Sure. You generate the JCas classes once and then you add the methods you want to them. Cf. e.g.
https://github.com/dkpro/dkpro-core/blob/8043e10bf10a61fe47e21946ea609bda9f2278a0/dkpro-core-api-metadata-asl/src/main/java/de/tudarmstadt/ukp/dkpro/core/api/metadata/type/DocumentMetaData.java#L290-L447 But the question is: why do you want to add new methods? (and is it really a good idea?) Cheers, -- Richard
