Re: [udig-devel] Layers Type - Polygon or Multiploygon

[Jody Garnett <jgarnett@xxxxxxxxxxxxxxx>]

You can ask a Layer for its FeatureType and from there get the 
GeometryAttributeType which will indicate which class is being used. We 
have some code around that looks at this stuff in order to decide what 
default Style to apply when the layer is created and what little Glyph 
to draw in the legend view.

You may need to make this decision based on the Layer's default 
GeoResource (since it is the keeper of the FeatureType). So chances are 
this is all reduced to a utility method if you look in the codebase.

Cheers,
Jody
