A signature requires the object either be constructed from the same FunctionTemplate (as e.g. new MyType() does), or from a FunctionTemplate that inherited from the signature's FunctionTemplate.
Note however that the "info.Holder" would still point at the receiver, and not the prototype with the matching signature :/ On Sun, May 28, 2017 at 7:27 PM Zac Hansen <xax...@gmail.com> wrote: > I create a "constructor" FunctionTemplate, create a signature from that > FunctionTemplate, then on that FunctionTemplate's PrototypeObject > ObjectTemplate, I create a bunch of FunctionTemplate's using the signature > I generated before. > > I can call the function with objects created directly from the > "constructor" FunctionTemplate.
