start

Method Detail

createPoint

public static <U extends TypedUnit<U>> IRange<IQuantity> createPoint(IQuantity start)

createWithEnd

public static <U extends TypedUnit<U>> IRange<IQuantity> createWithEnd(IQuantity start,
                                                                       IQuantity end)

createWithExtent

public static <U extends TypedUnit<U>> IRange<IQuantity> createWithExtent(IQuantity start,
                                                                          ITypedQuantity<LinearUnit> extent)

createInfinite

public static IDisplayable createInfinite(IQuantity start,
                                          IQuantity end)

Create an IRange<IQuantity> if start and end both are non-null. Otherwise, create an IDisplayable that looks like an infinite range, by treating null values as minus or plus infinity, respectively. This behavior is a consequence of the current state where IQuantity and thusly IRange<IQuantity> both need to be finite. (A possible change to this state, when all kinds of quantities support being stored as doubles, is to allow Double.NEGATIVE_INFINITY and Double.POSITIVE_INFINITY as numerical quantities. In that case, this method can be replaced with createWithEnd(IQuantity, IQuantity)).

intersection

public static IRange<IQuantity> intersection(IRange<IQuantity> a,
                                             IRange<IQuantity> b)

union

public static IRange<IQuantity> union(IRange<IQuantity> a,
                                      IRange<IQuantity> b)

getStart

public ITypedQuantity<U> getStart()

Specified by:

getStart in interface IRange<U extends TypedUnit<U>>

Returns:

the start of the range

getEnd

public abstract ITypedQuantity<U> getEnd()

Specified by:

getEnd in interface IRange<U extends TypedUnit<U>>

Returns:

the end of the range

displayUsing

public String displayUsing(String formatHint)

Description copied from interface: IDisplayable

Format this object for display purposes, preferably using the formatter hinted by formatHint. If no such formatter is defined for this type, the default formatter will be used.

Specified by:

displayUsing in interface IDisplayable

Parameters:

formatHint - the format hint

Returns:

a formatted string according to the hinted (or default) formatter
