> Key: IMAP-11

> Issue Type: Improvement
> Reporter: Joachim Draeger

> Fix For: 0.1

> The current design is really not bad and for the most commands absolutely
> sufficient.
> But at least search and fetch are candidates to follow a more strict template.
> 1. parse the complete command and put the information into a request object
> 2. apply the request: perform changes / fetch data, return a response object
> 3. render the response
> Parts of the request/response objects could come from the backend API
> (MailboxManager)
> This should be done in three 3 classes that can be tested separately. For
> trivial commands we could allow simplification like nested classes.
> (This is only a very quick draft of things I have in mind)
> Another resource is handlerapi2, of course.
> It should integrate smoothly in the current code base, without the need to
> change all commands at once. (At first only Fetch and Search)
> Running from AbstractJamesHandler is mandatory.
> (one step after the other, keep backward compatibility)
> Ideally we could use existing solutions and follow the schema of MINA.
> We could prepare a future switch to MINA and make first experiments.
> Maybe we could make use of ANTLR for the parsing part.
