public class IndexedDbaseFileReader extends DbaseFileReader
A DbaseFileReader is used to read a dbase III format file.
The general use of this class is: 
 FileChannel in = new FileInputStream("thefile.dbf").getChannel();
 DbaseFileReader r = new DbaseFileReader( in )
 Object[] fields = new Object[r.getHeader().getNumFields()];
 while (r.hasNext()) {
    r.readEntry(fields);
    // do stuff
 }
 r.close();
For consumers who wish to be a bit more selective with their reading of rows, the Row object has been added. The semantics are the same as using the readEntry method, but remember that the Row object is always the same. The values are parsed as they are read, so it pays to copy them out (as each call to Row.read() will result in an expensive String parse).
EACH CALL TO readEntry OR readRow ADVANCES THE FILE!
An example of using the Row method of reading: 
 FileChannel in = new FileInputStream("thefile.dbf").getChannel();
 DbaseFileReader r = new DbaseFileReader( in )
 int fields = r.getHeader().getNumFields();
 while (r.hasNext()) {
   DbaseFileReader.Row row = r.readRow();
   for (int i = 0; i < fields; i++) {
     // do stuff
     Foo.bar( row.read(i) );
   }
 }
 r.close();
