Constructor Details

InternalGeoCentroid

public InternalGeoCentroid(String name,
 GeoPoint centroid,
 long count,
 Map<String,Object> metadata)

InternalGeoCentroid

public InternalGeoCentroid(StreamInput in)
                    throws IOException

Read from a stream.

Throws:

IOException

Method Details

encodeLatLon

public static long encodeLatLon(double lat,
 double lon)

decodeLatitude

public static double decodeLatitude(long encodedLatLon)

decodeLongitude

public static double decodeLongitude(long encodedLatLon)

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

centroid

public GeoPoint centroid()

Specified by:

centroid in interface GeoCentroid

count

public long count()

Specified by:

count in interface GeoCentroid

reduce

public InternalGeoCentroid 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

mustReduceOnSingleInternalAgg

protected boolean mustReduceOnSingleInternalAgg()

Description copied from class: InternalAggregation
