--------------------------------------
GitHub user elmendavies opened a pull request:
https://github.com/apache/avro/pull/268
AVRO-2115
This patch is to allow defining unions in members when using the reflect
API (which was supposed to be supported). This is an example (note the @Union
used in a member):
```
class MyDatum {
@Union({Void.class, String.class, Long.class, Other.class,...})
Object o;
}
```
There are also a correction and some minor changes in the reflect API docs
to make it more clear to understand.

> Support @Union in members too

> Allow defining unions in members:
> {code:java}
> class MyDatum {
> @Nullable
> @Union({String.class, Long.class, Other.class,...})
> Object o;
> }
> {code}
> It can currently be implemented using @AvroSchema like this, but it is seems
> in my oppinion more verbose and more difficult to maintain:
> {code:java}
> @AvroSchema("[\"null\",\"string\",...")
> {code}
