After creation, Avro schemata are immutable. To make such modifications you can use a visitor. There already is some code available to help you along: you can find an example in the module avro-compiler, that replaces references to named schemata with the actual schema. IIRC, you're looking for the Schemas class. The interface you need to implement has the word 'visitor' in the name. Kind regards, Oscar -- Oscar Westra van Holthe - Kind <os...@westravanholthe.nl> >
