Class: Pry::Method::Disowned

Inherits:
Pry::Method show all
Defined in:
lib/pry/method/disowned.rb

Overview

A Disowned Method is one that’s been removed from the class on which it was defined.

e.g. class C

def foo
  C.send(:undefine_method, :foo)
  Pry::Method.from_binding(binding)
end

end

In this case we assume that the “owner” is the singleton class of the receiver.

This occurs mainly in Sinatra applications.

Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(method_name, *args, &block) ⇒ Object

Raise a more useful error message instead of trying to forward to nil. rubocop:disable Style/MethodMissingSuper
