vtkStructuredAMRNeighbor & operator=(const vtkStructuredAMRNeighbor &N)
Overload assignment operator.
~vtkStructuredAMRNeighbor() override=default
Destructor.
std::string GetRelationShipString()
Returns the neighbor relationship as a string (useful for debugging).
void ComputeSendAndReceiveExtent(int gridRealExtent[6], int gridGhostedExtent[6], int neiRealExtent[6], int WholeExtent[6], const int N) override
Computes the SendExtent and RcvExtent for this neighbor.
vtkStructuredAMRNeighbor(const vtkStructuredAMRNeighbor &N)
Copy constructor.
vtkStructuredAMRNeighbor(const int gridLevel, const int neiID, const int neighborLevel, int gridOverlap[6], int neiOverlap[6], int orient[3], const int relationShip)
Custom constructor.
void GetReceiveExtentOnGrid(const int ng, int gridExtent[6], int ext[6])
Returns the receive extent w.r.t.
vtkStructuredAMRNeighbor()
Default constructor.
An internal, light-weight class used to store neighbor information.
