Direct Known Subclasses:

HandshakeablePerpetualSocketAcceptor

public class HandshakeableSocketAcceptor
extends TimeableConnection

This acceptor works similar to SocketAcceptor except for the addition of adding handshaking capability.

open

public void open(int backlog)
          throws java.io.IOException

Throws:

java.io.IOException

accept

public void accept(HandshakeableSocketHandler socketHandler)

Accepts a connection synchronously and hands it over to the handler for processing. The caller of this method will wait until data processing is finished before regaining control. This is meant for occassions such as HTTP requests where retrieval of data occurs once and data is returned for further processing.

Notice that the server socket is NOT closed after handler returns. The connection should be closed explicitly by the application or inside the handler.

aaccept

public void aaccept(HandshakeableSocketHandler socketHandler)

The asynchronous version of the accept method. The connection is passed to a thread for execution. The server socket is not automatically closed at the end. You must explicitly close the server socket when you're done. Failure to do so will result in a port that's binded until the end of the application.

close

public void close()

Closes the server socket and unbind from the port. The close does NOT close all the currently accepted (and processing) handlers. It only close the server socket so that additional connections are refused. It is up to you to keep track of the handlers and also close them if you want all connections to be shutdown.

getConnectionModel

public ConnectionModel getConnectionModel()

setConnectionModel

public void setConnectionModel(ConnectionModel connectionModel)
                        throws java.io.IOException

use a new connection model. The current server socket will be closed and then a new server socket will be created. Once a connection model is passed in through the constructor, it's not usually changed. However, the Acceptor can be reused in this way if the situation requires it.

Throws:

java.io.IOException

setConnectionModel

public void setConnectionModel(ConnectionModel connectionModel,
                      int backlog)
                        throws java.io.IOException

sets the connection model plus the backlog for the port that the listener should bind to and listen on.

Throws:

java.io.IOException
