I'm assuming for now that you are using a specific writer and you have a union
schema with two records FOO and BAR (you should get two classes FOO and BAR
generated by avro tools):
FOO fooObj = ....
BAR barObj = ....
BAR barObj2 = ....
ByteArrayOutputStream out = new ByteArrayOutputStream();
DatumWriter<GenericRecord> writer = new
SpecificDatumWriter<Record>(yourSchema);
encoder = EncoderFactory.get().binaryEncoder(out, encoder);
writer.write(fooObj, encoder);
writer.write(barObj, encoder);
writer.write(barObj2, encoder);
encoder.flush();
out.close();
Does it make sense?
