Name	Remarks	Include Path
FPiecewiseCurve Derivative()	Compute the integral of this curve (ie, the slope of this curve), returning the result as another piecewise curve	Channels/MovieScenePiecewiseCurve.h
bool Evaluate ( FFrameTime Time, double& OutResult ) const	Evaluate this curve at the specified time	Channels/MovieScenePiecewiseCurve.h
Interpolation::FCachedInterpolation GetInterpolationForTime ( FFrameTime Time ) const	Get the interpolation for a specific time	Channels/MovieScenePiecewiseCurve.h
FPiecewiseCurve Integral()	Compute the integral of this curve (ie, the cumulative area under this curve), returning the result as another piecewise curve	Channels/MovieScenePiecewiseCurve.h
TOptional< FFrameTime > InverseEvaluate ( double Value, FFrameTime TimeHint, EInverseEvaluateFlags Flags ) const	Solve this curve for a given (y).	Channels/MovieScenePiecewiseCurve.h
bool InverseEvaluateBetween ( double Value, FFrameTime StartTime, FFrameTime EndTime, const TFunctionRef< bool(FFrameTime)>& Visitor ) const	Solve this curve for a given (y), only considering solutions that lie within a certain range.	Channels/MovieScenePiecewiseCurve.h
void Offset ( double Amount )	Offset this curve in the (y) direction by a certain amount.	Channels/MovieScenePiecewiseCurve.h
