Interface Interpolator

All Known Implementing Classes:

Interpolators.BaseInterpolator, Interpolators.Linear, Interpolators.Step

@Beta
public interface Interpolator

Defines how to interpolate a value between two other time values.

It is used to fill in empty timestamps in the result of CubeQuery when needed.

Method Summary

Modifier and Type	Method and Description
long	getMaxAllowedGap() Data points that are more than this many seconds apart will not cause interpolation to occur and will instead return 0 for any point in between.
long	interpolate(TimeValue start, TimeValue end, long ts) Given start and end TimeValues, and a time in-between the two, return a TimeValue for the in-between time.

Method Detail

interpolate

long interpolate(TimeValue start,
                 TimeValue end,
                 long ts)

Given start and end TimeValues, and a time in-between the two, return a TimeValue for the in-between time.

getMaxAllowedGap

long getMaxAllowedGap()

Data points that are more than this many seconds apart will not cause interpolation to occur and will instead return 0 for any point in between.
