                            throws IOException

Throws:

IOException

storedFieldLoaders

public Stream<Map.Entry<String,SourceLoader.SyntheticFieldLoader.StoredFieldLoader>> storedFieldLoaders()

Description copied from interface: SourceLoader.SyntheticFieldLoader

A Stream mapping stored field paths to a place to put them so they can be included in the next document.

Specified by:

storedFieldLoaders in interface SourceLoader.SyntheticFieldLoader

docValuesLoader

public SourceLoader.SyntheticFieldLoader.DocValuesLoader docValuesLoader(org.apache.lucene.index.LeafReader reader,
 int[] docIdsInLeaf)
                                                                  throws IOException

Description copied from interface: SourceLoader.SyntheticFieldLoader

Build something to load doc values for this field or return null if there are no doc values for this field to load.

Specified by:

docValuesLoader in interface SourceLoader.SyntheticFieldLoader

Throws:

IOException

hasValue

public boolean hasValue()

Specified by:

hasValue in interface SourceLoader.SyntheticFieldLoader

write

public void write(XContentBuilder b)
           throws IOException

Description copied from interface: SourceLoader.SyntheticFieldLoader

Specified by:

write in interface SourceLoader.SyntheticFieldLoader

Throws:

IOException

docValuesOrNull

public static org.apache.lucene.index.SortedNumericDocValues docValuesOrNull(org.apache.lucene.index.LeafReader reader,
 String fieldName)
                                                                      throws IOException

Returns a SortedNumericDocValues or null if it doesn't have any doc values. See DocValues.getSortedNumeric(org.apache.lucene.index.LeafReader, java.lang.String) which is *nearly* the same, but it returns an "empty" implementation if there aren't any doc values. We need to be able to tell if there aren't any and return our empty leaf source loader.

Throws:

IOException
