ProtectedConstructor

Provides a module that may be included in a Ruby class, that protects the constructor; good for enforcing instantiation of classes using, for instance, a class factory.

Installation

Add this line to your application's Gemfile:

gem 'ProtectedConstructor'

And then execute:

$ bundle

Or install it yourself as:

$ gem install ProtectedConstructor

Usage

require 'ProtectedConstructor'

class Klass
  include ProtectedConstructor

  def initialize
  end
end

module KlassFactory
  class << self
    public
    def create
      Klass.send(:new)
    end
  end
end

  Constructor is not protected.
klass = Klass.new   NoMethodError

  Example using factory...
klass = KlassFactory::create   works
klass.nil?   false
klass.is_a?(Klass)   true

  Example just using  send...
klass = Klass.send(:new)   works
klass.nil?   false
klass.is_a?(Klass)   true
