Constructor Detail

PipelineAggregationSpec

public PipelineAggregationSpec(ParseField name,
                               Writeable.Reader<? extends PipelineAggregationBuilder> builderReader,
                               Writeable.Reader<? extends PipelineAggregator> aggregatorReader,
                               PipelineAggregator.Parser parser)

Specification of a PipelineAggregator.

Parameters:

name - holds the names by which this aggregation might be parsed. The ParseField.getPreferredName() is special as it is the name by under which the readers are registered. So it is the name that the PipelineAggregationBuilder and PipelineAggregator should return from NamedWriteable.getWriteableName().

builderReader - the reader registered for this aggregation's builder. Typically a reference to a constructor that takes a StreamInput

aggregatorReader - reads the PipelineAggregator from a stream

parser - reads the aggregation builder from XContent

PipelineAggregationSpec

public PipelineAggregationSpec(java.lang.String name,
                               Writeable.Reader<? extends PipelineAggregationBuilder> builderReader,
                               Writeable.Reader<? extends PipelineAggregator> aggregatorReader,
                               PipelineAggregator.Parser parser)

Specification of a PipelineAggregator.

Parameters:

name - name by which this aggregation might be parsed or deserialized. Make sure it is the name that the PipelineAggregationBuilder and PipelineAggregator should return from NamedWriteable.getWriteableName().

builderReader - the reader registered for this aggregation's builder. Typically a reference to a constructor that takes a StreamInput

aggregatorReader - reads the PipelineAggregator from a stream

parser - reads the aggregation builder from XContent

Method Detail

addResultReader

public SearchPlugin.PipelineAggregationSpec addResultReader(Writeable.Reader<? extends InternalAggregation> resultReader)

Add a reader for the shard level results of the aggregation with SearchPlugin.SearchExtensionSpec.getName()'s ParseField.getPreferredName() as the NamedWriteable.getWriteableName().

addResultReader

public SearchPlugin.PipelineAggregationSpec addResultReader(java.lang.String writeableName,
                                                            Writeable.Reader<? extends InternalAggregation> resultReader)

Add a reader for the shard level results of the aggregation.

getAggregatorReader

public Writeable.Reader<? extends PipelineAggregator> getAggregatorReader()

The reader for the PipelineAggregator.

getResultReaders

public java.util.Map<java.lang.String,Writeable.Reader<? extends InternalAggregation>> getResultReaders()

Get the readers that must be registered for this aggregation's results.
