Class Hours

java.lang.Object
gaiasky.util.gaia.time.ConcreteDuration
gaiasky.util.gaia.time.Hours
All Implemented Interfaces:
Duration, java.io.Serializable

public class Hours
extends ConcreteDuration
implements java.io.Serializable
A finite number of hours 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.
