getField, setField in org.apache.gora.avro.PersistentDatumReader

Hi,
I'm busy reading through your excellent code, compiling various snippets to understand how things work and I'm having problems in trying to compile PersistentDatumReader - it's unable to find getField(record, name, pos) and setField(record, name, pos, ....) in Object readRecord(Object old, Schema expected, ResolvingDecoder in);
I have a feeling that I've missed an installation step somewhere. Could anyone give me a pointer on what I should have done to get this to compile.
Thanks,Nick.

That sure is a rocky road right enough.
We're in the process of making the Avro upgrade to 1.7.x in Gora and it is
not trivial, although we were given a huge pointer by Ed a while back.
I wonder if you've been able to grab/or even seen the Avro patches I put up
on our Jira last week? They will undoubtedly help you a long way of doing
the Avro upgrade... unfortunately your on your own with the C++ stuff ;)
Thanks

been moved to GenericData; so prepending getFields/setFields with getData()
works - just needs to be tested.

Hi Guys,
Sincere apologies over this, I have egg on my face as I didn't dig deep enough.
I'm trying to merge the latest avro branch with gora with a view to pruning anything which is redundant and then converting to C++ for use in an embedded device. It's a hard and rocky road. Thanks for pointing out SpecificDatumReader. In, I think, Avro 1.6.0, getFields, setFields have been moved to GenericData; so prepending getFields/setFields with getData() works - just needs to be tested.
Thanks again for the time you spent dealing with this.
CheersNick

Hi Nick,
As you've maybe noticed, getField(record, name, pos) is inherited from Avro's SpecificDatumReader [0].

If there is an error compiling, I can only imagine it is because Avro is not available at compile time?

Thanks for the info Nick. The release src should work too =(

I will try the release distribution later to verify.


Thanks,

Henry

Hi, no, I pulled pieces out of the latest src release, and checked that the code was the same in the trunk. I'll compile using maven tomorrow when I get in to work.
Thanks for getting back.
Nick.

Hi,

Just curious were you using Maven to compile the source? And also did you
try to do it against trunk.

Thanks for your patience
