> Key: LUCENE-3735
> URL: https://issues.apache.org/jira/browse/LUCENE-3735
> Project: Lucene - Java
> Issue Type: Sub-task
> Components: core/index
> Reporter: Uwe Schindler
> Assignee: Uwe Schindler
> Fix For: 3.6, 4.0
>
>
> The PayloadProcessorProvider has a broken API, this should be fixed. The
> current patch mimics the old behaviour, but not 100%.
> The PayloadProcessorProvider API should return a PayloadProcessor based on
> the AtomicReader instance that gets merged. As AtomicReader do no longer know
> the directory they are reside (they could be e.g. FilterIndexReaders,
> MemoryIndexes,...) a selection by Directory is no longer possible.
> The current code in Lucene trunk mimics the old behavior by doing an
> instanceof SegmentReader check and then asking for a DirProvider. If
> something else is merged in, Payload processing is not supported. This should
> be changed, the old API could be kept backwards compatible by moving the
> instanceof check in a "convenience class" DirPayloadProcessorProvider,
> extending PayloadProcessorProvider.
