在JRuby中投射对象

Question

I still don't feel like this is adequately answered. how does one do this in jruby:

MyClass myobj = new MyClass;
InheritsFromMyClass changedobj = (InheritsFromMyClass)myobj;

Answer 1

Since Ruby is a dynamically typed language you do not need to cast the type:

myobj = MyClass.new
changedobj = myobj
