@Deprecated
public class Dbf
extends java.lang.Object

This class represents a DBF (or DBase) file.

Construct it with a URL or File (including the .dbf) this causes the header and field definitions to be read.

Later queries return rows or columns of the database.

If a URL is specified then the whole file is read into memory
if a file is specified then a randomAccess system is used.
