Module: Concurrent::ReInclude

Included in:

Promises::FactoryMethods

Defined in:

lib/concurrent-ruby/concurrent/re_include.rb

Overview

Methods form module A included to a module B, which is already included into class C, will not be visible in the C class. If this module is extended to B then A's methods are correctly made visible to C.

Examples:

module A
  def a
    :a
  end
end

module B1
end

class C1
  include B1
end

module B2
  extend Concurrent::ReInclude
end

class C2
  include B2
end

B1.send :include, A
B2.send :include, A

C1.new.respond_to? :a # => false
C2.new.respond_to? :a # => true
