# frozen_string_literal: false
#
#   forwardable.rb -
#       $Release Version: 1.1$
#       $Revision$
#       by Keiju ISHITSUKA(keiju@ishitsuka.com)
#       original definition by delegator.rb
#       Revised by Daniel J. Berger with suggestions from Florian Gross.
#
#       Documentation by James Edward Gray II and Gavin Sinclair

# The Forwardable module provides delegation of specified
# methods to a designated object, using the methods #def_delegator
# and #def_delegators.
#
# For example, say you have a class RecordCollection which
# contains an array <tt>@records</tt>.  You could provide the lookup method
# #record_number(), which simply calls #[] on the <tt>@records</tt>
# array, like this:
#
#   require 'forwardable'
#
#   class RecordCollection
#     attr_accessor :records
#     extend Forwardable
#     def_delegator :@records, :[], :record_number
#   end
#
# We can use the lookup method like so:
#
#   r = RecordCollection.new
#   r.records = [4,5,6]
#   r.record_number(0)  # => 4
#
# Further, if you wish to provide the methods #size, #<<, and #map,
# all of which delegate to @records, this is how you can do it:
#
#   class RecordCollection # re-open RecordCollection class
#     def_delegators :@records, :size, :<<, :map
#   end
#
#   r = RecordCollection.new
#   r.records = [1,2,3]
#   r.record_number(0)   # => 1
#   r.size               # => 3
#   r << 4               # => [1, 2, 3, 4]
#   r.map { |x| x * 2 }  # => [2, 4, 6, 8]
#
# You can even extend regular objects with Forwardable.
#
#   my_hash = Hash.new
#   my_hash.extend Forwardable              # prepare object for delegation
#   my_hash.def_delegator "STDOUT", "puts"  # add delegation for STDOUT.puts()
#   my_hash.puts "Howdy!"
#
# == Another example
#
# You could use Forwardable as an alternative to inheritance, when you don't want
# to inherit all methods from the superclass. For instance, here is how you might
# add a range of +Array+ instance methods to a new class +Queue+:
#
#   class Queue
#     extend Forwardable
#
#     def initialize
#       @q = [ ]    # prepare delegate object
#     end
#
#     # setup preferred interface, enq() and deq()...
#     def_delegator :@q, :push, :enq
#     def_delegator :@q, :shift, :deq
#
#     # support some general Array methods that fit Queues well
#     def_delegators :@q, :clear, :first, :push, :shift, :size
#   end
#
#   q = Queue.new
#   q.enq 1, 2, 3, 4, 5
#   q.push 6
#
#   q.shift    # => 1
#   while q.size > 0
#     puts q.deq
#   end
#
#   q.enq "Ruby", "Perl", "Python"
#   puts q.first
#   q.clear
#   puts q.first
#
# This should output:
#
#   2
#   3
#   4
#   5
#   6
#   Ruby
#   nil
#
# == Notes
#
# Be advised, RDoc will not detect delegated methods.
#
# +forwardable.rb+ provides single-method delegation via the def_delegator and
# def_delegators methods. For full-class delegation via DelegateClass, see
# +delegate.rb+.
