Class IdleTimeout

  • public abstract class IdleTimeout
extends java.lang.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.

      • 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

        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

        getIdleTimeout()

      • notIdle

        public void notIdle()
        This method should be called when non-idle activity has taken place.

        public void onOpen()

      • onClose

        public void onClose()

      • checkIdleTimeout

      • onIdleExpired

        protected abstract void onIdleExpired​(java.util.concurrent.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
