Class Temperature.Unit

java.lang.Object
org.djunits.unit.AbstractUnit<TemperatureDifference>
org.djunits.quantity.Temperature.Unit
All Implemented Interfaces:
UnitInterface<TemperatureDifference>
Enclosing class:
Temperature
public static class Temperature.Unit extends AbstractUnit<TemperatureDifference>
Temperature.Unit encodes the units of relative and absolute temperature. Note that he reference is not initialized immediately for the units, since Reference needs working units to initialize itself. Therefore, references will be allocated when an reference is retrieved for the first time.

  • Field Details

  • Constructor Details

    • Unit

      public Unit(String id, String name, double scaleFactorToBaseUnit, UnitSystem unitSystem)
      Create a new Temperature unit.
      Parameters:
      id - the id or main abbreviation of the unit
      name - the full name of the unit
      scaleFactorToBaseUnit - the scale factor of the unit to convert it TO the base (SI) unit
      unitSystem - the unit system such as SI or IMPERIAL

    • Unit

      public Unit(String textualAbbreviation, String displayAbbreviation, String name, Scale scale, UnitSystem unitSystem, SIPrefix siPrefix)
      Return a derived unit for this unit, with textual abbreviation(s) and a display abbreviation.
      Parameters:
      textualAbbreviation - the textual abbreviation of the unit, which doubles as the id
      displayAbbreviation - the display abbreviation of the unit
      name - the full name of the unit
      scale - the scale to use to convert from this unit to the standard (e.g., SI, BASE) unit
      unitSystem - unit system, e.g. SI or Imperial
      siPrefix - the SI Prefix of this unit

  • Method Details

    • getReference

      protected Temperature.Reference getReference()
      Return the default reference for this unit. References are assigned lazily and safely (once) to avoid circular class initialization issues.
      Returns:
      the reference for an absolute temperature

    • siUnit

      public SIUnit siUnit()
      Description copied from interface: UnitInterface
      Return the SI unit for this unit.
      Returns:
      the SI unit for this unit

    • getBaseUnit

      public Temperature.Unit getBaseUnit()
      Description copied from interface: UnitInterface
      Return the base unit for this unit.
      Returns:
      the base unit for this unit

    • ofSi

      public TemperatureDifference ofSi(double si, UnitInterface<TemperatureDifference> displayUnit)
      Description copied from interface: UnitInterface
      Return a quantity for this unit with the SI-value and the provided display unit.
      Parameters:
      si - the value in SI or BASE units
      displayUnit - the display unit to use
      Returns:
      a quantity for this unit with the SI-value and the provided display unit

    • deriveUnit

      public Temperature.Unit deriveUnit(String abbreviation, String name, double scaleFactor, UnitSystem unitSystem)
      Description copied from class: AbstractUnit
      Return a linearly scaled derived unit for this unit, with an abbreviation and scale factor.
      Overrides:
      deriveUnit in class AbstractUnit<TemperatureDifference>
      Parameters:
      abbreviation - the textual abbreviation of the unit, which doubles as the id
      name - the full name of the unit
      scaleFactor - the (linear) scale factor to multiply with the current (linear) scale factor
      unitSystem - unit system, e.g. SI or Imperial
      Returns:
      a derived unit for this unit

    • deriveUnit

      public Temperature.Unit deriveUnit(String textualAbbreviation, String displayAbbreviation, String name, double scaleFactor, UnitSystem unitSystem, SIPrefix siPrefix)
      Description copied from class: AbstractUnit
      Return a linearly scaled derived unit for this unit, with textual abbreviation(s) and a display abbreviation.
      Specified by:
      deriveUnit in class AbstractUnit<TemperatureDifference>
      Parameters:
      textualAbbreviation - the textual abbreviation of the unit, which doubles as the id
      displayAbbreviation - the display abbreviation of the unit
      name - the full name of the unit
      scaleFactor - the (linear) scale factor to multiply with the current (linear) scale factor
      unitSystem - unit system, e.g. SI or Imperial
      siPrefix - the SI prefix of this unit
      Returns:
      a derived unit for this unit
