Direct Known Subclasses:

QueuingAsyncSocketConnection

public abstract class AsyncSocketConnection
extends Object

Baseclass for handling async io. Its strongly recommended to use QueuingAsyncSocketConnection as this eases things.

Field Detail

readBuf

protected ByteBuffer readBuf

key

protected SelectionKey key

chan

protected SocketChannel chan

writePromise

protected Promise writePromise

writingBuffer

protected ByteBuffer writingBuffer

isClosed

protected boolean isClosed

myActor

protected Executor myActor

theExecutingThread

protected 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.
