InternalTerms

protected InternalTerms(StreamInput in) throws java.io.IOException

Read from a stream.

Throws:

java.io.IOException

Method Details

doWriteTo

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

Specified by:

doWriteTo in class InternalAggregation

Throws:

java.io.IOException

writeTermTypeInfoTo

protected abstract void writeTermTypeInfoTo(StreamOutput out) throws java.io.IOException

Throws:

java.io.IOException

getBuckets

public abstract java.util.List<B> getBuckets()

Description copied from interface: Terms

Return the sorted list of the buckets in this terms aggregation.

Specified by:

getBuckets in interface MultiBucketsAggregation

Specified by:

getBuckets in interface Terms

Specified by:

getBuckets in class InternalMultiBucketAggregation<A extends InternalTerms<A,B>,B extends InternalTerms.Bucket<B>>

Returns:

The buckets of this aggregation.

getBucketByKey

public abstract B getBucketByKey(java.lang.String term)

Description copied from interface: Terms

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

Specified by:

getBucketByKey in interface Terms

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 B reduceBucket(java.util.List<B> 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<A extends InternalTerms<A,B>,B extends InternalTerms.Bucket<B>>

setDocCountError

protected abstract void setDocCountError(long docCountError)

getShardSize

protected abstract int getShardSize()

create

protected abstract A create(java.lang.String name, java.util.List<B> buckets, long docCountError, long otherDocCount)

createBucketsArray

protected abstract B[] createBucketsArray(int size)

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

equals

public boolean equals(java.lang.Object obj)

Overrides:

equals in class InternalAggregation

hashCode

public int hashCode()

Overrides:

hashCode in class InternalAggregation

doXContentCommon

protected static XContentBuilder doXContentCommon(XContentBuilder builder, ToXContent.Params params, long docCountError, long otherDocCount, java.util.List<? extends InternalTerms.Bucket> buckets) throws java.io.IOException

Throws:

java.io.IOException
