use of com.github.anba.es6draft.runtime.types.builtins.BuiltinConstructor in project es6draft by anba.

the class Bootstrap method constructSetup.

private static MethodHandle constructSetup(MutableCallSite callsite, Object constructor, ExecutionContext cx, Object[] arguments) {
    MethodHandle target, test;
    if (constructor instanceof FunctionObject && constructor instanceof Constructor) {
        FunctionObject fn = (FunctionObject) constructor;
        test = MethodHandles.insertArguments(testFunctionObjectMH, 1, fn.getMethodInfo());
        target = fn.getConstructMethod();
    } else if (constructor instanceof BuiltinConstructor) {
        BuiltinConstructor fn = (BuiltinConstructor) constructor;
        test = MethodHandles.insertArguments(testBuiltinFunctionMH, 1, fn.getMethodInfo());
        target = fn.getConstructMethod();
    } else {
        target = test = null;
    }
    if (target != null) {
        // Insert constructor as newTarget argument.
        target = target.asType(target.type().changeParameterType(2, constructor.getClass()));
        target = MethodHandles.permuteArguments(target, target.type().dropParameterTypes(2, 3), 0, 1, 0, 2);
    }
    return setCallSiteTarget(callsite, target, test, constructGenericMH);
}
