      Gets the abbreviation used for the comparison type.
      Returns:
      the short-form identifier for the comparison

    • getPropertyDefinitions

      public PropertyDefinition[] getPropertyDefinitions()
      Gets the definitions for the comparison's required properties.
      Returns:
      the property definitions. If there are no required properties, null.
