onSeekPoint 怪异

问题描述

我有一个正确进入数据生成模式的 NetStream...一切正常，当我执行以下操作时，我会收到 onSeekPoint() 事件:

I have a NetStream which is put into data generation mode properly... everything works fine and I get onSeekPoint() events when I do something like the following:

示例 1

public function setupStream() {
     netStream.client = {};
     netStream.client.onSeekPoint = this.onSeekPoint;
     netStream.client.onMetaData = this.onMetaData;
}

public function onSeekPoint(... args) {...}
public function onMetaData(... args) {...}

然而，我需要为客户端创建一个新类，而不是将其全部保留在该父类中，该类也具有该 onSeekPoint.它不起作用.奇怪的是，onMetaData 回调确实……是这样的:

However, instead of keeping it all in that parent class, I need to create a new class for the client which also has that onSeekPoint. It doesn't work. Strangely, the onMetaData callback does... it's something like this:

示例 2

package {
   public class CustomClient {
       public function CustomClient() {
       }
       public function onSeekPoint(... args) {...}
       public function onMetaData(... args) {...}
   }
}

public function setupStream() {
   var myClient:CustomClient = new CustomClient();
   netStream.client = CustomClient;
}

我想可能是我遗漏了一些小问题 - 但真正让我感到害怕的是，它完全正常工作......

I thought that maybe there's some small issue I missed- but what's really freaking me out, is that this fully works properly...

示例 3

package {
   public class CustomClient {
       public function CustomClient() {
       }
       public function onSeekPoint(... args) {...}
       public function onMetaData(... args) {...}
   }
}

public function setupStream() {
   var myClient:CustomClient = new CustomClient();
   netStream.client = {};
   netStream.client.onSeekPoint = myClient.onSeekPoint;
   netStream.client.onMetaData = myClient.onMetaData
}

我想如果它没有坏就不要修复它"可能适用于这里，但我有点担心让一些我不理解的代码消失，并且担心当我最不希望它;)

I guess "if it ain't broke don't fix it" might apply here, but I'm a little worried letting some code I don't understand go, and afraid it might come back to bite me when I least expect it ;)

我的问题是:

1. 为什么第二个示例不适用于 seekPoints?
2. 好的 - 为什么 第二个示例适用于元数据?
3. 为什么第三个示例可以解决所有问题?

1. Why doesn't the second example work for seekPoints?
2. Ok then- why does the second example work for metaData?
3. Why does the third example fix everything?

编辑:如果不清楚，不同的类在不同的文件中是正确的，等等.它们只是在这里的例子中组合起来，以便于理解

EDIT: In case it's unclear, the different classes are correctly in separate files, etc. They're just combined in the examples here to make it easier to digest

推荐答案

在你的第二个例子中，你有这个:

In your second example you have this:

var myClient:CustomClient = new CustomClient();
netStream.client = CustomClient;

但不应该是这样的:

var myClient:CustomClient = new CustomClient();
netStream.client = myClient;
