Constructor Details

InternalTimeSeries

public InternalTimeSeries(String name,
 List<InternalTimeSeries.InternalBucket> buckets,
 boolean keyed,
 Map<String,Object> metadata)

InternalTimeSeries

public InternalTimeSeries(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

doXContentBody

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

Specified by:

doXContentBody in class InternalAggregation

Throws:

IOException

doWriteTo

protected void doWriteTo(StreamOutput out)
                  throws IOException

Specified by:

doWriteTo in class InternalAggregation

Throws:

IOException

reduce

public InternalAggregation reduce(List<InternalAggregation> aggregations,
 AggregationReduceContext 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

• InternalAggregation.mustReduceOnSingleInternalAgg()

create

public InternalTimeSeries create(List<InternalTimeSeries.InternalBucket> 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<InternalTimeSeries,InternalTimeSeries.InternalBucket>

Parameters:

buckets - the buckets to use in the new Aggregation

Returns:

the new Aggregation

createBucket

public InternalTimeSeries.InternalBucket createBucket(InternalAggregations aggregations,
 InternalTimeSeries.InternalBucket prototype)

Description copied from class: InternalMultiBucketAggregation

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

Specified by:

createBucket in class InternalMultiBucketAggregation<InternalTimeSeries,InternalTimeSeries.InternalBucket>

Parameters:

aggregations - the aggregations for the new bucket

prototype - the bucket to use as a prototype

Returns:

the new bucket

reduceBucket

protected InternalTimeSeries.InternalBucket reduceBucket(List<InternalTimeSeries.InternalBucket> buckets,
 AggregationReduceContext 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<InternalTimeSeries,InternalTimeSeries.InternalBucket>

getBuckets

public List<InternalTimeSeries.InternalBucket> getBuckets()

Description copied from interface: TimeSeries

The buckets created by this aggregation.

Specified by:

getBuckets in interface MultiBucketsAggregation

Specified by:

getBuckets in interface TimeSeries

Specified by:

getBuckets in class InternalMultiBucketAggregation<InternalTimeSeries,InternalTimeSeries.InternalBucket>

Returns:

The buckets of this aggregation.

getBucketByKey

public InternalTimeSeries.InternalBucket getBucketByKey(String key)

Specified by:

getBucketByKey in interface TimeSeries
