Re: [Geotools-devel] Textual Features

[David Z. <dz...@re...>]

Hi John,

My first inclination is to make a sub-class of GeometryAttributeType in
VPF, and then you can look for this GeometryAttributeType in your
renderer. This would allow VPF to continue to produce both geometrys and
textGeometrys. I'm going to point you to the
org.geotools.feature.AttributeType and
org.geotools.feature.GeometryAttributeType. 

Hope this helps you get started,

David
