Interface Duration

All Superinterfaces:
Serializable
All Known Implementing Classes:
ConcreteDuration, Days, Hours, JulianYears, Mins, NanoSecs, Revs, Secs
public interface Duration extends Serializable
A Duration represents an amount of time on a proper time scale. 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.
