True if Null values are rejected | |||||
The dataClassAttribute.mandatory contains True if Null value input is rejected for the attribute.
This property is not returned if dataClassAttribute.kind = "relatedEntity" or "relatedEntities".
Note: For generic programming, you can use Bool(dataClassAttribute.mandatory) to get a valid value (false) even if mandatory is not returned.
Warning: This property corresponds to the "Reject NULL value input" field property at the 4D database level. It is unrelated to the existing "Mandatory" property which is a data entry control option for a table.
