This is what I would do ::

   ILayer selectedLayer = handler.getContext().getSelectedLayer() ;
   FeatureCollection collection = null ;
   FeatureStore store = selectedLayer.getResource(
      FeatureStore.class, new SubProgressMonitor(monitor, 1)) ;
   collection = store.getFeatures(selectedLayer.getFilter()) ;
   FeatureIterator reader = collection.features() ;
   if (reader.hasNext()) {
      // process selected features
   }

where handler is a ToolHandler, but you can get the selected layer from the
active map as well ::

   ApplicationGIS.getActiveMap().getEditManager().getSelectedLayer() ;
