Field Detail
acceptor
protected Acceptor acceptor(Code)
The primary acceptor of this listener.



configuration
protected org.jacorb.config.Configuration configuration(Code)
The configuration.



logger
protected Logger logger(Code)
The logger.



orb
protected ORB orb(Code)
The ORB.



profile
protected Profile profile(Code)
The profile of this listener's endpoint.



up
protected org.omg.ETF.Handle up(Code)
Reference to the ORB, for delivering incoming connections via upcalls.





Method Detail
accept
public Connection accept()(Code)
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.



completed_data
public void completed_data(Connection conn)(Code)
The connection instance is returned to the Listener. It now shall signal any incoming data to the Handle.



configure
public void configure(Configuration config) throws ConfigurationException(Code)



deliverConnection
protected void deliverConnection(Connection connection)(Code)
Method the Acceptor implementation should call to pass an opened connection to the ORB.



destroy
public void destroy()(Code)
The Listener is instructed to close its endpoint. It shall no longer accept any connection requests and shall close all connections opened by it.



endpoint
public Profile endpoint()(Code)
Returns a copy of the profile describing the endpoint of this instance.



listen
public void listen()(Code)
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.



set_handle
public void set_handle(Handle up)(Code)
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.
