Package org.elasticsearch.search.aggregations.bucket.geogrid

Class InternalGeoGrid<B extends InternalGeoGridBucket>

java.lang.Object

org.elasticsearch.search.aggregations.InternalAggregation

org.elasticsearch.search.aggregations.InternalMultiBucketAggregation<InternalGeoGrid,InternalGeoGridBucket>

org.elasticsearch.search.aggregations.bucket.geogrid.InternalGeoGrid<B>

All Implemented Interfaces:

NamedWriteable, Writeable, ToXContent, ToXContentFragment, Aggregation, GeoGrid, MultiBucketsAggregation

Direct Known Subclasses:

InternalGeoHashGrid, InternalGeoTileGrid

public abstract class InternalGeoGrid<B extends InternalGeoGridBucket>
extends InternalMultiBucketAggregation<InternalGeoGrid,InternalGeoGridBucket>
implements GeoGrid

Represents a grid of cells where each cell's location is determined by a specific geo hashing algorithm. All geo-grid hash-encoding in a grid are of the same precision and held internally as a single long for efficiency's sake.

Constructor Detail

InternalGeoGrid

public InternalGeoGrid(StreamInput in)
                throws java.io.IOException

Read from a stream.

Throws:

java.io.IOException

Method Detail

doWriteTo

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

Specified by:

doWriteTo in class InternalAggregation

Throws:

java.io.IOException

getBuckets

public java.util.List<InternalGeoGridBucket> getBuckets()

Specified by:

getBuckets in interface GeoGrid

Specified by:

getBuckets in interface MultiBucketsAggregation

Specified by:

getBuckets in class InternalMultiBucketAggregation<InternalGeoGrid,InternalGeoGridBucket>

Returns:

The buckets of this aggregation.

doReduce

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

Specified by:

doReduce in class InternalAggregation

doXContentBody

public XContentBuilder doXContentBody(XContentBuilder builder,
                                      ToXContent.Params params)
                               throws java.io.IOException

Specified by:

doXContentBody in class InternalAggregation

Throws:

java.io.IOException

doHashCode

protected int doHashCode()

Description copied from class: InternalAggregation

Opportunity for subclasses to the InternalAggregation.hashCode() for this class.

Specified by:

doHashCode in class InternalAggregation

doEquals

protected boolean doEquals(java.lang.Object obj)

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:

doEquals in class InternalAggregation
