[mapguide-users] MgByteReader and XmlSerializer question

[Maksim Sestic]

Hi Kenneth,

You're right, still it would be such a pain to maintain custom .NET wrapper
:-) What I've done in past few days is, I created a small .NET library
exposing ready-made collections of resources, e.g. Maps, Layers, etc. in
their "native" form (MgMapCollection, etc). XML parsing is used sparely,
only for global resources enumeration (to certain level). There's an
abstract class relying on singleton structure to share certain data -
UserInformation, Connection, Session... to other classes inheriting it.
Works for now.

What I had to do was to separate, so to speak, external developers and MGE
API. So they don't have direct access to, say, features - but still can
perform certain oprations over them. On the other hand, they don't rely on
resource library structure since it changes frequently. Basic access
restrictions are still implied through MG.

Regards,
Maksim Sestic
