rubyintrospection

In Ruby, is there a way to find the class that responds to a method call?

So, in Ruby, if I have a class hierarchy that looks something like (very symbolically)

A < B < C < Object

and have a method "foo" defined in class C, is there some bit of introspection that allows me to determine that C is the class defining the method that responds to A.new.foo?

Solution

  • Yes... do A.new.method(:foo).owner. It will give you class C. Read #owner.
