  • Method Details

    • instantiateCached

      public static <U extends org.djunits.unit.Unit<U>,​ S extends org.djunits.value.vdouble.scalar.base.AbstractDoubleScalar<U,​ S>> S instantiateCached​(double value, U unit)
      Instantiate the DoubleScalar based on its unit. Rigid check on types for the compiler.
      Type Parameters:
      U - the unit
      S - the return type
      Parameters:
      value - double; the value
      unit - U; the unit in which the value is expressed
      Returns:
      an instantiated DoubleScalar with the value expressed in the unit

    • instantiateAnonymousCached

      public static <S extends org.djunits.value.vdouble.scalar.base.AbstractDoubleScalar<?,​ S>> S instantiateAnonymousCached​(double value, org.djunits.unit.Unit<?> unit)
      Instantiate the DoubleScalar based on its unit. Loose check for types on the compiler. This allows the unit to be specified as a Unit<?> type.
      Note that it is possible to make mistakes with anonymous units.
      Type Parameters:
      S - the return type
      Parameters:
      value - double; the value
      unit - Unit<?>; the unit in which the value is expressed
      Returns:
      an instantiated DoubleScalar with the value expressed in the unit

    • instantiateCascade

      public static <U extends org.djunits.unit.Unit<U>,​ S extends org.djunits.value.vdouble.scalar.base.AbstractDoubleScalar<U,​ S>> S instantiateCascade​(double value, U unit)
      Instantiate the DoubleScalar based on its unit. Rigid check on types for the compiler.
      Type Parameters:
      U - the unit
      S - the return type
      Parameters:
      value - double; the value
      unit - U; the unit in which the value is expressed
      Returns:
      an instantiated DoubleScalar with the value expressed in the unit

    • instantiateAnonymousCascade

      public static <S extends org.djunits.value.vdouble.scalar.base.AbstractDoubleScalar<?,​ S>> S instantiateAnonymousCascade​(double value, org.djunits.unit.Unit<?> unit)
      Instantiate the DoubleScalar based on its unit. Loose check for types on the compiler. This allows the unit to be specified as a Unit<?> type.
      Note that it is possible to make mistakes with anonymous units.
      Type Parameters:
      S - the return type
      Parameters:
      value - double; the value
      unit - Unit<?>; the unit in which the value is expressed
      Returns:
      an instantiated DoubleScalar with the value expressed in the unit

    • instantiateNonCached
