I'd like to subclass the avro-generated classes.
Is it possible to tell avro to deserialize using a custom builder that
instantiates my subclasses?
There are some hints in the source code that this might be possible, but
what I'd really like is a small, working example...
This may be what I'm looking for:
org.apache.avro.specific.SpecificData
The getClass() method perhaps can be overridden to map incoming record
class names to java classes. Not sure if this is the right way to do it
though. There's also a getClassName() which might be a better method to
override.
Any thoughts?
What we are trying to do is emulate JAXB's ObjectFactory
functionality[1], which lets you specify which subclasses of the
generated classes are used for deserialization.
