org.djunits.value.vdouble.scalar.base.DoubleScalar<AU,A>
org.djunits.value.vdouble.scalar.base.DoubleScalarAbs<AU,A,RU,R>
Type Parameters:
AU - the absolute unit
A - the Absolute class for reference purposes
RU - the relative unit
R - the Relative class for reference purposes
All Implemented Interfaces:
Serializable, Cloneable, Comparable<A>, Absolute<AU,A,RU,R>, Value<AU,A>
Direct Known Subclasses:
AbsoluteTemperature, Direction, Position, Time
public abstract class DoubleScalarAbs<AU extends AbsoluteLinearUnit<AU,RU>,A extends DoubleScalarAbs<AU,A,RU,R>,RU extends Unit<RU>,R extends DoubleScalarRelWithAbs<AU,A,RU,R>> extends DoubleScalar<AU,A> implements Absolute<AU,A,RU,R>
The typed, abstract DoubleScalarAbs class that forms the basis of all DoubleScalar definitions and extensions.
Note: A relative scalar class can implement the toAbs() method if it has an absolute equivalent.
