int compareValues(java.lang.Object value1,
                  java.lang.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
