Description
| Class Summary | |
| DDR | The ISO 8211 data definition record. |
| DDRField | A field in an ISO8211 record. |
| Dictionary | The dictionary of an ISO 8211 data description record. |
| Directory | The directory of an ISO 8211 record. |
| Field | A field (not a DDR field, see separate class DDRField) in an ISO8211 record. |
| ISO8211 | various constants and primitives for manipulating ISO8211 data, all static |
| ISO8211InputStream | Lots of stuff in parsing ISO8211 depends on knowing positions and offsets within the stream, but this is generally not easy with Java streams. |
| Leader | The leader of an ISO 8211 record. |
| Parser | Command line for ISO 8211 parse. |
| Reader | A reader which can read one kind of value from the stream. |
| Record | An ISO 8211 record |
| SubField | A subfield within an ISO8211 field. |
| Value | Abstract superclass for a subfield value; real classes which implement values are in the package uk.co.weft.iso8211.values |
| Exception Summary | |
| FormatException | An exception thrown when data found violates our expectations of ISO8211 format. |
| ISO8211Exception | An abstract superclass to group all exceptions generated whilst parsing ISO8211 data. |
| LostThePlotException | An exception thrown when data found violates our expectations of ISO8211 format, and we suspect it's the parser that's wrong. |
| UnexpectedEndException | An exception thrown when we reach the end of an ISO8211 stream unexpectedly |
A package to parse ISO8211 data and return a DOM tree.
ISO8211 is a nasty, obscure, opaque, antiquated data format which was never, so far as I can see, very widespread and is now primarily used as the base encoding for S-57, the IHO's standard for encoding nautical charts. This package represents reverse engineering because (at this stage in the project) I'm too much of a cheapskate to go out and buy a copy of the ISO8211 standard. It also represents an attempt to get up and running quickly.
Consequently there's a lot that's likely to be wrong here. Where I know I've skipped something important, eveded an issue, or taken a short cut and will have to revisit it later, this is represented in the comments by the string TODO:. Where I simply don't understand what's going on this is represented in the comments by the string (?).
Finally there are bits of the ISO8211 standard which aren't used by S57. I shall probably not bother to implement these, but if anyone else wants to contribute them I'll be happy to roll them in.
