Class IdleTimeout

java.lang.Object

com.aspectran.utils.timer.IdleTimeout

public abstract class IdleTimeout
extends Object

This class is a clone of org.eclipse.jetty.io.IdleTimeout

An Abstract implementation of an Idle Timeout.

This implementation is optimised that timeout operations are not cancelled on every operation. Rather timeout are allowed to expire and a check is then made to see when the last operation took place. If the idle timeout has not expired, the timeout is rescheduled for the earliest possible time a timeout could occur.

Constructor Details

IdleTimeout

public IdleTimeout(Scheduler scheduler)

Parameters:

scheduler - A scheduler used to schedule checks for the idle timeout

Method Details

getScheduler

public Scheduler getScheduler()

getIdleFor

public long getIdleFor()

Returns:

the period of time, in milliseconds, that this object was idle

getIdleTimeout

public long getIdleTimeout()

Returns:

the idle timeout in milliseconds

See Also:

• setIdleTimeout(long)

setIdleTimeout

public void setIdleTimeout(long idleTimeout)

Sets the idle timeout in milliseconds.

A value that is less than or zero disables the idle timeout checks.

Parameters:

idleTimeout - the idle timeout in milliseconds

See Also:

• getIdleTimeout()

notIdle

public void notIdle()

This method should be called when non-idle activity has taken place.

onOpen

public void onOpen()

onClose

public void onClose()

checkIdleTimeout

protected long checkIdleTimeout()

onIdleExpired

protected abstract void onIdleExpired(TimeoutException timeout)

This abstract method is called when the idle timeout has expired.

Parameters:

timeout - a TimeoutException

isOpen

public abstract boolean isOpen()

This abstract method should be called to check if idle timeouts should still be checked.

Returns:

true if the entity monitored should still be checked for idle timeouts
