FeatureTypeTransformer

public class FeatureTypeTransformer
extends TransformerBase

Transformer that transforms feature types into (hopefully) valid XML schemas. This class may be used by geoserver in the future to automatically create XML schemas for the DescribeFeatureType request.

   FeatureType type = ...; // you have it from somewhere
   FeatureTypeTransformer t = new FeatureTypeTransformer();
   t.transform(type, System.out);
 

The following table lists the mapping between java types and xml schema data types for attribute types.

TODO:

TODO: Support GeometryCollection., REVISIT: Should support a bit more for the header, like being able to set the schemaLocation. It also should declare and import the gml namespace - it's always used as all extend gml:AbstractFeatureType. Also should be able to set the global substitution group, so that this type can be used directly as a feature.
