getStartEpochNanos

public long getStartEpochNanos()

Description copied from interface: PointData

Returns the start time of the aggregation in epoch nanos.

Specified by:

getStartEpochNanos in interface PointData

getEpochNanos

public long getEpochNanos()

Description copied from interface: PointData

Returns the end time of the aggregation in epoch nanos.

Specified by:

getEpochNanos in interface PointData

getAttributes

public Attributes getAttributes()

Description copied from interface: PointData

Returns the attributes of the aggregation.

Specified by:

getAttributes in interface PointData

getSum

public double getSum()

Description copied from interface: HistogramPointData

The sum of all measurements recorded.

Specified by:

getSum in interface HistogramPointData

Returns:

the sum of recorded measurements.

getCount

public long getCount()

Description copied from interface: HistogramPointData

The number of measurements taken.

Specified by:

getCount in interface HistogramPointData

Returns:

the count of recorded measurements.

hasMin

public boolean hasMin()

Description copied from interface: HistogramPointData

Return true if HistogramPointData.getMin() is set.

Specified by:

hasMin in interface HistogramPointData

getMin

public double getMin()

Description copied from interface: HistogramPointData

The min of all measurements recorded, if HistogramPointData.hasMin() is true. If HistogramPointData.hasMin() is false, the response should be ignored.

Specified by:

getMax in interface HistogramPointData

getBoundaries

public List<Double> getBoundaries()

Description copied from interface: HistogramPointData

The bucket boundaries. For a Histogram with N defined boundaries, e.g, [x, y, z]. There are N+1 counts: (-inf, x], (x, y], (y, z], (z, +inf).

Specified by:
