  org.geotools.validation.DefaultIntegrityValidation
      org.geotools.validation.attributes.UniqueFIDValidation

All Implemented Interfaces:

IntegrityValidation, Validation

public class UniqueFIDValidation

extends DefaultIntegrityValidation

Ensure every feature has a unique Feature Id specified by uniqueID.

Please note that featureIDs are not attributes. Attributes may be checked with the UniquityValidation class.

The FeatureTypes it checks against are defined by typeNames[]. If a duplicate ID is detected, an error message returned via a Validation Result used as a visitor in the validation() method.

Example Use:

 UniqueFIDIntegrityValidation x = new UniqueFIDIntegrityValidation("uniqueFID_road", "Checks if each feature has a unique ID", new String[] {"road", "river"}, "FID");
 x.validate();
