Package gaiasky.util.gaia.time

Class NanoSecs

java.lang.Object

gaiasky.util.gaia.time.ConcreteDuration

gaiasky.util.gaia.time.NanoSecs

All Implemented Interfaces:

Duration, Serializable

public class NanoSecs
extends ConcreteDuration
implements Serializable

A finite number of nanoseconds.

There are two implementations provided of the conversions methods one as object interface, where an object of the current class has to be instantiated. The oder implementation is provided as static class methods.

Performance tests of both implementations have come up with a performance improvement of 20% of the static methods compared with the object methods.
