RE: [udig-devel] adding a feature to the current map

[Adrian Custer <acuster@xxxxxxxxx>]

Hello,

Yes, your type of buffer is exactly what I'm trying to do. 

While I would love, eventually, to talk about the details/robustness of
the design, for now I simply want to get *any* result.

I grab a point layer, extract the features, use their geometries to
buffer and union (JTS operations) then build a feature. Now I need to
make this feature into a "layer". I gather once I have a "layer" I can
create an AddLayerCommand and use IMap.sendCommand(A)Sync() to add the
layer to the map. 

How do we go from having a Geotools Feature to having a uDig Layer? 

thanks,
adrian
