UnmappedSampler

public UnmappedSampler(StreamInput in)
                throws IOException

Read from a stream.

Throws:

IOException

Method Details

getWriteableName

public String getWriteableName()

Description copied from interface: NamedWriteable

Returns the name of the writeable object

Specified by:

getWriteableName in interface NamedWriteable

Overrides:

getWriteableName in class InternalSampler

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 InternalSingleBucketAggregation

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

Overrides:

doXContentBody in class InternalSingleBucketAggregation

Throws:

IOException
