    • Constructor Detail

      • Units

        protected Units​(javax.measure.spi.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 Detail

      • 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.

      • getDimensionless

        private static javax.measure.Unit<javax.measure.quantity.Dimensionless> getDimensionless​(javax.measure.spi.SystemOfUnits system)
        Returns the dimensionless unit. This is a workaround for what seems to be a bug in the reference implementation 1.0.1 of unit API.

      • getVendor

        public Citation getVendor()
        Not yet implemented.
        Specified by:
        getVendor in interface Factory
