Summary: Allow StoredFieldVisitor instances to be stateful Key: LUCENE-5158 URL: https://issues.apache.org/jira/browse/LUCENE-5158 Project: Lucene - Core Issue Type: Improvement Components: core/index Affects Versions: 4.4 Reporter: Brendan Humphreys Priority: Minor Currently there is no way to build stateful {{StoredFieldVisitor}}s. h3. Motivation We would like to optimise our access to stored fields in our indexes by utilising the {{StoredFieldVisitor.Status.STOP}} feature to stop processing fields in a document. Unfortunately we have very large indexes, and rebuilding them to have the required field order is not an option. A stateful {{StoredFieldVisitor}} could solve this; it could track which fields have been loaded for a document, and then {{STOP}} when the fields required have been loaded, regardless of the order they were loaded. h3. Implementation I've added a no-op {{public void reset()}} method to the {{StoredFieldVisitor}} base class, which gives a {{StoredFieldVisitor}} subclass an opportunity to reset its state before the fields of the next document are processed. I've added a call to {{reset()}} in all places the {{StoredFieldVisitor}} was being used. -- This message is automatically generated by JIRA.
