ReceiveActorのコード複製を減らす方法

Question

私は、Become（）メソッドによって切り替えられた、切り替え可能な振る舞いを持つReceive Actorを持っています。子アクターを監視するには、すべての状態メソッドに対してReceive < Terminated>呼び出しを追加する必要があります。例えば

、私の代わりに、あなたのようにTerminatedの型を取るプライベートメソッドを作成することができ、あなたのアクションを実行するためにラムダを使用している

public class SomeActor : ReceiveActor 
{ 
    public SomeActor() 
    { 
     // create child actors 
     Become(Ready); 
    } 

    private void Ready() 
    { 
     Receive<InitMessage>(m => 
     { 
      Become(Working1); 
     }); 

     Receive<Terminated>(m => 
     { 
      // duplicated termination stuff 
      Become(Terminated); 
     }); 
    } 

    private void Working1() 
    { 
     Receive<InitMessage>(m => 
     { 
      Become(Working2); 
     }); 

     Receive<Terminated>(m => 
     { 
      // duplicated termination stuff 
      Become(Terminated); 
     }); 
    } 

    private void Working2() 
    { 
     Receive<InitParcerMessage>(m => 
     { 
      Become(Working1); 
     }); 

     Receive<Terminated>(m => 
     { 
      // duplicated termination stuff 
      Become(Terminated); 
     }); 
    } 

    private void Terminated() 
    { 
     // do some stuff 
    } 
}

準備、Working1とWorking2メソッドに貼り付けする必要がありますパラメータを入力し、ReceiveのアクションでMethodGroupを使用してください。

public class SomeActor : ReceiveActor 
{ 
    public SomeActor() 
    { 
     // create child actors 
     Become(Ready); 
    } 

    private void Ready() 
    { 
     Receive<InitMessage>(m => 
     { 
      Become(Working1); 
     }); 

     ConfigureReceive(); 
    } 

    private void Working1() 
    { 
     Receive<InitMessage>(m => 
     { 
      Become(Working2); 
     }); 

     ConfigureReceive(); 
    } 

    private void Working2() 
    { 
     Receive<InitParcerMessage>(m => 
     { 
      Become(Working1); 
     }); 

     ConfigureReceive(); 
    } 

    private void Terminated() 
    { 
     // do some stuff 
    } 

    private void ConfigureReceive() 
    { 
     // Register Receive actors here 
     Receive<Terminated>(p => HandleTermination(p)); 
    } 

    // Here's our method to perform the same job with our Terminated parameter 
    private void HandleTermination(Terminated termination) 
    { 
     // Call our Become method 
     Become(Terminated); 
    } 
}
