All Implemented Interfaces:

Serializable

public final class DurationUnit

extends AbstractUnit

Defines a set of iterable type safe constants related to time.
In situations where the conversion between units isn't exact (eg days in month) the conversionfactor holds the maximum value. Use them just like standard int constants eg DurationUnit.HOUR
(Uses net.agmodel.resources.PhysicalResources for the unit names). Follows the style for typed classes described in "Create enumerated constants in Java" by Eric Armstrong JavaWorld July 1997
