我有投入数据生成模式的NetStream正确的......一切工作正常，我也得到将onSeekPoint（）事件时，我像做了以下内容：

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，而是让这一切在父类，我需要创建一个新的类，它也有将onSeekPoint客户端。它不工作。奇怪的是，调用onMetaData回调做......这件事情是这样的：

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:

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，也许有一些小问题，我missed-但真正吓到我了，是这完全正常工作......

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
}

我猜，如果它不破不解决它可能适用于这里，但是我有点担心，让一些code我不明白去了，还怕它可能回来咬我，当我最不经意的时候;）

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：

为什么不为seekPoints第二个例子中的工作？ 确定，则─为什么的确实的元数据第二个例子中的工作？ 为什么第三个例子解决一切？ Why doesn't the second example work for seekPoints? Ok then- why does the second example work for metaData? Why does the third example fix everything?

修改：如果现在还不清楚，不同类是正确的在不同的文件，等他们只是合并在这里的例子，使其更容易消化

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

在第二个例子中，你有这样的：

In your second example you have this:

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

但它不应该是这样的：

But shouldn't it be something like this:

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