Hi,
I'm using JavaScriptCore and have created a custom class to be used
within the global context. I've defined a constructor callback with
the signature of JSObjectCallAsConstructorCallback:
JSObjectRef PointConstructor(JSContextRef ctx, JSObjectRef
constructor, size_t argumentCount, const JSValueRef arguments[],
JSValueRef* exception);
and set the returned object as the value of the Point property on
the global object. When the interpreter encounters the line var p =
new Point(); it calls things correctly and I'm able to create my
Point object and it works properly in the scripting environment.
I'm interested in generalizing my code so that I could have a single
constructor callback function for multiple objects, and based on the
value of the constructor argument, create the correct object.
Can any information (e.g., name or JSClassRef) about the class being
constructed be extracted from the constructor argument? I don't get
any enumerable properties from it. I did noticed that the memory
address of the constructor argument is identical to the one that I
got when I called JSObjectMakeConstructor() and set it as a property
on the global object.
Also, there doesn't seem to be a way to look up the name (or any other
information) on a JSClassRef object. It would be nice to have a
function to get back a copy of the JSClassDefinition used to create
the class.
Thanks,
Dan
