Object
AbstractAttributeIO
ShapefileAttributeReader
- All Implemented Interfaces:
- AttributeReader
- Direct Known Subclasses:
- IndexedShapefileAttributeReader
public class ShapefileAttributeReader
- extends AbstractAttributeIO
- implements AttributeReader
An AttributeReader implementation for Shapefile. Pretty straightforward.
The default geometry is at position 0, and all dbf columns follow.
The dbf file may not be necessary, if not, just pass null as the
DbaseFileReader
