TibrvTimer()

Constructor

Declaration

TibrvTimer(
    TibrvQueue           queue,
    TibrvTimerCallback   callback,
    double               interval,
    java.lang.Object     closure)
  throws TibrvException

Purpose

Start a timer.

Remarks

All timers are repeating timers. To simulate a once-only timer, code the callback method to destroy the timer.

Parameter	Description
queue	At each time interval, place the event on this event queue.
callback	On dispatch, process the event with this interface implementation.
interval	The timer triggers its callback method at this repeating interval (in seconds).
closure	Store this closure data in the event object.

Timer Granularity

Express the timer interval (in seconds) as a double (64-bit floating point number). This representation allows microsecond granularity for intervals for over 100 years. The actual granularity of intervals depends on Java implementation constraints, as well as hardware and operating system constraints.

The JNI implementation supports fine-resolution timers through the underlying C layer. Most releases of the JVM limit the Java implementation to 10 millisecond resolution.
