🎿 🤸🏿 🥐 Ruby-クラスメソッドのプロキシ 🌸 📒 🙏🏾

コード内でクラスメソッドをコーディング（ラップ）することが必要になる場合があります。

例：

それらをスレッドで実行する
前後にフィルターを掛ける
パフォーマンスを測定する

したがって、habrmanに関する情報を取得する特定のクラスがあるとします。

次のように使用します。

Copy Source | Copy HTML
info = Habr。新規（ 'tenkoff' ）
p info.get_rating
p info.get_posts

最も簡単な解決策は、クラスの新しいインスタンスをプロキシクラスに渡すことです。

Copy Source | Copy HTML
プロキシ=プロキシ。 new （ProxedClass.new）

これを行うには、 method_missingメソッドが必要です。

Copy Source | Copy HTML
クラスプロキシ
def 初期化（obj）
@ class = obj || 自己
終わり
def method_missing （名前、*引数、およびブロック）
p 「## {name}の前」
result = @ class .send name、* args、＆block
p 「## {name}の後」
結果
終わり
終わり

これで、以前のコードは次のように使用できます。

Copy Source | Copy HTML
info =プロキシ。 new （Habr。new（ 'tenkoff' ））
p info.get_rating
p info.get_posts

本当にしたい場合は、Proxyクラスを継承の基本クラスとして使用できます。そのためには、 method_addedメソッドが必要です（ここではgoogleする必要があります）。

Copy Source | Copy HTML
クラスプロキシ
def 初期化（obj = '' ）
@ class = obj || 自己
終わり
def method_missing （名前、*引数、およびブロック）
p 「## {name}の前」
result = @ class .send name、* args、＆block
p 「## {name}の後」
結果
終わり
def self .method_added（メソッド）
もしself .public_method_defined？方法
プライベートメソッド
終わり
終わり
終わり

クラスのメソッドがmethod_missingメソッドのラッパーに確実に収まるように、すべてのパブリックメソッドをプライベートにするprivateメソッドを使用します。

また、プロキシクラスを次のように変更して、基本クラスの適切な初期化に注意する必要があります。

Copy Source | Copy HTML
def initialize （ユーザー）
@user =ユーザー
@uid = get_uid
スーパー（自己）
終わり

実際、これはすべて黒魔術であり、人生のすべての場合に100％は機能しません。

それでは、どのように機能しますか
method_missing-このメソッドは、存在しないまたはアクセスできないクラスメソッドを要求するとトリガーされます。次の3つのパラメーターが必要です。
メソッド名
引数
ブロックする

次に、sendメソッドを使用して、任意のクラスのメソッドを呼び出すことができます。次に例を示します。

Copy Source | Copy HTML
irb（メイン）： 001 ： 0 > カーネル .send： print 、「hello world」
Hello world => nil

method_added-このメソッドは、新しいメソッドがクラスに追加された瞬間にトリガーされます。これは、記述した場所、つまり、 method_addedの後に他のメソッドがある場合は、それらもキャッチします。

したがって、method_missingを使用すると、存在しないまたはアクセスできないクラスメソッドをキャッチして、基本クラスからこのブラックマジックを継承する既存のクラスメソッドを作成できます。method_addedを使用して、新しいメソッドの追加を登録し、プライベートメソッド、したがってmethod_missingに入ることを保証します。

プロキシされたクラスが呼び出されるプログラムのコードを変更することなく、作業中のクラスに触れることなく、追加のロジックでそれらをラップできます。

Ruby-クラスメソッドのプロキシ
