It seems to me what you want is a "single side buffer". JTS offers it, but it's not mapped to a filter function, some coding is needed back in Geotools. Have a look at FilterFunction_buffer in the GeoTools main module for inspiration, and see META-INF/services to see how they are registered in the plugin system.
