Class Units

  • All Implemented Interfaces:
    Factory
    public class Units
extends PseudoFactory
    Pre-defined constants for the units of measurement used by the conformance tests. This pseudo-factory provides separated methods for all units needed by geoapi-conformance.
    Since:
    3.0.1

    • Constructor Detail

      • Units

        public 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 Detail

      • getDefault

        public static Units getDefault()
