docsWithValue
public DocValueBits docsWithValue(org.apache.lucene.index.LeafReaderContext context) throws IOException Description copied from class:ValuesSource
Get a "has any values" view into the values. It'll try to pick the "most native" way to check if there are any values, but it builds its own view into the values so if you need any of the actual values its best to use something likeValuesSource.bytesValues(org.apache.lucene.index.LeafReaderContext)
orValuesSource.Numeric.doubleValues(org.apache.lucene.index.LeafReaderContext)
but if you just need to know if there are any values then use this.- Specified by:

- Throws:
IOException

roundingPreparer
