问题描述
我有一个Scala / Java OpenGL应用程序，我在其中使用Akka框架。目前，我的OpenGL线程独立于actor系统，因此我可以保证对OpenGL函数的调用始终来自单个线程。这很重要，否则OpenGL会抱怨。
I have a Scala/Java OpenGL application in which I use the Akka framework. At the moment, my OpenGL thread is independent from the actor system so I can guarantee calls to OpenGL functions always come from a single thread. This is important, otherwise OpenGL will complain.
到目前为止，我不得不将OpenGL线程中的消息发送给系统中的actor，这非常有效。我现在面临着以相反的方式发送消息的需要，但当然我不能简单地将OpenGL放在一个actor中，因为这会破坏它从单个线程运行的要求。
Until now, I had to send messages from the OpenGL thread to actors in the system and this works pretty well. I am now faced with the need to send messages the other way around, but of course I cannot simply put the OpenGL in an actor as this will break the requirement that it runs from a single thread.
另一种方法是手动使用队列和锁来进行actor和OpenGL线程之间的通信，但是我想知道是否有办法将OpenGL调用放在一个特殊的Actor中。给予Akka保证在单个线程中运行。
An alternative would be to use a queue and a lock manually for the communication between actors and the OpenGL thread, but I'd like to know if there's a way to place OpenGL calls in a special Actor that would be given a guarantee by Akka to run in a single thread.

推荐答案
您可以使用 PinnedDispatcher 为每个actor使用单个线程。根据文档：
You can use a single thread per actor using a PinnedDispatcher. According to the doc:
