Method Detail

accept

DTLSSocket accept()
           throws IOException

Listens for a connection to be made to this socket and accepts it. The method blocks until a connection is made.

A new Socket s is created and, if there is a security manager, the security manager's checkAccept method is called with s.getInetAddress().getHostAddress() and s.getPort() as its arguments to ensure the operation is allowed. This could result in a SecurityException.

Returns:

the new Socket

Throws:

IOException - if an I/O error occurs when waiting for a connection.

SecurityException - if a security manager exists and its checkAccept method doesn't allow the operation.

SocketTimeoutException - if a timeout was previously set with setSoTimeout and the timeout has been reached.

getLocalAddress

InetAddress getLocalAddress()

Returns the local address of this server socket.

If the socket was bound prior to being closed, then this method will continue to return the local address after the socket is closed.

If there is a security manager set, its checkConnect method is called with the local address and -1 as its arguments to see if the operation is allowed. If the operation is not allowed, the loopback address is returned.

Returns:

the address to which this socket is bound, or the loopback address if denied by the security manager, or null if the socket is unbound.

getLocalPort

int getLocalPort()

Returns the port number on which this socket is listening.

If the socket was bound prior to being closed, then this method will continue to return the port number after the socket is closed.

Returns:

the port number to which this socket is listening or -1 if the socket is not bound yet.
