Method Detail

getWeights

public org.apache.lucene.search.Weight[] getWeights()

Returns the Weights for this filter aggregation, creating it if necessary. This is done lazily so that the Weights are 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(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<FiltersAggregatorFactory>

Throws:

java.io.IOException
