Adrien Grand created LUCENE-5304:
------------------------------------
Summary: SingletonSortedSetDocValues should allow for getting back
the wrapped instance
Key: LUCENE-5304
URL: https://issues.apache.org/jira/browse/LUCENE-5304
Project: Lucene - Core
Issue Type: Improvement
Reporter: Adrien Grand
Assignee: Adrien Grand
Priority: Minor
This idea was mentioned by Robert on LUCENE-5300
Some codecs or FieldCache impls use SingletonSortedSetDocValues when a field
which is supposed to be multi-valued is actually single-valued. By having a
getter on this class to get back the wrapped SortedDocValues instance, we could
add more specialization (which often already exists, eg. Solr's DocValuesFacets
already have a specialized impl for SortedDocValues).
