Constructor Details

InternalScriptedMetric

public InternalScriptedMetric(StreamInput in) throws java.io.IOException

Read from a stream.

Throws:

java.io.IOException

Method Details

doWriteTo

protected void doWriteTo(StreamOutput out) throws java.io.IOException

Specified by:

doWriteTo in class InternalAggregation

Throws:

java.io.IOException

getWriteableName

public java.lang.String getWriteableName()

Description copied from interface: NamedWriteable

Returns the name of the writeable object

Specified by:

getWriteableName in interface NamedWriteable

aggregation

public java.lang.Object aggregation()

Description copied from interface: ScriptedMetric

The result of the aggregation. The type of the object depends on the aggregation that was run.

Specified by:

aggregation in interface ScriptedMetric

reduce

public InternalAggregation reduce(java.util.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

getProperty

public java.lang.Object getProperty(java.util.List<java.lang.String> path)

Specified by:

getProperty in class InternalAggregation

doXContentBody

public XContentBuilder doXContentBody(XContentBuilder builder, ToXContent.Params params) throws java.io.IOException

Specified by:

doXContentBody in class InternalAggregation

Throws:

java.io.IOException

equals

public boolean equals(java.lang.Object obj)

Overrides:

equals in class InternalAggregation

hashCode

public int hashCode()

Overrides:
