Examples of org.apache.blur.utils.ResetableDocumentStoredFieldVisitor

org.apache.blur.utils.ResetableDocumentStoredFieldVisitor
A {@link StoredFieldVisitor} that creates a {@link Document} containing allstored fields, or only specific requested fields provided to {@link #DocumentStoredFieldVisitor(Set)}.
This is used by {@link IndexReader#document(int)} to load a document. @lucene.experimental
