Hey.
Have you considered getting „this“ from the „args“ parameter? This would allow
you to store callbacks in the local module. That is how I handled the issue of
storing a void* in the current instance.
It is ages ago that I coded with v8, but I think what you want is this:
Local<Object> _this = args.getHolder();
Please forgive me, but I pretty much forgot all about the API ^^“
Using the method I suggest is equivalent of this JS:
cApiBinding.prototype.call_func = function( uuid ) {
var cbs = this.callbacks; // <-
_c_lib_function( uuid, cbs[uuid] );
}
Hope it helped!
Kind regards, Ingwie
