    • compareValues

      int compareValues(Object value1, Object value2, DataSourceField field)
      A custom comparator for this SimpleType. This method will be used by the framework when it needs to compare two values of a field for equality - for example, when considering if an edited field has changed.

      Implementations of this method should return the following:

      • 0 if the two values are equal
      • -1 if the first value is greater than the second
      • 1 if the second value is greater than the first
      Parameters:
      value1 - First value for comparison
      value2 - Second value for comparison
      field - An instance of DataClass representing the field for which we are comparing values, as extra context for the comparator.
      Returns:
      -1, 0 or 1, as described above
