Description

This method creates a selection set that contains the underlying class' invalid objects.
A query filter can be provided to validate a portion of the class' objects, but passing a null value will evaluate all of the class' objects.
The Workspace parameter indicates where the selection set is to be created. In most cases, a null value can be used, indicating that the class' workspace be used. If necessary, a scratch workspace may also be used.

Remarks

Validate on a row occurs in five steps:

  1. Validate the subtype

  2. Validate the attribute rules

  3. Validate the network connectivity rules (if network feature)

  4. Validate the relationship rules

  5. Perform custom validation (using optional class extension)

The validate process stops once a row is found invalid. For example, if a network feature violates an attribute rule, the validation process stops and the feature's network connectivity rules are not evaluated until the attribute rule violation is corrected.
