Constructor Detail

DefaultDatagramEngine

public DefaultDatagramEngine(org.slf4j.Logger log,
                     ExecutorService es,
                     int localPort,
                     int numSocketHandlers)
                      throws SocketException

Constructor that creates a 1 or more socket handlers.

Parameters:

log - logger

es - executor service

localPort - local port to bind socket (0 for dynamic port allocation)

numSocketHandlers - number of socket handlers when allocating dynamic socket ports (localPort is 0);

Throws:

SocketException - if there is a problem creating the socket

Method Detail

setListener

public void setListener(DatagramEngine.Listener listener)

Description copied from interface: DatagramEngine

Allows the setting of the engine listener. All engine implementations need to save the listener.

Specified by:

setListener in interface DatagramEngine

Parameters:

listener - engine listener

start

public void start()

Description copied from interface: DatagramEngine

Starts the engine.

Specified by:

start in interface DatagramEngine

stop

public void stop()

Description copied from interface: DatagramEngine

Stops the engine. Engine implementations should shutdown all resources, worker threads, etc.

Specified by:

stop in interface DatagramEngine

send

public void send(byte[] payload,
        InetSocketAddress address)

Description copied from interface: DatagramEngine

Main entry point to write the payload in a new datagram.

Specified by:

send in interface DatagramEngine

Parameters:

payload - datagram payload

address - socket address to send payload

isStarted

public boolean isStarted()

getLocalPortBindings

public int[] getLocalPortBindings()
