Class IndexedShapefileDataStore.Reader

java.lang.Object
  org.geotools.data.AbstractAttributeIO
      org.geotools.data.shapefile.indexed.IndexedShapefileDataStore.Reader

All Implemented Interfaces:

AttributeReader

Enclosing class:

IndexedShapefileDataStore

protected static class IndexedShapefileDataStore.Reader

extends AbstractAttributeIO

implements AttributeReader

An AttributeReader implementation for shape. 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

Constructor Detail

IndexedShapefileDataStore.Reader

public IndexedShapefileDataStore.Reader(AttributeType[] atts,
                                        ShapefileReader shp,
                                        IndexedDbaseFileReader dbf,
                                        java.util.List goodRecs)

Create the shape reader

Parameters:

atts - - the attributes that we are going to read.

shp - - the shape reader, required
