Constructor Details

MeasurementRange

public MeasurementRange(Class<T> type,
 T minimum,
 boolean isMinIncluded,
 T maximum,
 boolean isMaxIncluded,
 Unit<?> units)

Constructs a range of Number objects.

Parameters:

type - The element class, usually one of Byte, Short, Integer, Long, Float or Double.

minimum - The minimum value.

isMinIncluded - Defines whether the minimum value is included in the Range.

maximum - The maximum value.

isMaxIncluded - Defines whether the maximum value is included in the Range.

units - The units of measurement, or null if unknown.

MeasurementRange

public MeasurementRange(Range<T> range,
 Unit<?> units)

Constructs a range with the same values than the specified range.

Parameters:

range - The range to copy. The elements must be Number instances.

units - The units of measurement, or null if unknown.

Method Details

create

public static MeasurementRange<Float> create(float minimum,
 float maximum,
 Unit<?> units)

Constructs an inclusive range of float values.

Parameters:

minimum - The minimum value, inclusive.

maximum - The maximum value, inclusive.

units - The units of measurement, or null if unknown.

Returns:

The measurement range.

Since:

2.5

create

public static MeasurementRange<Float> create(float minimum,
 boolean isMinIncluded,
 float maximum,
 boolean isMaxIncluded,
 Unit<?> units)

Constructs a range of float values.

Parameters:

minimum - The minimum value.

isMinIncluded - Defines whether the minimum value is included in the Range.

maximum - The maximum value.

isMaxIncluded - Defines whether the maximum value is included in the Range.

units - The units of measurement, or null if unknown.

Returns:

The measurement range.

Since:

2.5

create

public static MeasurementRange<Double> create(double minimum,
 double maximum,
 Unit<?> units)

Constructs an inclusive range of double values.

Parameters:

minimum - The minimum value, inclusive.

maximum - The maximum value, inclusive.

units - The units of measurement, or null if unknown.

Returns:

The measurement range.

create

public static MeasurementRange<Double> create(double minimum,
 boolean isMinIncluded,
 double maximum,
 boolean isMaxIncluded,
 Unit<?> units)

Constructs a range of double values.

Parameters:

minimum - The minimum value.

isMinIncluded - Defines whether the minimum value is included in the Range.

maximum - The maximum value.

isMaxIncluded - Defines whether the maximum value is included in the Range.

units - The units of measurement, or null if unknown.

Returns:

The measurement range.

getUnits

public Unit<?> getUnits()

Returns the units of measurement, or null if unknown.

Returns:

The units of measurement, or null.

convertTo

public MeasurementRange convertTo(Unit<?> targetUnits)
                           throws IllegalArgumentException

Converts this range to the specified units. If this measurement range has null units, then the specified target units are simply assigned to the returned range with no other changes.

Parameters:

targetUnits - the target units.

Returns:

The converted range, or this if no conversion is needed.

Throws:

IllegalArgumentException - if the target units are not compatible with this range units.

castTo

public <N extends Number & Comparable<? super N>>
MeasurementRange<N> castTo(Class<N> type)

Casts this range to the specified type.

Overrides:

castTo in class NumberRange<T extends Number & Comparable<? super T>>

Type Parameters:

N - The class to cast to.

Parameters:

type - The class to cast to. Must be one of Byte, Short, Integer, Long, Float or Double.

Returns:
