public interface Id extends Filter
A filter that passes only the Identifiers listed.

This application of this filter for Features is well established:

  • FeatureId - used for GML2 Features
  • GeometryId - used for GML3 Features and Geometry constructs
We also have the following identifiers:
  • RecordId - from CSW-2
  • ObjectId - from CSW-2

You can check what kind of Identifiers are supported using: 


 idCapabilities.hasFID() == true; // for FeatureId
 idCapabilities.hasEID() == true; // no idea ...
