Constructor Detail

AggregationSpec

public AggregationSpec(ParseField name,
                       Writeable.Reader<? extends AggregationBuilder> reader,
                       Aggregator.Parser parser)

Specification for an Aggregation.

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 reader is registered. So it is the name that the AggregationBuilder should return from NamedWriteable.getWriteableName().

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

parser - the parser the reads the aggregation builder from xcontent

AggregationSpec

public AggregationSpec(java.lang.String name,
                       Writeable.Reader<? extends AggregationBuilder> reader,
                       Aggregator.Parser parser)

Specification for an Aggregation.

Parameters:

name - the name by which this aggregation might be parsed or deserialized. Make sure that the AggregationBuilder returns this from NamedWriteable.getWriteableName().

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

parser - the parser the reads the aggregation builder from xcontent

Method Detail

addResultReader

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

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

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.
