Check Global method exist inside a class method

Hi all, I have a problem in identifying whether a global method exist or not, from inside class, My code is similar to,

2

Here "respond_to?("myMethod")" fails, It seems to be only checking the methods inside the class, not global methods.

top levels methods like that aren't 'global' methods, they end up as
private methods on Object.

Hi Frederick,

Did you mean I should check with, Object.respond_to?("myMethod"). But It still it didnt' work. Is that the Object you mention is not what I mean here? Can you please explain it little bit more?

Thanks Dimuthu

by default, respond_to doesn't check for private methods, but you can
force it : Object.respond_to?(:myMethod, true)
