Method Details

getWeight

public org.apache.lucene.search.Weight getWeight()

Returns the Weight for this filter aggregation, creating it if necessary. This is done lazily so that the Weight is only created if the aggregation collects documents reducing the overhead of the aggregation in the case where no documents are collected. Note that as aggregations are initialsed and executed in a serial manner, no concurrency considerations are necessary here.

createInternal

public Aggregator createInternal(SearchContext searchContext, Aggregator parent, boolean collectsFromSingleBucket, java.util.List<PipelineAggregator> pipelineAggregators, java.util.Map<java.lang.String,java.lang.Object> metaData) throws java.io.IOException

Specified by:

createInternal in class AggregatorFactory

Throws:

java.io.IOException
