Class FeatureTypeTransformer

java.lang.Object
  org.geotools.xml.transform.TransformerBase
      org.geotools.gml.producer.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.

Java	XML Schema
String	xs:string
Byte	xs:byte
Short	xs:short
Integer	xs:int
Long	xs:long
BigInteger	xs:integer
BigDecimal	xs:decimal
java.util.Date	xs:dateTime
java.lang.Boolean	xs:boolean

Task:

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.
