Method Detail

onLoop

protected void onLoop()

Description copied from class: SelectorManager

This method is to be implemented by a subclass to do some task each loop.

Overrides:

onLoop in class SelectorManager

invoke

public void invoke(Runnable d)

Description copied from class: SelectorManager

This method schedules a runnable task to be done by the selector thread during the next select() call. All operations which modify the selector should be done using this method, as they must be done in the selector thread.

Overrides:

invoke in class SelectorManager

Parameters:

d - The runnable task to invoke

addStat

public void addStat(String s,
                    long time)

printStats

public void printStats()

executeTask

protected boolean executeTask(TimerTask next)

Overrides:

executeTask in class SelectorManager

doSelections

protected void doSelections()
                     throws IOException

Overrides:

doSelections in class SelectorManager

Throws:

IOException

doInvocations

protected void doInvocations()

Method which invokes all pending invocations. This method should *only* be called by the selector thread.

Overrides:

doInvocations in class SelectorManager

doInvocations2

protected void doInvocations2()
