[jira] [Commented] (AVRO-814) SpecificDatumReader.newRecord always looks up the classname

["Doug Cutting (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/AVRO-814?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13027912#comment-13027912 ] 

Doug Cutting commented on AVRO-814:
-----------------------------------

I'm not exactly sure what you want to happen.  Do you want a SpecificDatumReader(Class) to retain a pointer to the class and use that in newRecord()?  If so, that will only work for the class of the top-level instance, nested classes would still use the class named in the schema.

> Even when given an instance of the record class, SpecificDatumReader looks up the Class in the SpecificData Class cache. This breaks decoding into subclasses of a generated record class without programmatically modifying the schema of the subclass, and is probably unnecessary.
