Result of the running the significant terms aggregation on an unmapped field.

Nested Class Summary

Nested Classes

Modifier and Type	Class	Description
protected static class	UnmappedSignificantTerms.Bucket	Concrete type that can't be built because Java needs a concrete type so InternalTerms.Bucket can have a self type but UnmappedTerms doesn't ever need to build it because it never returns any buckets.

Constructor Details

UnmappedSignificantTerms

public UnmappedSignificantTerms(String name,
 int requiredSize,
 long minDocCount,
 Map<String,Object> metadata)

UnmappedSignificantTerms

public UnmappedSignificantTerms(StreamInput in)
                         throws IOException

Read from a stream.

Throws:

IOException

Method Details

writeTermTypeInfoTo

protected void writeTermTypeInfoTo(StreamOutput out)
                            throws IOException

Specified by:

writeTermTypeInfoTo in class InternalSignificantTerms<UnmappedSignificantTerms,UnmappedSignificantTerms.Bucket>

Throws:

IOException

getWriteableName

public String getWriteableName()

Description copied from interface: NamedWriteable

Returns the name of the writeable object

getType

public String getType()

Specified by:

getType in interface Aggregation

Overrides:

getType in class InternalAggregation

Returns:

a string representing the type of the aggregation. This type is added to the aggregation name in the response, so that it can later be used by clients to determine type of the aggregation and parse it into the proper object.

create

public UnmappedSignificantTerms create(List<UnmappedSignificantTerms.Bucket> buckets)

Description copied from class: InternalMultiBucketAggregation

Create a new copy of this Aggregation with the same settings as this Aggregation and contains the provided buckets.

Specified by:

create in class InternalMultiBucketAggregation<UnmappedSignificantTerms,UnmappedSignificantTerms.Bucket>

Parameters:

buckets - the buckets to use in the new Aggregation

Returns:

the new Aggregation

createBucket

public UnmappedSignificantTerms.Bucket createBucket(InternalAggregations aggregations,
 UnmappedSignificantTerms.Bucket prototype)

Description copied from class: InternalMultiBucketAggregation

Create a new InternalMultiBucketAggregation.InternalBucket using the provided prototype bucket and aggregations.

Specified by:

createBucket in class InternalMultiBucketAggregation<UnmappedSignificantTerms,UnmappedSignificantTerms.Bucket>

Parameters:

aggregations - the aggregations for the new bucket

prototype - the bucket to use as a prototype

Returns:

the new bucket

create

protected UnmappedSignificantTerms create(long subsetSize,
 long supersetSize,
 List<UnmappedSignificantTerms.Bucket> buckets)

Specified by:

create in class InternalSignificantTerms<UnmappedSignificantTerms,UnmappedSignificantTerms.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.

Overrides:

reduce in class InternalSignificantTerms<UnmappedSignificantTerms,UnmappedSignificantTerms.Bucket>

See Also:

InternalAggregation.mustReduceOnSingleInternalAgg()

isMapped

public boolean isMapped()

Description copied from class: InternalAggregation

Return true if this aggregation is mapped, and can lead a reduction. If this agg returns false, it should return itself if asked to lead a reduction

Overrides:

isMapped in class InternalAggregation

doXContentBody

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

Specified by:

doXContentBody in class InternalAggregation

Throws:

IOException

createBucketsArray

protected UnmappedSignificantTerms.Bucket[] createBucketsArray(int size)

Description copied from class: InternalSignificantTerms

Create an array to hold some buckets. Used in collecting the results.

Specified by:

Returns:

The buckets of this aggregation.

getBucketByKey

public SignificantTerms.Bucket getBucketByKey(String term)

Description copied from interface: SignificantTerms

Get the bucket for the given term, or null if there is no such bucket.

getSignificanceHeuristic

protected SignificanceHeuristic getSignificanceHeuristic()
