Direct Known Subclasses:
QueuingAsyncSocketConnection
public abstract class AsyncSocketConnection
extends java.lang.Object
Baseclass for handling async io. Its strongly recommended to use QueuingAsyncSocketConnection as this eases things.

    • theExecutingThread

      protected java.lang.Thread theExecutingThread
      writes given buffer content. In case of partial write, another write is enqueued internally. once the write is completed, the returned promise is fulfilled. the next write has to wait until the future has completed, else write order might get mixed up. Better use write* methods of QueuingAsyncSocketConnection as these will write to a binary queue which is read+sent behind the scenes in parallel.
