Class ServerAcseSap

java.lang.Object

com.beanit.josistack.ServerAcseSap

All Implemented Interfaces:

TConnectionListener

public final class ServerAcseSap
extends java.lang.Object
implements TConnectionListener

This class implements the server Service Access Point (SAP) for the Application Control Service Element (ACSE) protocol as defined by ISO 8650 or ITU X.217/X.227. The ACSE provides services for establishing and releasing application-associations. The class also realizes the lower ISO Presentation Layer as defined by ISO 8823/ITU X226 and the ISO Session Layer as defined by 8327/ITU X.225.

Constructor Detail

ServerAcseSap

public ServerAcseSap(int port,
                     int backlog,
                     java.net.InetAddress bindAddr,
                     AcseAssociationListener associationListener)

Use this constructor to create a server ACSE SAP that listens on a fixed port.

Parameters:

port - the local port listen on

backlog - the backlog

bindAddr - the InetAddress to bind to

associationListener - the AssociationListener that will be notified when remote clients have associated. Once constructed the AcseSAP contains a public TSAP that can be accessed to set its configuration.

ServerAcseSap

public ServerAcseSap(int port,
                     int backlog,
                     java.net.InetAddress bindAddr,
                     AcseAssociationListener associationListener,
                     javax.net.ServerSocketFactory serverSocketFactory)

Use this constructor to create a server ACSE SAP that listens on a fixed port. The server socket is created with the given socket factory.

Parameters:

port - the local port listen on

backlog - the backlog

bindAddr - the InetAddress to bind to

associationListener - the AssociationListener that will be notified when remote clients have associated. Once constructed the AcseSAP contains a public TSAP that can be accessed to set its configuration.

serverSocketFactory - the server socket factory to create the socket

Method Detail

startListening

public void startListening()
                    throws java.io.IOException

Start listening for incoming connections. Only for server SAPs.

Throws:

java.io.IOException - if an error occures starting to listen

stopListening

public void stopListening()

serverStoppedListeningIndication

public void serverStoppedListeningIndication(java.io.IOException e)

This function is internal and should not be called by users of this class.

Specified by:

serverStoppedListeningIndication in interface TConnectionListener

Parameters:

e - The IOException caught form ServerSocket.accept()

connectionIndication

public void connectionIndication(TConnection tConnection)

This function is internal and should not be called by users of this class.

Specified by:

connectionIndication in interface TConnectionListener
