=begin
= Forwardable

クラスに対しメソッドの委譲機能を定義します.

== 使い方

クラスに対してextendして使います.

class Foo
    extend Forwardable

def_delegators("@out", "printf", "print")
    def_delegators(:@in, :gets)
    def_delegator(:@contents, :[], "content_at")
  end
  f = Foo.new
  f.printf ...
  f.gets
  f.content_at(1)

== メソッド

--- Forwardable#def_instance_delegators(accessor, *methods)

((|methods|))で渡されたメソッドのリストを((|accessorに|))委譲する
      ようにします.

--- Forwardable#def_instance_delegator(accessor, method, ali = method)

((||method|))で渡されたメソッドを((|accessor|))に委譲するようにし
      ます. ((|ali|))が引数として渡されたときは, メソッド((|ali|))が呼ば
      れたときには, ((|accessor|))に対し((|method|))を呼び出します.

--- Forwardable#def_delegators(accessor, *methods)

((|Forwardable#def_instance_delegators|))の別名です.

--- Forwardable#def_delegator(accessor, method, ali = method)

((|Forwardable#def_instance_delegator|))の別名です.

= SingleForwardable

オブジェクトに対し, メソッドの委譲機能を定義します.

== 使い方

オブジェクトに対して((|extend|))して使います.

g = Goo.new
  g.extend SingleForwardable
  g.def_delegator("@out", :puts)
  g.puts ...

== メソッド

--- SingleForwardable#def_singleton_delegators(accessor, *methods)

((|methods|))で渡されたメソッドのリストを((|accessor|))に委譲する
      ようにします.

--- SingleForwardable#def_singleton_delegator(accessor, method, ali = method)

--- SingleForwardable#def_delegators(accessor, *methods)

((|SingleForwardable#def_singleton_delegators|))の別名です.

--- SingleForwardable#def_delegator(accessor, method, ali = method)

((|SingleForwardable#def_singleton_delegator|))の別名です.
