Class TimerEvent


  • public class TimerEvent
    extends java.lang.Object
    Represents a particular observable event. We are mostly interested in measuring how long an operation takes. An operation is typically represented by a Timer, and then the timer is used to generate a TimerEvent at the entry to and exit from the operation.

    Note that this class can also be used as a base class, in case there is a need to attach extra information to a TimerEvent.

    All access to this class is unsynchronized. This class must be used either as an immutable (no calls to update), or access must be restricted to a single thread (as in an iterator).

      • toString

        public java.lang.String toString()
        Overrides:
        toString in class java.lang.Object
      • update

        public void update​(Timer timer,
                           TimerEvent.TimerEventType etype,
                           long time)
        Re-use the same TimerEvent instance with different data. Used to create flyweight instances for iteration over a collection of TimerEvent instances.
      • incrementTime

        public void incrementTime​(long update)
      • timer

        public Timer timer()
        The name of the Timer used to create this entry.
      • type

        public TimerEvent.TimerEventType type()
        Type of event: ENTER for start of interval for a Timer, EXIT for end of the interval.
      • time

        public long time()
        Time of event in nanoseconds since the TimerLog was created or cleared.
