class Transform extends Symbolizer
A Symbolizer that wraps a geoscript.filter.Function generally used for transforming Geometry or String or Date formatting.
You can create a Transform from a CQL statement:
Transform transform = new Transform("centroid(the_geom)")
Or from a geoscript.filter.Function:
Transform transform1 = new Transform(new Function("myCentroid", {g -> g.centroid}))
