Examples of org.apache.lucene.index.PayloadProcessorProvider

org.apache.lucene.index.PayloadProcessorProvider
Provides a {@link ReaderPayloadProcessor} to be used for a {@link Directory}. This allows using different {@link ReaderPayloadProcessor}s for different source {@link IndexReader}, for e.g. to perform different processing of payloads of different directories.
NOTE: to avoid processing payloads of certain directories, you can return null in {@link #getReaderProcessor}.
NOTE: it is possible that the same {@link ReaderPayloadProcessor} will berequested for the same {@link Directory} concurrently. Therefore, to avoidconcurrency issues you should return different instances for different threads. Usually, if your {@link ReaderPayloadProcessor} does not maintain statethis is not a problem. The merge code ensures that the {@link ReaderPayloadProcessor} instance you return will be accessed by onethread to obtain the {@link PayloadProcessor}s for different terms. @lucene.experimental
