[udig-devel] Help with simple plugin

[Pedro Da Ros]

Hey Cory,

thanks a lot for your info, this tutorial helped me a lot :).

I´m still fighting but am starting to understand a bit. I dont know,
but I´m finding uDig a little bit too complex. I just want to add a
layer to the map, and I seem to have to implement a lot of classes to
do that :( .

Does anyone know if are there some (UML?) diagrams to help me
understanding the big picture? I couldnt find any (neither on the site
nor searching on Google). Or maybe some docs on this inter-relation
between the classes/interfaces like Map, Layer, Feature, FeatureType,
etc.


Thanks,
-Pedro Da Ros
