Hi Michael, hi everyone, Here is how to use the NumberFormatFunction.
1) First, you have to register it so the factory can find it dynamically.
To do so, you have to create a META-INF/services folder in your jar file and put in it a simple text file called "org.opengis.filter.expression". You have to use this file name because the NumberFormatFunction implements that interface and this is the way for the factory to find it (I guess).
In the file, there is just one line of text indicating where the function is : org.my.package.NumberFormatFunction. Do not forget that the META-INF/services directory should be in the classpath when you run your application, otherwise, it will fail loading the function.
2) Then, you have to create your style (sample code attached to this mail). I only tryed it programmatically, I did'nt test it in a SLD.
sample.java

Hi Ben, Many thanks for posting your code. I've just been studying it. If it's not too much trouble could you post a little snippet sometime showing how you would use this programmatically please ? No hurry. cheers Michael
