なんかPerlのblessっぽい。
JavaScriptのnewって本当にいらない子？(http://d.hatena.ne.jp/jdg/20090706/1246840565)
というよりperlのnewっぽい。なぜか。
classでクラスを定義してnewでインスタンスを生成する言語を「一般的オブジェクト指向言語」とすると、
つまり、javascriptでnewを（直接）使わず、class（のようなもの）を作ればperlっぽくなる。
オブジェクトを作る。オブジェクトを作るには3つの動作が必要である。
通常は言語仕様でこれらを行う"new"という命令が用意されている。しかし、必ずしも必要な物ではない。perlでは言語仕様としてはnewが用意されていない。new関数が存在するのはコーディング規約に従っているからに過ぎない。代わりにblessが用意されている。なぜこのようになっているのか。理由はいたって簡単だ。perlのオブジェクトの実態はリファレンスだ。初期化を行うコンストラクタはどの道定義せねばならない。だから必要なのはリファレンスとパッケージを結びつけるおまじないblessだけだ。コンストラクタで好きなリファレンスを用意し、好きなように初期化してblessすればよい。コンストラクタの名前はコーディング規約でnewと決めた。一方javascriptはnewを用意した。{}でオブジェクトは作れるし、どの道コンストラクタは作る必要があるのに。
オブジェクトとクラスを結びつける。しかし、javascriptはクラスを持たないので必要はない。代わりに必要なのは、継承元との結びつき、プロトタイプチェーンの構築だ。
既存のクラスの性質や振る舞いを流用する。default状態を与える。一般的オブジェクト指向言語ではクラス定義時に継承元となるクラスを指定する。javascriptではクラスの代わりにオブジェクトを指定する。
クラスとはオブジェクトの性質・振る舞いの定義だ。しかし、ダック・タイピングではオブジェクトの性質や振る舞いはオブジェクトの持つメンバにより決まるため、そのような環境ではオブジェクトに初期値と継承関係を与えるのが主な仕事となる。
コンストラクタはオブジェクトの初期化を行う。javascriptではクラスがないため継承とコンストラクタによりオブジェクトが初期化される。
var object = function(o) { var F = function() {}; F.prototype = o.prototype; return new F; };JavaScriptのnewって本当にいらない子？(http://d.hatena.ne.jp/jdg/20090706/1246840565)
個人的には
var object = function(o) { var F = function() {}; F.prototype = o; return new F; };
で良いんじゃね？って思う。
更に、コレでは初期化しないから
var object = function(o, n) { var F = function() {}; F.prototype = o; f = new F; if (n) for (var i in n) f[i] = n[i]; return f; };
みたいな。
さらにせっかくだからメソッドにして
var object = function(o, n) { var F = function() {}; F.prototype = o; f = new F; if (not f.inherit) f.inherit = function(n) {object(this, n)}; if (n) for (var i in n) f[i] = n[i]; return f; };
とか。
ところでサー
javascriptってラッパー作りやすくていいよね。
名前を変えずにラップ出来るから好き。
クラスもインスタンスもメソッドも関数もオーバーライドしてラップして、好き勝手出来るから好き。
(function(){ var origin = hoge.prototype.foo; hoge.prototype.foo = function(){ ... }; hoge.prototype.foo.origin = origin; })();
perlはオーバーライドできるけど、元のメソッド呼べなくなる。すべてのインスタンスに影響する（たしか）。チョイめんどい。
use hoge; package hoge; sub foo { ... } package main; ...
他の言語では、どんな技がありますか？
[追記]
\&hoge::foo で元のコードのリファレンス取れたっけ？
すっかり忘れてる。

javascriptでスーパークラスのメソッドを簡単に呼び出したかった。それだけだった。
var Class = inherit(SuperClass, {hoge: ...});
作ったクラスはprototypeに、第二引数のオブジェクトがコピーされたスーパークラスのインスタンスを持つ。
第一引数がnullだと、スーパークラスにObjectを用いる。つまり、
var Class = inherit(null, {hoge: ...});
は
var Class = inherit(Object, {hoge: ...});
と同等となる。
また、第一引数が"prototype"をメンバに持たない普通のオブジェクト、つまり、
var Class = inherit({hoge: ...});
だと
var Class = inherit(Object, {hoge: ...});
と同等となる。
var obj = new Class({hoge: ...});
でインスタンスを作ると、引数のオブジェクトのコピーを持つオブジェクトとなる。
また、メソッド"initialize"が自動的に実行される。
ただし、コンストラクタに引数を渡さなかった場合は、initializeは実行されない。
this.superapply(arguments);
としてスーパークラスのメソッドを呼べる。第一引数は呼び出すメソッドの引数の配列とする。
このとき、呼び出し側のメソッドはコンストラクタやinheritでオーバーライドしたメソッドでなくてはならない。これは呼び出し側のメソッド名を記録する必要があるためである。
そうでない場合は第二引数にメソッド名を渡す必要がある。
var obj = new Class({}); obj.foo = function(){ this.superapply(arguments); // X this.superapply(arguments, "foo"); // O };
