Detailed Description

object represents upward pointers from points to list of cells using each point

vtkCellLinks is a supplemental object to vtkCellArray and vtkCellTypes, enabling access from points to the cells using the points. vtkCellLinks is a list of cell ids, each such link representing a dynamic list of cell ids using the point. The information provided by this object can be used to determine neighbors and construct other local topological information.

Warning
Note that this class is designed to support incremental link construction. More efficient cell links structures can be built with vtkStaticCellLinks (and vtkStaticCellLinksTemplate). However these other classes are typically meant for one-time (static) construction.

void vtkCellLinks::AddCellReference ( vtkIdType  cellId,
vtkIdType  ptId 
)
inline

Add the reference to the cell (cellId) from the point (ptId).

This adds a reference to the cellId from the cell list, but does not resize the list (extend memory with ResizeCellList(), if necessary).

void vtkCellLinks::Reset ( )

Reset to a state of no entries without freeing the memory.

unsigned long vtkCellLinks::GetActualMemorySize ( )

Return the memory in kibibytes (1024 bytes) consumed by this cell links array.

Used to support streaming and reading/writing data. The value returned is guaranteed to be greater than or equal to the memory required to actually represent the data represented by this object. The information returned is valid only after the pipeline has been updated.

void vtkCellLinks::DeepCopy ( vtkCellLinks src)

Standard DeepCopy method.

Since this object contains no reference to other objects, there is no ShallowCopy.

void vtkCellLinks::IncrementLinkCount ( vtkIdType  ptId)
