Poller

public Poller()
       throws IOException

Throws:

IOException

Method Details

getKeyCount

public int getKeyCount()

getSelector

public Selector getSelector()

destroy

protected void destroy()

Destroy the poller.

add

public void add(NioEndpoint.NioSocketWrapper socketWrapper,
 int interestOps)

Add specified socket and associated pool to the poller. The socket will be added to a temporary array, and polled first after a maximum amount of time equal to pollTime (in most cases, latency will be much lower, however).

Parameters:

socketWrapper - to add to the poller

interestOps - Operations for which to register this socket with the Poller

events

public boolean events()

Processes events in the event queue of the Poller.

Returns:

true if some events were processed, false if queue was empty

register

public void register(NioEndpoint.NioSocketWrapper socketWrapper)

Registers a newly created socket with the poller.

Parameters:

socketWrapper - The socket wrapper

cancelledKey

public void cancelledKey(SelectionKey sk,
 SocketWrapperBase<NioChannel> socketWrapper)

run

public void run()

The background thread that adds sockets to the Poller, checks the poller for triggered events and hands the associated socket off to an appropriate processor as events occur.

Specified by:

run in interface Runnable

processKey

protected void processKey(SelectionKey sk,
 NioEndpoint.NioSocketWrapper socketWrapper)

processSendfile

public SendfileState processSendfile(SelectionKey sk,
 NioEndpoint.NioSocketWrapper socketWrapper,
 boolean calledByProcessor)

unreg

protected void unreg(SelectionKey sk,
 NioEndpoint.NioSocketWrapper socketWrapper,
 int readyOps)

reg

protected void reg(SelectionKey sk,
 NioEndpoint.NioSocketWrapper socketWrapper,
 int intops)

timeout

protected void timeout(int keyCount,
 boolean hasEvents)
