public class NumericData
extends MetricData

A numeric metric data point. This class currently represents both raw and aggregated data; however, at some point we may subclasses for each of them.

Method Detail

getMetric

public Metric getMetric()

Currently not used. It wil be used for breaking up a metric time series into multiple partitions by date. For example, if we choose to partition by month, then all data collected for a given metric during October would go into one partition, and data collected during November would go into another partition. This will not impact writes, but it will make reads more complicated and potentially more expensive if we make the date partition too small.

Overrides:

getMetric in class MetricData

getValue

public double getValue()

The value of the raw data point. This should only be set for raw data. It should be null for aggregated data.

setValue

public NumericData setValue(double value)

getAggregatedValues

public Set<AggregatedValue> getAggregatedValues()

A set of the aggregated values that make up this aggregated data point. This should return an empty set for raw data.

addAggregatedValue

public NumericData addAggregatedValue(AggregatedValue aggregatedValue)

equals

public boolean equals(Object o)

Overrides:

equals in class MetricData

hashCode

public int hashCode()

Overrides:

hashCode in class MetricData

toString

public String toString()

Overrides:

toString in class Object
