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

- Revision:
- 1.29
vtkCellLinks is a supplemental object to vtkCellArray and vtkCellTypes, enabling access from points to the cells using the points. vtkCellLinks is a list of Links, each link represents a dynamic list of cell id's using the point. The information provided by this object can be used to determine neighbors and construct other local topological information.

Return a list of cell ids using the point. Definition at line 84 of file vtkCellLinks.h. References vtkIdType. Referenced by vtkPolyData::GetPointCells(). |
|
|
Insert a new point into the cell-links data structure. The size parameter is the initial size of the list. |

|
Insert a cell id into the list of cells (at the end) using the cell id provided. (Make sure to extend the link list (if necessary) using the method ResizeCellList().)

Delete point (and storage) by destroying links to using cells. Definition at line 163 of file vtkCellLinks.h. References Array, vtkCellLinks::Link::cells, vtkCellLinks::Link::ncells, and vtkIdType. Referenced by vtkPolyData::DeletePoint(). |
|
||||||||||||
|
Delete the reference to the cell (cellId) from the point (ptId). This removes the reference to the cellId from the cell list, but does not resize the list (recover memory with ResizeCellList(), if necessary). Definition at line 176 of file vtkCellLinks.h. References Array, vtkCellLinks::Link::cells, vtkCellLinks::Link::ncells, and vtkIdType. Referenced by vtkPolyData::RemoveCellReference(). |
|
||||||||||||
|
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).

Change the length of a point's link list (i.e., list of cells using a point) by the size specified. Definition at line 200 of file vtkCellLinks.h. References Array, vtkCellLinks::Link::cells, vtkCellLinks::Link::ncells, and vtkIdType. Referenced by vtkPolyData::ResizeCellList(). |
|
|
Reclaim any unused memory. |
|
|
Reset to a state of no entries without freeing the memory. |
|
|
Return the memory in kilobytes 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. |
|
|
Standard DeepCopy method. Since this object contains no reference to other objects, there is no ShallowCopy. |
|
|
Increment the count of the number of cells using the point. Definition at line 135 of file vtkCellLinks.h. References vtkIdType. |
