# = delegate -- Support for the Delegation Pattern
#
# Documentation by James Edward Gray II and Gavin Sinclair
#
# == Introduction
#
# This library provides three different ways to delegate method calls to an
# object. The easiest to use is SimpleDelegator. Pass an object to the
# constructor and all methods supported by the object will be delegated. This
# object can be changed later.
#
# Going a step further, the top level DelegateClass method allows you to easily
# setup delegation through class inheritance. This is considerably more
# flexible and thus probably the most common use for this library.
#
# Finally, if you need full control over the delegation scheme, you can inherit
# from the abstract class Delegator and customize as needed. (If you find
# yourself needing this control, have a look at _forwardable_, also in the
# standard library. It may suit your needs better.)
#
# == Notes
#
# Be advised, RDoc will not detect delegated methods.
#
# delegate.rb provides full-class delegation via the
# DelegateClass() method. For single-method delegation via
# def_delegator(), see forwardable.rb.
#
# == Examples
#
# === SimpleDelegator
#
# Here's a simple example that takes advantage of the fact that
# SimpleDelegator's delegation object can be changed at any time.
#
# class Stats
# def initialize
# @source = SimpleDelegator.new([])
# end
# 
# def stats( records )
# @source.__setobj__(records)
# 	
# "Elements: #{@source.size}\n" +
# " Non-Nil: #{@source.compact.size}\n" +
# " Unique: #{@source.uniq.size}\n"
# end
# end
# 
# s = Stats.new
# puts s.stats(%w{James Edward Gray II})
# puts
# puts s.stats([1, 2, 3, nil, 4, 5, 1, 2])
#
# Prints:
#
# Elements: 4
# Non-Nil: 4
# Unique: 4
# 
# Elements: 8
# Non-Nil: 7
# Unique: 6
#
# === DelegateClass()
#
# Here's a sample of use from tempfile.rb.
#
# A _Tempfile_ object is really just a _File_ object with a few special rules
# about storage location and/or when the File should be deleted. That makes for
# an almost textbook perfect example of how to use delegation.
#
# class Tempfile < DelegateClass(File)
# # constant and class member data initialization...
# 
# def initialize(basename, tmpdir=Dir::tmpdir)
# # build up file path/name in var tmpname...
# 
# @tmpfile = File.open(tmpname, File::RDWR|File::CREAT|File::EXCL, 0600)
# 
# # ...
# 
# super(@tmpfile)
# 
# # below this point, all methods of File are supported...
# end
# 
# # ...
# end
#
# === Delegator
#
# SimpleDelegator's implementation serves as a nice example here.
#
# class SimpleDelegator < Delegator
# def initialize(obj)
# super # pass obj to Delegator constructor, required
# @_sd_obj = obj # store obj for future use
# end
# 
# def __getobj__
# @_sd_obj # return object we are delegating to, required
# end
# 
# def __setobj__(obj)
# @_sd_obj = obj # change delegation object, a feature we're providing
# end
# 
# # ...
# end

#
# Delegator is an abstract class used to build delegator pattern objects from
# subclasses.  Subclasses should redefine \_\_getobj\_\_.  For a concrete
# implementation, see SimpleDelegator.
#
class Delegator
  IgnoreBacktracePat = %r"\A#{Regexp.quote(__FILE__)}:\d+:in `"

#
 # Pass in the _obj_ to delegate method calls to. All methods supported by
 # _obj_ will be delegated to.

  #
