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, org.elasticsearch.common.xcontent.ToXContent, org.elasticsearch.common.xcontent.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 Details

InternalGeoGrid

public InternalGeoGrid(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

getBuckets

public 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.

reduce

public InternalGeoGrid 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

See Also:

InternalAggregation.mustReduceOnSingleInternalAgg()

reduceBucket

protected InternalGeoGridBucket reduceBucket(List<InternalGeoGridBucket> buckets,
 InternalAggregation.ReduceContext context)

Description copied from class: InternalMultiBucketAggregation

Reduce a list of same-keyed buckets (from multiple shards) to a single bucket. This requires all buckets to have the same key.

Specified by:

reduceBucket in class InternalMultiBucketAggregation<InternalGeoGrid,InternalGeoGridBucket>

doXContentBody

public org.elasticsearch.common.xcontent.XContentBuilder doXContentBody(org.elasticsearch.common.xcontent.XContentBuilder builder,
 org.elasticsearch.common.xcontent.ToXContent.Params params)

Specified by:

doXContentBody in class InternalAggregation

Throws:

IOException

hashCode

public int hashCode()

Overrides:

hashCode in class InternalAggregation

equals

public boolean equals(Object obj)

Overrides:

equals in class InternalAggregation
