ilog.views.maps.format.shapefile.IlvDBFWriter

public class IlvDBFWriter
extends Object

This class writes the attributes files in .dbf format.

The .dbf files contain the attributes of the map objects contained in a .shp file. The output format is dBASE III+ table file.

The basic usage of this writer is to create it, then call the writeAttribute method for all the attributes. Once all the attributes are written, the close method must be called in order to flush the data and write the file header.
