Interface GeometryDescriptor

All Superinterfaces:

AttributeDescriptor, PropertyDescriptor

All Known Subinterfaces:

ChoiceGeometryType

All Known Implementing Classes:

ChoiceGeometryTypeImpl, GeometryDescriptorImpl

public interface GeometryDescriptor
extends AttributeDescriptor

Describes an instance of a geometry attribute.

This interface adds no additional methods, the point of it is convenience to type narrow getType() to GeometryType.

Method Detail

getType

GeometryType getType()

Override of AttributeDescriptor.getType() which type narrows to GeometryType.

PropertyDescriptor.getType()

getCoordinateReferenceSystem

CoordinateReferenceSystem getCoordinateReferenceSystem()

The coordinate reference system in which these geometries are defined.

This method may return null, but this should only occur in cases where the actual crs is not known. A common case is when a shapefile does not have an accompanied .prj file.
