Constructor Details

InternalComposite

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

Throws:

java.io.IOException

Method Details

doWriteTo

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

Specified by:

doWriteTo in class InternalAggregation

Throws:

java.io.IOException

doXContentBody

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

Specified by:

doXContentBody in class InternalAggregation

Throws:

java.io.IOException

getWriteableName

public java.lang.String getWriteableName()

Description copied from interface: NamedWriteable

Returns the name of the writeable object

Specified by:

getWriteableName in interface NamedWriteable

create

public InternalComposite create(java.util.List<InternalComposite.InternalBucket> newBuckets)

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<InternalComposite,InternalComposite.InternalBucket>

Parameters:

newBuckets - the buckets to use in the new Aggregation

Returns:

the new Aggregation

createBucket

public InternalComposite.InternalBucket createBucket(InternalAggregations aggregations, InternalComposite.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<InternalComposite,InternalComposite.InternalBucket>

Parameters:

aggregations - the aggregations for the new bucket

prototype - the bucket to use as a prototype

Returns:

the new bucket

getSize

public int getSize()

getBuckets

public java.util.List<InternalComposite.InternalBucket> getBuckets()

Specified by:

getBuckets in interface CompositeAggregation

Specified by:

getBuckets in interface MultiBucketsAggregation

Specified by:

getBuckets in class InternalMultiBucketAggregation<InternalComposite,InternalComposite.InternalBucket>

Returns:

The buckets of this aggregation.

afterKey

public java.util.Map<java.lang.String,java.lang.Object> afterKey()

Description copied from interface: CompositeAggregation

Returns the last key in this aggregation. It can be used to retrieve the buckets that are after these values. See CompositeAggregationBuilder.aggregateAfter(java.util.Map<java.lang.String, java.lang.Object>).

Specified by:

afterKey in interface CompositeAggregation

reduce

public InternalAggregation reduce(java.util.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

reduceBucket

protected InternalComposite.InternalBucket reduceBucket(java.util.List<InternalComposite.InternalBucket> 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<InternalComposite,InternalComposite.InternalBucket>

equals

public boolean equals(java.lang.Object obj)

Overrides:

equals in class InternalAggregation

hashCode

public int hashCode()

Overrides:

hashCode in class InternalAggregation
