Perhaps we are talking different; it is not that I am withholding code from you
- it is that the request to add multiple resources does not make sense.
Question:
a) Do you want to add multiple points to an existing layer representing a shape
file? If so please ask the layer for a FeatureStore and call the addFeatures
method
-or-
b) do you want to change a layer showing points from a shape file; over to
showing points from a database table? If so you will need to change what
GeoResource the layer is using.
Layer.void setGeoResource( IGeoResource value ) is the method; because it is a
read/write method you will need to call it from a command.
final IGeoResource changeResource = ….
final ILayer layer = ….
layer.getMap().sendCommandAsync( new AbstractCommand(){
public String getName(){ return "Change Resource"; }
public void run(IProgressMonitor monitor){
((Layer)layer).setGeoResource( changeResource );
layer.refresh(null); // trigger redraw
}
});
