                                double lon)

decodeLatitude

public static double decodeLatitude(long encodedLatLon)

decodeLongitude

public static double decodeLongitude(long encodedLatLon)

doWriteTo

protected void doWriteTo(StreamOutput out)
                  throws java.io.IOException

Specified by:

doWriteTo in class InternalAggregation

Throws:

java.io.IOException

getWriteableName

public java.lang.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

doReduce

public InternalGeoCentroid doReduce(java.util.List<InternalAggregation> aggregations,
                                    InternalAggregation.ReduceContext reduceContext)

Specified by:

doReduce in class InternalAggregation

getProperty

public java.lang.Object getProperty(java.util.List<java.lang.String> path)

Specified by:

getProperty in class InternalAggregation

doXContentBody

public XContentBuilder doXContentBody(XContentBuilder builder,
                                      ToXContent.Params params)

doEquals

public boolean doEquals(java.lang.Object o)

Description copied from class: InternalAggregation

Opportunity for subclasses to add criteria to the InternalAggregation.equals(Object) method for this class. This method can safely cast obj to the subclass since the InternalAggregation.equals(Object) method checks that obj is the same class as this

Specified by:
