[Simple-support] value preprocessing before deserialization

[Paweł K. <paw...@gm...>]

Hi,

I need to (de)serialize a list of java beans to/from XML message. The
problem is that all values (i.e. integers, doubles, dates etc.) in
each bean are sent as base64-encoded strings, e.g.:

<response>
    <person>
        <name>[base64-encoded String]</name>
        <age>[base64-encoded int]</name>
        <birthDate>[base64-encoded date]</birthDate>
        ...
    </person>
</response>

Is there a simple way to decode those beans without holding all their
fields as Strings?

I thought of creating a custom transformation, but then I would have
to reimplement all the default transforms as they are not exported by
the org.simpleframework.xml  package (all classes have "package
private" scope).
I was also considering a custom strategy, but again - the
DefaultStrategy is "package private" too.

Thanks in advance,

Pawel
