Module: Mutex_m

Relationships & Source Files
Defined in: lib/mutex_m.rb

Overview

mutex_m.rb

When 'mutex_m' is required, any object that extends or includes Mutex_m will be treated like a Mutex.

Start by requiring the standard library Mutex_m:

require "mutex_m.rb"

From here you can extend an object with Mutex instance methods:

obj = Object.new
obj.extend Mutex_m

Or mixin Mutex_m into your module to your class inherit Mutex instance methods — remember to call super() in your class initialize method.

class Foo
  include Mutex_m
  def initialize
    # ...
    super()
  end
  # ...
end
obj = Foo.new
# this obj can be handled like Mutex
