Re: [udig-devel] Get features

[Jesse Eichar <jeichar@xxxxxxxxxxxxxxx>]

If you are not a tool you can get a context by calling 
ApplicationGIS.createContext().  (You need udig 1.1.0).

Or you can use the following snippet if you are not using 1.1.0

FeatureCollection collection=layer.getResource(FeatureSource.class, 
null).getFeatures(
               layer.createBBoxFilter(bbox, null));
