Class ServerAcseSAP

java.lang.Object
  org.openiec61850.jmms.iso.acse.ServerAcseSAP

All Implemented Interfaces:

TConnectionListener

public 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:

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.

Parameters:

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.

Method Detail
