Constructor Detail

UDPEndPoint

public UDPEndPoint(DatagramSocket socket)

create an endpoint on the given socket

Parameters:

socket - - a UDP datagram socket

UDPEndPoint

public UDPEndPoint(InetAddress localAddress)
            throws SocketException,
                   UnknownHostException

bind to any local port on the given host address

Parameters:

localAddress -

Throws:

SocketException

UnknownHostException

UDPEndPoint

public UDPEndPoint(InetAddress localAddress,
                   int localPort)
            throws SocketException,
                   UnknownHostException

Bind to the given address and port

Parameters:

localAddress -

localPort - - the port to bind to. If the port is zero, the system will pick an ephemeral port.

Throws:

SocketException

UnknownHostException

UDPEndPoint

public UDPEndPoint(int localPort)
            throws SocketException,
                   UnknownHostException

bind to the default network interface on the machine

Parameters:

localPort - - the port to bind to. If the port is zero, the system will pick an ephemeral port.

Throws:

SocketException

UnknownHostException

UDPEndPoint

public UDPEndPoint()
            throws SocketException,
                   UnknownHostException

bind to an ephemeral port on the default network interface on the machine

Throws:

SocketException

UnknownHostException

Method Detail

start

public void start(boolean serverSocketModeEnabled)

start the endpoint. If the serverSocketModeEnabled flag is true, a new connection can be handed off to an application. The application needs to call #accept() to get the socket

Parameters:

serverSocketModeEnabled -

start

public void start()

stop

public void stop()

getLocalPort

public int getLocalPort()

Returns:

the port which this client is bound to

getLocalAddress

public InetAddress getLocalAddress()

Returns:

Gets the local address to which the socket is bound

addSession
