[jira] Created: (MIME4J-147) Move "default parsing" logic from AbstractField to DefaultFieldParser

Move "default parsing" logic from AbstractField to DefaultFieldParser
---------------------------------------------------------------------

                 Key: MIME4J-147
                 URL: https://issues.apache.org/jira/browse/MIME4J-147
             Project: JAMES Mime4j
          Issue Type: Improvement
    Affects Versions: 0.6
            Reporter: Stefano Bagnara
            Assignee: Stefano Bagnara
            Priority: Critical
             Fix For: 0.7


As suggested in the ml we should move the default "delegation based" parsing logic from AbstractField to DefaultFieldParser.
This way we remove a lot of cycles in the code and the "default parsing" is exposed vua DefaultFieldParser instead of AbstractField (i never liked exposing a public feature via a static method of an abstract class).

here the ml message:
--
AbstractField is the abstract class extended by each specific field
implementation.

AbstractField, at the same time, provide "static" access to a
DefaultFieldParser and provides static methods to get a
DefaultFieldParser and to parse a string into a field using that
default field parser.

So every field extend abstractField but AbstractField have a link to
every of its implementations via DefaultFieldParser =>
DelegatingFieldParser.

This smells like a very bad idea. Is it me?

So, if you agree this should be improved here are 2 alternative solutions:
1) the easy fix would be to move all of the static stuff from
AbstractField to DefaultFieldParser. As the methods are public static
methods this would introduce a backward compatibility issue.
