org.robwork.sdurw_trajectory.CubicSplineInterpolator_d_fPtr

public class CubicSplineInterpolator_d_fPtr
extends java.lang.Object

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

Constructor Summary

Constructors

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

CubicSplineInterpolator_d_fPtr

public CubicSplineInterpolator_d_fPtr(long cPtr,
                                      boolean cMemoryOwn)

CubicSplineInterpolator_d_fPtr

public CubicSplineInterpolator_d_fPtr()

Default constructor yielding a NULL-pointer.

CubicSplineInterpolator_d_fPtr

public CubicSplineInterpolator_d_fPtr(CubicSplineInterpolator_d_f ptr)

Do not take ownership of ptr.

ptr can be null.

The constructor is implicit on purpose.

Method Detail

getCPtr

isShared

public boolean isShared()

check if this Ptr has shared ownership or none
ownership

Returns:

true if Ptr has shared ownership, false if it has no ownership.

isNull
