org.robwork.sdurw_trajectory.CubicSplineInterpolatorVector3DCPtr

public class CubicSplineInterpolatorVector3DCPtr
extends java.lang.Object

Ptr stores a pointer and optionally takes ownership of the value.

Constructor Summary

Constructors

Constructor	Description
CubicSplineInterpolatorVector3DCPtr()	Default constructor yielding a NULL-pointer.
CubicSplineInterpolatorVector3DCPtr(long cPtr, boolean cMemoryOwn)
CubicSplineInterpolatorVector3DCPtr(CubicSplineInterpolatorVector3D ptr)	Do not take ownership of ptr. ptr can be null. The constructor is implicit on purpose.

Method Summary

Modifier and Type	Method	Description
CubicSplineInterpolatorVector3D	__ref__()	Dereferencing operator.
Vector3D	ddx(double t)	Note: The second derivative is a 1-degree polynomial: \bf{df}(t)= 2\cdot \bf{c} + 6\cdot \bf{d}\cdot t
void	delete()
CubicSplineInterpolatorVector3D	deref()	The pointer stored in the object.
double	duration()
Vector3D	dx(double t)	Note: The derivative is a 2-degree polynomial: \bf{df}(t)= \bf{b} + 2\cdot \bf{c}\cdot t + 3\cdot \bf{d}\cdot t^2
boolean	equals(CubicSplineInterpolatorVector3D p)
static long	getCPtr(CubicSplineInterpolatorVector3DCPtr obj)
CubicSplineInterpolatorVector3D	getDeref()	Member access operator.
boolean	isNull()	checks if the pointer is null
boolean	isShared()	check if this Ptr has shared ownership or none ownership
Vector3D	x(double t)	Note: The cubic polynomial is given by a 3-degree polynomial: \bf{f}(t)= \bf{a} + \bf{b}\cdot t + \bf{c}\cdot t^2 \bf{d}\cdot t^3

CubicSplineInterpolatorVector3DCPtr

public CubicSplineInterpolatorVector3DCPtr()

Default constructor yielding a NULL-pointer.

CubicSplineInterpolatorVector3DCPtr

public CubicSplineInterpolatorVector3DCPtr(CubicSplineInterpolatorVector3D ptr)

Do not take ownership of ptr.

ptr can be null.

The constructor is implicit on purpose.

Method Detail
