo/es4-discuss
