Constructor Details

FlattenedSortedSetDocValuesSyntheticFieldLoader

public FlattenedSortedSetDocValuesSyntheticFieldLoader(String name,
 String simpleName)

Build a loader for flattened fields from doc values.

Parameters:

name - the name of the field to load from doc values

simpleName - the name to give the field in the rendered _source

Method Details

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

Overrides:

docValuesLoader in class SortedSetDocValuesSyntheticFieldLoader

docIdsInLeaf - can be null.

Throws:

IOException

hasValue

public boolean hasValue()

Description copied from interface: SourceLoader.SyntheticFieldLoader

Has this field loaded any values for this document?

Specified by:

hasValue in interface SourceLoader.SyntheticFieldLoader

Overrides:

hasValue in class SortedSetDocValuesSyntheticFieldLoader

write

public void write(XContentBuilder b)
           throws IOException

Description copied from interface: SourceLoader.SyntheticFieldLoader

Write values for this document.

Specified by:

write in interface SourceLoader.SyntheticFieldLoader

Overrides:

Throws:

convert

protected org.apache.lucene.util.BytesRef convert(org.apache.lucene.util.BytesRef value)

Description copied from class: SortedSetDocValuesSyntheticFieldLoader

Convert a BytesRef read from the source into bytes to write to the xcontent. This shouldn't make a deep copy if the conversion process itself doesn't require one.

Specified by:

convert in class SortedSetDocValuesSyntheticFieldLoader

preserve

protected org.apache.lucene.util.BytesRef preserve(org.apache.lucene.util.BytesRef value)

Description copied from class: SortedSetDocValuesSyntheticFieldLoader

Preserves bytes returned by SortedSetDocValuesSyntheticFieldLoader.convert(org.apache.lucene.util.BytesRef) to by written later. This should make a deep copy if SortedSetDocValuesSyntheticFieldLoader.convert(org.apache.lucene.util.BytesRef) didn't.

Specified by:

preserve in class SortedSetDocValuesSyntheticFieldLoader
