commit 4ce5a2bb8ab487176642dd0ebfd5ef1d960bc5ea
Author: Karsten Loesing <karsten.loesing(a)gmx.net>
Date: Thu Jun 20 18:06:42 2013 +0200
Refactor more parts in preparation for moving to a database.
- Introduce a new document type hierarchy for internal text-based status
documents (*Status) and JSON-formatted output documents (*Document).
Prepares moving all formatting and parsing code to DocumentStore or
Document subtypes, so that *Writer classes won't have to worry about
document formats anymore.
- Rename Node to NodeStatus and make it handle its own formatting and
parsing. DocumentStore now returns NodeStatus objects instead of one
large summary status documents containing all nodes. Prepares moving to
a database design where each NodeStatus object will have its own
database entry. DocumentStore still reads and writes a single summary
status document, so that file formats don't change, but keeps a local
NodeStatus cache in memory and writes this file to disk before exiting.
- Don't share CurrentNodes code between back-end and front-end. Move
back-end-only functionality to new NodeDataWriter and front-end-only
functionality to ResourceServlet.
- Rename DetailDataWriter to DetailsDataWriter for consistency with other
document types.
