所有已实现的接口:

Closeable, AutoCloseable, AsynchronousByteChannel, AsynchronousChannel, Channel, CompletionHandler<Integer,Void>, NetworkChannel

public class TlsAsynchronousSocketChannel
extends AsynchronousSocketChannel
implements CompletionHandler<Integer,Void>

FilterInputStream-esque byte channel that decrypts incoming packets. We proxy calls to the read method from the caller. We replace the provided completion handler with our own handler that decrypts the incoming message and an then delegates to the original handler.

Note: This implementation does not support attachments for reads. They are not used in AsyncMessageReader which this class is in direct support of.
