Entry: JS_GetConstructor (Function)
Summary: Retrieves the constructor for an object.
Syntax:
JSObject * JS_GetConstructor(JSContext *cx, JSObject *proto);
Argument Type Description
cx JSContext * Pointer to a JS context from which to derive runtime information.
proto JSObject * Pointer to the object for which to retrieve a constructor.
Description:
JS_GetConstructor retrieves the constructor for a specified object, proto. The constructor is a function that builds the object. If successful, JS_GetConstructor returns a pointer to the constructor object.
If proto does not have any properties, JS_GetConstructor returns NULL. If proto has properties, but it does not have an associated constructor function, JS_GetConstructor reports the lack of a constructor function and then returns NULL.
