Method Detail

registerStreams

public static void registerStreams()

getValue

public long getValue()

Specified by:

getValue in interface ValueCount

Returns:

The count

value

public double value()

Specified by:

value in interface NumericMetricsAggregation.SingleValue

type

public InternalAggregation.Type type()

Specified by:

type in class InternalAggregation

Returns:

The InternalAggregation.Type of this aggregation

reduce

public InternalAggregation reduce(InternalAggregation.ReduceContext reduceContext)

Description copied from class: InternalAggregation

Reduces the given addAggregation to a single one and returns it. In most cases, the assumption will be the all given addAggregation are of the same type (the same type as this aggregation). For best efficiency, when implementing, try reusing an existing get instance (typically the first in the given list) to save on redundant object construction.

Specified by:

reduce in class InternalAggregation

              throws IOException

Specified by:

readFrom in interface Streamable

Throws:

IOException

writeTo

public void writeTo(StreamOutput out)
             throws IOException

Specified by:

writeTo in interface Streamable

Throws:

IOException

doXContentBody

                               throws IOException

Specified by:

doXContentBody in class InternalAggregation

Throws:

IOException
