I am writing an extension and I want to use an input Port and an output Port to deliver and get boolean data.
However, when I tried to use Boolean Nodeyes=yesInput.getData(Boolean.class); , I got an error saying it should be Class <T> instead of Class <Boolean>.
I saw you posting multiple questions around creating your own extensions. Unfortunately, I don't know the answers myself, but wanted to make sure you are aware of the documentation that can be found here: For Developers - RapidMiner Documentation
Have a nice weekend
