|
| 6 | *
|
| 7 | * Because all languages have different casing and case sensitivity rules,
|

|
| 11 | *
|
| 12 | * let myObj = new MyObject();
|
| 13 | *
|
| 14 | * let methods = MethodReflector.getMethodNames();
|
| 15 | * MethodReflector.hasMethod(myObj, "myMethod");
|
| 16 | * MethodReflector.invokeMethod(myObj, "myMethod", 123);
