public class DDR

extends Record

The ISO 8211 data definition record. The DDR (as I understand it) describes the format of the remaining records in the file. It's been pointed out to me by someone who knows what he's doing that since S57 is a single format implemented in ISO8211 I don't actually need to parse the DDR because every S57 file should have the same DDR. Well, I didn't know that when I started; and, more to the point, if I don't parse the DDR I have to write special purpose code to interpret each of the S57 record types, whereas if I get this right the same generic parser, using the DDR data, should parse all.
