Class Interpolators.BaseInterpolator

java.lang.Object

io.cdap.cdap.api.dataset.lib.cube.Interpolators.BaseInterpolator

All Implemented Interfaces:

Interpolator

Direct Known Subclasses:

Interpolators.Linear, Interpolators.Step

Enclosing class:

Interpolators

public abstract static class Interpolators.BaseInterpolator
extends Object
implements Interpolator

Return 0 if the time between data points is above a give limit, or if the point to interpolate is too far before the first point, or too far after the last point.

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.
protected abstract long	limitedInterpolate(TimeValue start, TimeValue end, long ts)
