Constructor & Destructor Documentation

PointSpherical3D::PointSpherical3D ( )

Initialize point in the 3D cartesian space with coordinates (0, 0, 0).

This constructor is meant to be used when the programmer creates an instance of the high-level Python point, and allocates memory in the heap for storing the point. As one would normally think, this should be paired with a destructor that frees the allocated memory. However, when we free the memory in the destructor, the program aborts and states that the program tried to perform a double-free.

PointSpherical3D::PointSpherical3D ( double  x,
double  y,
double  z 
)

Initialize point in the 3D cartesian space with coordinates (x, y, z) as specified by the parameters.

This constructor is meant to be used when the programmer creates an instance of the high-level Python point, and allocates memory in the heap for storing the point. As one would normally think, this should be paired with a destructor that frees the allocated memory. However, when we free the memory in the destructor, the program aborts and states that the program tried to perform a double-free.

PointSpherical3D::PointSpherical3D ( PointSpherical_t *  initial_point,
unsigned int  initial_id = 0 
)

Initialize point in the spherical space from a ViennaGrid point.

What this makes is to set the pointer to point to the ViennaGrid point and thus solves the issue caused by the fact that the ViennaGrid point was being copied, thus not being able to get references to the points stored in the domain and thus not being able to modify them.

This constructor is meant to be used by the wrapper code when the programmer tries to get a reference to a point stored in a domain (not when they want to define a point on their own!), and does not allocate memory in the heap, thus elliminating the need for the constructor to free that memory when this constructor has been used. At first, one would think that it should be distinguished in some way when the object has been instantiated using this constructor or any other constructor in order for the destructor to only free when another constructor has been called, not this one. However, we have shown that no freeing action is need at all.

PointSpherical3D::PointSpherical3D ( PointSpherical_t &  initial_point,
unsigned int  initial_id = -1 
)

Initialize point in the spherical space from a ViennaGrid point by copying it.

This constructor is meant to be used by the wrapper code when the programmer runs an algorithm on points. Hence, it needs to allocate memory in the heap for the new ViennaGrid point.

As one would normally think, this should be paired with a destructor that frees the allocated memory. However, when we free the memory in the destructor, the program aborts and states that the program tried to perform a double-free.
