extends DBFBase

DBFReader class can creates objects to represent DBF data. This Class is used to read data from a DBF file. Meta data and records can be queried against this document.

DBFReader cannot write anythng to a DBF file. For creating DBF files use DBFWriter.

Fetching rocord is possible only in the forward direction and cannot re-wound. In such situation, a suggested approach is to reconstruct the object.

The nextRecord() method returns an array of Objects and the types of these Object are as follows:

xBase Type	Java Type
C	String
N	Integer
F	Double
L	Boolean
D	java.util.Date
