  • Constructor Details

    • Units

      protected Units(SystemOfUnits system)
      Creates a new factory which will use the given system of units.
      Parameters:
      system - the system of units to use for creating base units.

  • Method Details

    • getDefault

      public static Units getDefault()
      Returns the default units factory. This factory uses the unit service provider which is current at the time of the first invocation of this method.
      Returns:
      the default units factory.
