acceptAndOpen

public StreamConnection acceptAndOpen()
                               throws IOException

Returns a GenericConnection that represents a server side socket connection

Specified by:

acceptAndOpen in interface StreamConnectionNotifier

Returns:

a socket to communicate with a client.

Throws:

IOException - if an I/O error occurs when creating the input stream.

close

public void close()
           throws IOException

Close the connection.

IOException - if an I/O error occurs when closing the connection.

getLocalAddress

public String getLocalAddress()
                       throws IOException

Description copied from interface: ServerSocketConnection

Gets the local address to which the socket is bound.

The host address(IP number) that can be used to connect to this end of the socket connection from an external system. Since IP addresses may be dynamically assigned, a remote application will need to be robust in the face of IP number reasssignment.

The local hostname (if available) can be accessed from System.getProperty("microedition.hostname")

Specified by:

getLocalAddress in interface ServerSocketConnection

Returns:

the local address to which the socket is bound.

Throws:

IOException - if the connection was closed
