TracePoint
# defined _ class -> Class | module (15351.0) -
メソッドを定義したクラスかモジュールを返します。
...す。
//emlist[例][ruby]{
class C; def foo; end; end
trace = TracePoint.new(:call) do |tp|
p tp.defined_class # => C
end.enable do
C.new.foo
end
//}
メソッドがモジュールで定義されていた場合も(include に関係なく)モジュー
ルを返します。
//emlist[例][ruby]......{
module M; def foo; end; end
class C; include M; end;
trace = TracePoint.new(:call) do |tp|
p tp.defined_class # => M
end.enable do
C.new.foo
end
//}
[注意] 特異メソッドを実行した場合は TracePoint#defined_class は特異クラ
スを返します。また、Kernel.#set_trace_fun......スではなく元のクラスを返します。
//emlist[例][ruby]{
class C; def self.foo; end; end
trace = TracePoint.new(:call) do |tp|
p tp.defined_class # => #<Class:C>
end.enable do
C.foo
end
//}
Kernel.#set_trace_func と TracePoint の上記の差分に注意して
ください。

File.superclass #=> IO
IO.superclass #=> Object
class Foo; end
class Bar < Foo; end
Bar.superclass #=> Foo
Object.superclass #=> BasicObject

ARGF
. class # internal _ encoding -> Encoding | nil (15313.0) -
ARGF から読み込んだ文字列の内部エンコーディングを返します。 内部エンコーディングが指定されていない場合は nil を返します。
...nil を返します。
まだ読み込み処理を始めていない場合は Encoding.default_external を返します。
ARGF.class#set_encoding で設定します。
例:
# $ ruby -Eutf-8 test.rb
# test.rb
ARGF.internal_encoding # => #<Encoding:UTF-8>
ARGF.set_encoding('u......tf-8','ascii')
ARGF.internal_encoding # => #<Encoding:US-ASCII>
例:
ARGF.binmode
ARGF.internal_encoding # => nil
@see IO, ARGF.class#external_encoding... -
Class
# inherited(subclass) -> () (15237.0) -
クラスのサブクラスが定義された時、新しく生成されたサブクラスを引数 にインタプリタから呼び出されます。このメソッドが呼ばれるタイミングは クラス定義文の実行直前です。
...ubclass プログラム内で新たに定義された自身のサブクラスです。
//emlist[例][ruby]{
class Foo
def Foo.inherited(subclass)
puts "class \"#{self}\" was inherited by \"#{subclass}\""
end
end
class Bar < Foo
puts "executing class body"
end
# => class "Foo" was inherit......ed by "Bar"
# executing class body

# singleton _ class -> Class (12339.0) -
レシーバの特異クラスを返します。 まだ特異クラスがなければ、新しく作成します。
...が nil か true か false なら、それぞれ NilClass, TrueClass,
FalseClass を返します。
@raise TypeError レシーバが Integer、Float、Symbol の場合に発生します。
//emlist[][ruby]{

self に特異メソッド name を定義します。
...String または Symbol で指定します。
@param method Proc、Method あるいは UnboundMethod の
いずれかのインスタンスを指定します。
@return メソッド名を表す Symbol を返します。
