Field Detail

SI

public static final AngleUnit SI

The SI unit for angle is radian.

RADIAN

DEGREE

public static final AngleUnit DEGREE

degree.

Constructor Detail

AngleUnit

public AngleUnit(String name,
                 String abbreviation,
                 UnitSystem unitSystem,
                 AngleUnit referenceUnit,
                 double scaleFactorToReferenceUnit)

Build a user-defined unit with a conversion factor to another unit.

Parameters:

name - the long name of the unit

abbreviation - the abbreviation of the unit

unitSystem - the unit system, e.g. SI or Imperial

referenceUnit - the unit to convert to

scaleFactorToReferenceUnit - multiply a value in this unit by the factor to convert to the given reference unit

Method Detail

getStandardUnit

public final AngleUnit getStandardUnit()

Specified by:

getStandardUnit in class Unit<AngleUnit>

Returns:

the SI standard unit for this unit, or the de facto standard unit if SI is not available

getSICoefficientsString

public final String getSICoefficientsString()

Specified by:

getSICoefficientsString in class Unit<AngleUnit>

Returns:

the SI standard coefficients for this unit, e.g., kgm/s2 or m-2s2A or m^-2.s^2.A or m^-2s^2A (not necessarily normalized)

hashCode

public int hashCode()

Overrides:

hashCode in class Unit<AngleUnit>

equals

public boolean equals(Object obj)

Overrides:

equals in class Unit<AngleUnit>

equalsIgnoreNaming

public boolean equalsIgnoreNaming(Object obj)

Test if two units are the same, except for the name and abbreviation. This means for instance that for the MassUnits METRIC_TON and MEGAGRAM (both 1000 kg) equals(...) will yield false, but equalsIgnoreNaming will yield true.

Specified by:

equalsIgnoreNaming in class Unit<AngleUnit>

Parameters:

obj - the object to compare with

Returns:

true if the two units are the same numerically, except for the naming and/or abbreviation
