Constructor Details

InternalValueCount

public InternalValueCount(String name,
 long value,
 Map<String,Object> metadata)

InternalValueCount

public InternalValueCount(StreamInput in)
                   throws IOException

Read from a stream.

Throws:

IOException

Method Details

doWriteTo

protected void doWriteTo(StreamOutput out)
                  throws IOException

Specified by:

doWriteTo in class InternalAggregation

Throws:

IOException

getWriteableName

public String getWriteableName()

Description copied from interface: NamedWriteable

Returns the name of the writeable object

Specified by:

getWriteableName in interface NamedWriteable

getValue

public long getValue()

Specified by:

getValue in interface ValueCount

Returns:

The count

value

public double value()

Specified by:

value in interface NumericMetricsAggregation.SingleValue

reduce

public InternalAggregation reduce(List<InternalAggregation> aggregations,
 InternalAggregation.ReduceContext reduceContext)

Description copied from class: InternalAggregation

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

Specified by:

reduce in class InternalAggregation
