Class ShapefileDataStore.Reader

java.lang.Object
  org.geotools.data.AbstractAttributeIO
      org.geotools.data.shapefile.ShapefileDataStore.Reader

All Implemented Interfaces:

AttributeReader

Enclosing class:

ShapefileDataStore

protected static class ShapefileDataStore.Reader

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

Field Summary

protected DbaseFileReader	dbf
protected ShapefileReader.Record	record
protected DbaseFileReader.Row	row
protected ShapefileReader	shp

Constructor Detail

ShapefileDataStore.Reader

public ShapefileDataStore.Reader(AttributeType[] atts,
                                 ShapefileReader shp,
                                 DbaseFileReader dbf)

Create the shapefile reader

Parameters:

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

shp - - the shapefile reader, required

dbf - - the dbf file reader. May be null, in this case no attributes will be read from the dbf file
