# = 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.
|
|
|
|
#
|
|
|
|
# class Foo
|
|
|
|
# include Mutex_m
|
|
|
|
# # ...
|
|
|
|
# end
|
|
|
|
# obj = Foo.new
|
|
|
|
# # this obj can be handled like Mutex
|
|
