Module: DumbDelegator::TripleEqualExt

Defined in:
lib/dumb_delegator/triple_equal_ext.rb

Overview

This optional extension enables a Class/Module to support case statements.

Specifically, it monkey-patches a Class/Module’s :=== method to check if the other argument is an instance of the extended Class/Module.

target = MyAwesomeClass.new dummy = DumbDelegator.new(target)

MyAwesomeClass === dummy #=> false DumbDelegator === dummy #=> true

MyAwesomeClass.extend(DumbDelegator::TripleEqualExt)

MyAwesomeClass === dummy #=> true DumbDelegator === dummy #=> true

Examples:

Extending a Class/Module to handle class equality for a DumbDelegator instance.
