Module: ClassMethods

Included in:
AClass
Defined in:
lib/carat-dev/class-constructor/constructor_methods.rb

Overview

ClassMethods

This allows all classes to be instantiated via methods of the same name, rather then having to use #new. Because these methods are capitalized, like their class couterpart, parenthesis are required.

Example

require 'carat-dev/class_methods'

class AClass
  include ClassMethods
  def initialize(a)
    @a = a
  end
end

aobj = AClass(1)   # same as AClass.new(1)

class BClass < AClass
end

bobj = BClass(2)   # same as BClass.new(2)
