Module: Blank

Included in:
Commander::Command::Options
Defined in:
lib/commander/blank.rb

Overview

Strips a class of (almost) all its instance methods, leaving it as a near-blank slate. Mixed into Commander::Command::Options so that method_missing can treat arbitrary option names as accessors without clashing with methods Ruby defines on every object (e.g. send, type).

.included(base) ⇒ Object

Undefines every instance method on base except those beginning with a double underscore and object_id, which are kept so the resulting object remains minimally usable (e.g. for __send__ and identity checks).
