so are XPC objects hooked up to work with instanceof? js> CLASS = Components.classes["nsEcho"] nsEcho js> IFACE = Components.interfaces["nsIEcho"] nsIEcho // seems like these should be true js> o = CLASS.createInstance() [xpconnect wrapped nsISupports] js> o instanceof CLASS false js> o instanceof IFACE false // just for curiousity's sake js> O = o.QueryInterface(IFACE) [xpconnect wrapped nsIEcho] js> O instanceof CLASS false js> O instanceof IFACE false

I had already been thinking about this. It is not yet obvious what the best strategy would be.

instanceof now works for Components.interfaces.* It will not work for Components.classes.* untill interface flattening is working. xpconnect does not store info on what CLSID was used to create the object. Even if it did so it would not work the same with objects that had been wrapped automatically; i.e. as the result of being passed in as an argument. When flattening is working and objects support an interface by which they can be queried for their CLSID then instanceof will be made to work for Components.classes.* and Components.classesByID.*
