Examples of StoredFieldVisitor

org.apache.lucene.index.StoredFieldVisitor
Expert: provides a low-level means of accessing the stored field values in an index. See {@link IndexReader#document(int,StoredFieldVisitor)}. See {@link DocumentStoredFieldVisitor}, which is a StoredFieldVisitor that builds the {@link Document} containing all stored fields. This isused by {@link IndexReader#document(int)}. @lucene.experimental
