org.geotools.feature.type
Class ChoiceAttributeType.Geometric

java.lang.Object
  org.geotools.feature.type.ChoiceAttributeType
      org.geotools.feature.type.ChoiceAttributeType.Geometric

All Implemented Interfaces:

AttributeType, GeometryAttributeType, PrimativeAttributeType

Enclosing class:

ChoiceAttributeType

public static final class ChoiceAttributeType.Geometric

extends ChoiceAttributeType

implements GeometryAttributeType

A special class that is made so a Choice can serve as the Default Geometry in a FeatureType, by implementing GeometryAttributeType. It must be a choice between other GeometryAttributeTypes.

Author:

Chris Holmes, TOPP

Task:

TODO: Need to write code to check that all the geometry attributes are in the same crs. Right now we just blindly assume they are and return the first.

Method Detail

getCoordinateSystem

public org.opengis.referencing.crs.CoordinateReferenceSystem getCoordinateSystem()

Description copied from interface: GeometryAttributeType

Retrieve the CS_CoordinateSystem used by this GeometryAttributeType.

OUT OF DATE: The class CoordinateSystem holds a GeometryFactory that is used for creating new content. By extension this includes the SRID, PercisionModel and CoordinateSequenceFactory information.

Specified by:

getCoordinateSystem in interface GeometryAttributeType

Returns:

CS_CoordinateSystem for this GeometryAttributeType

getGeometryFactory

public com.vividsolutions.jts.geom.GeometryFactory getGeometryFactory()

Description copied from interface: GeometryAttributeType

The Geometryfactory used for creating new content.

Replace with the following code:

 Map hints = new HashMap();
 hints.put( CoordinateReferneceSystem.class, type.getCoordinateSystem() ); 
 GeometryFactory gf = FactoryFinder.getGeometryFactory( Map hints );
 
 // You can now use gf create methods
 

Specified by:

getGeometryFactory in interface GeometryAttributeType

Returns:

GeometryFactory used for new Content

isGeometry

public boolean isGeometry()

Description copied from interface: GeometryAttributeType

Must return true

Specified by:

isGeometry in interface GeometryAttributeType

Overrides:

isGeometry in class ChoiceAttributeType
