Method Summary

Modifier and Type	Method	Description
protected void	accept(int acceptorID)
void	close()	Performs the activities needed to close the network communication (for example, to stop accepting network connections).
protected void	doStart()	Starts the managed lifecycle beans in the order they were added.
protected void	doStop()	Stops the managed lifecycle beans in the reverse order they were added.
int	getLocalPort()
Object	getTransport()	Get the underlying socket, channel, buffer etc. for the connector..
boolean	isOpen()	A Connector may be opened and not started (to reserve a port) or closed and running (to allow graceful shutdown of existing connections)

Constructor Details

DatagramServerConnector

public DatagramServerConnector(Server server,
 ConnectionFactory... factories)

DatagramServerConnector

public DatagramServerConnector(Server server,
 Executor executor,
 Scheduler scheduler,
 ByteBufferPool bufferPool,
 ConnectionFactory... factories)

Method Details

getLocalPort

public int getLocalPort()

Specified by:

getLocalPort in interface NetworkConnector

Overrides:

getLocalPort in class AbstractNetworkConnector

Returns:

The actual port the connector is listening on, or -1 if it has not been opened, or -2 if it has been closed.

isOpen

public boolean isOpen()

Description copied from interface: NetworkConnector

A Connector may be opened and not started (to reserve a port) or closed and running (to allow graceful shutdown of existing connections)

Returns:

True if the connector is Open.

doStart

protected void doStart()
                throws Exception

Description copied from class: ContainerLifeCycle

Starts the managed lifecycle beans in the order they were added.

Overrides:

doStart in class AbstractNetworkConnector

Throws:

Exception - If there was a problem starting. Will cause a transition to FAILED state

open

public void open()
          throws IOException

Description copied from interface: NetworkConnector

Performs the activities needed to open the network communication (for example, to start accepting incoming network connections).

Implementation must be idempotent.

Specified by:

open in interface NetworkConnector

Overrides:

open in class AbstractNetworkConnector

Throws:

IOException - if this connector cannot be opened

See Also:

• NetworkConnector.close()

openDatagramChannel

protected DatagramChannel openDatagramChannel()
                                       throws IOException

Throws:

IOException

setIdleTimeout

public void setIdleTimeout(long idleTimeout)

Description copied from class: AbstractConnector

Sets the maximum Idle time for a connection, which roughly translates to the Socket.setSoTimeout(int) call, although with NIO implementations other mechanisms may be used to implement the timeout.

The max idle time is applied:

• When waiting for a new message to be received on a connection
• When waiting for a new message to be sent on a connection

This value is interpreted as the maximum time between some progress being made on the connection. So if a single byte is read or written, then the timeout is reset.

Overrides:

setIdleTimeout in class AbstractConnector

Parameters:

idleTimeout - the idle timeout

doStop

protected void doStop()
               throws Exception

Description copied from class: ContainerLifeCycle

Stops the managed lifecycle beans in the reverse order they were added.

Overrides:

doStop in class AbstractNetworkConnector

Throws:

Exception - If there was a problem stopping. Will cause a transition to FAILED state

close

public void close()

Description copied from interface: NetworkConnector

Performs the activities needed to close the network communication (for example, to stop accepting network connections).

Once a connector has been closed, it cannot be opened again without first calling LifeCycle.stop() and it will not be active again until a subsequent call to LifeCycle.start().

Implementation must be idempotent.

Specified by:

close in interface AutoCloseable

Specified by:

close in interface Closeable

Specified by:

close in interface NetworkConnector

Overrides:

close in class AbstractNetworkConnector

getTransport

public Object getTransport()

Description copied from interface: Connector

Get the underlying socket, channel, buffer etc. for the connector..

Returns:

the underlying socket, channel, buffer etc. for the connector.

accept

protected void accept(int acceptorID)

Specified by:

accept in class AbstractConnector

newEndPoint

protected EndPoint newEndPoint(DatagramChannel channel,
 ManagedSelector selector,
 SelectionKey selectionKey)

newConnection

protected Connection newConnection(EndPoint endpoint)
