Method Detail

checkPermission

protected void checkPermission(int port)

open

public void open(String name,
                 int mode,
                 boolean timeouts)
          throws IOException

Open the connection

Specified by:

open in class ConnectionBase

Parameters:

name - the target for the connection

writeable - a flag that is true if the caller expects to write to the connection.

timeouts - A flag to indicate that the called wants timeout exceptions

The name string for this protocol should be: "

Throws:

ConnectionNotFoundException - If the connection cannot be found.

IOException - If some other kind of I/O error occurs.

open

public void open()
          throws IOException

Open the connection to an arbitrary system selected port and address

Throws:

IOException

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.

Specified by:

close in interface Connection

Overrides:

close in class GeneralBase

Throws:

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

FilterOutputStream.flush(), FilterOutputStream.out

getLocalAddress

public String getLocalAddress()
                       throws IOException

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 reassignment.

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

See Also:

SocketConnection

getLocalPort

public int getLocalPort()
                 throws IOException

Returns the local port to which this socket is bound.

Specified by:

getLocalPort in interface ServerSocketConnection

Returns:

the local port number to which this socket is connected.

Throws:

IOException - if the connection was closed

SocketConnection
