C++ (Cpp) JS_UnwrapObject Examples

Example #1

File: jsd_val.cpp Project: JSilver99/mozilla-central

/*
 * Retrieve a JSFunction* from a JSDValue*. This differs from
 * JS_ValueToFunction by fully unwrapping the object first.
 */
JSFunction*
jsd_GetValueFunction(JSDContext* jsdc, JSDValue* jsdval)
{
    JSObject *obj;
    JSFunction *fun;

    JSCompartment* oldCompartment = NULL;
    if (JSVAL_IS_PRIMITIVE(jsdval->val))
        return NULL;

    obj = JS_UnwrapObject(JSVAL_TO_OBJECT(jsdval->val));
    oldCompartment = JS_EnterCompartment(jsdc->dumbContext, obj);
    fun = JS_ValueToFunction(jsdc->dumbContext, OBJECT_TO_JSVAL(obj));
    JS_LeaveCompartment(jsdc->dumbContext, oldCompartment);

    return fun;
}
