AsyncSocketChannel

abstract class AsyncSocketChannel extends AutoCloseable

An asynchronous channel for reading, writing, and manipulating a TCP socket.

On the JVM this is a wrapper around java.nio.channels.AsynchronousSocketChannel (class available since Java 7 for doing async I/O on sockets).

Example

 val asyncSocketChannel = AsyncSocketChannel()
 val connectF = asyncSocketChannel.connect(new InetSocketAddress("google.com", 80))
 val bytes = ByteBuffer.wrap("Hello world!".getBytes("UTF-8"))
 val writeF = connectF.flatMap(_ => asyncSocketChannel.write(bytes, None))
 writeF.onComplete {
   case Success(nr) =>
     println(f"Bytes written: $nr%d")
  case Failure(exc) =>
     println(s"ERR: $exc")
 }

Value members

Abstract methods

Connects this channel.

Value Params

cb: is the callback to be called with the result, once this asynchronous operation is complete
remote: the remote address to which this channel is to be connected

Asks the socket address that this channel's socket is bound to

Reads a sequence of bytes from this channel into the given buffer

Value Params

cb: is the callback to be called with the result, once this asynchronous operation is complete . For this method it signals the number of bytes read or -1 if no bytes could be read because the channel has reached end-of-stream
dst: is the buffer holding the bytes read on completion
timeout: an optional maximum time for the I/O operation to complete

Asks the remote address to which this channel's socket is connected

Indicates that this channel will not read more data - end-of-stream indication

Indicates that this channel will not write more data - end-of-stream indication

Writes a sequence of bytes to this channel from the given buffer

Value Params

cb: is the callback to be called with the result, once this asynchronous operation is complete . For this method it signals the number of bytes that were written
src: is the buffer holding the sequence of bytes to write
timeout: an optional maximum time for the I/O operation to complete
