Constructor Summary

IIOPListener(ORB orb)

Method Summary

Connection	accept() This call is an alternative to using set_handle() to initiate the callback-style of accepting new connections.
void	completed_data(Connection conn) The connection instance is returned to the Listener.
void	configure(org.apache.avalon.framework.configuration.Configuration configuration)
protected Connection	createServerConnection(java.net.Socket socket, boolean is_ssl) Template method to create a server-side ETF Connection.
void	destroy() The Listener is instructed to close its endpoint.
Profile	endpoint() Returns a copy of the profile describing the endpoint of this instance.
void	listen() It is possible that connection requests arrive after the initial creation of the Listener instance but before the conclusion of the configuration of the specific endpoint in this plugin.
void	set_handle(Handle up) This call establishes the link between the ORB (i.e. the Handle instance) and a server endpoint of the plugged-in transport.

Method Detail

configure

public void configure(org.apache.avalon.framework.configuration.Configuration configuration)
               throws org.apache.avalon.framework.configuration.ConfigurationException

Specified by:

configure in interface org.apache.avalon.framework.configuration.Configurable

Throws:

org.apache.avalon.framework.configuration.ConfigurationException

set_handle

public void set_handle(Handle up)

This call establishes the link between the ORB (i.e. the Handle instance) and a server endpoint of the plugged-in transport. All calls upwards into the ORB shall use the given instance.

Specified by:

set_handle in interface ListenerOperations

accept

public Connection accept()

This call is an alternative to using set_handle() to initiate the callback-style of accepting new connections. This call blocks until a client connects to the server. Then a new Connection instance is returned. The transport plug-in must ensure that a thread blocked in accept() returns when destroy() is called with a null object reference. The transport plug-in must raise the CORBA::BAD_INV_ORDER with minor code {TBD} if the ORB calls this operation and set_handle() has ever been called previously on the same listener instance.

Specified by:

accept in interface ListenerOperations

listen

public void listen()

It is possible that connection requests arrive after the initial creation of the Listener instance but before the conclusion of the configuration of the specific endpoint in this plugin. In order to provide a clear end of this configuration state, we added the listen() method. It is called by the ORB when it ready for incoming connection and thus signals the Listener instance to start processing the incoming connection requests. Therefore, a Listener instance shall not deliver incoming connections to the ORB before this method was called.

Specified by:

listen in interface ListenerOperations

destroy

public void destroy()

The Listener is instructed to close its endpoint. It shall no longer accept any connection requests and shall close all connections opened by it.

Specified by:

destroy in interface ListenerOperations

completed_data

public void completed_data(Connection conn)

The connection instance is returned to the Listener. It now shall signal any incoming data to the Handle.

Specified by:

completed_data in interface ListenerOperations

endpoint

public Profile endpoint()

Returns a copy of the profile describing the endpoint of this instance.

Specified by:

endpoint in interface ListenerOperations

createServerConnection

protected Connection createServerConnection(java.net.Socket socket,
                                            boolean is_ssl)
                                     throws java.io.IOException

Template method to create a server-side ETF Connection. This can be overridden by subclasses to pass a different kind of Connection up to the ORB.

Throws:

java.io.IOException
