Subject [jira] Updated: (AVRO-104) Reflective API can't handle nulls

Eelco Hillenius updated AVRO-104:

    Attachment: AVRO-104.patch

Uploaded patch with alternative solution. Works through a delegate 'ReflectSchemaDelegate'
you can set on ReflectData staticaly.

Imho, It would be more elegant to get rid of a lot of the use of static throughout the AVRO
API, but that would mean quite a few breaks, and would make using AVRO also more verbose.
This patch imho is a reasonable hack; not as ugly as setting schemas for fields directly,
and more flexible.

People like me who want to allow null values of fields in objects they let AVRO write out,
can do this:


and AVRO will create a union for every field it comes across with introspection. Clients can
also provide a custom strategy if they wish to do so.
