All Superinterfaces:

Filter

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 ...
