 TopDocsAndMaxScore topDocs,
 SearchHits searchHits,
 Map<String,Object> metadata)

InternalTopHits

public InternalTopHits(StreamInput in)
                throws IOException

Read from a stream.

Throws:

IOException

Method Details

doWriteTo

protected void doWriteTo(StreamOutput out)
                  throws IOException

Specified by:

doWriteTo in class InternalAggregation

Throws:

IOException

getWriteableName

public String getWriteableName()

Description copied from interface: NamedWriteable

Returns the name of the writeable object

Specified by:

getWriteableName in interface NamedWriteable

getHits

public SearchHits getHits()

Specified by:

getHits in interface TopHits

Returns:

The top matching hits for the bucket

reduce

public InternalAggregation reduce(List<InternalAggregation> aggregations,
 InternalAggregation.ReduceContext reduceContext)

Description copied from class: InternalAggregation

Reduces the given aggregations to a single one and returns it. In most cases, the assumption will be the all given aggregations are of the same type (the same type as this aggregation). For best efficiency, when implementing, try reusing an existing instance (typically the first in the given list) to save on redundant object construction.

Specified by:

reduce in class InternalAggregation

Specified by:

mustReduceOnSingleInternalAgg in class InternalAggregation

getProperty
