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.

Return 1 if this class is the same type of (or a subclass of) the named class.
Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Methods invoked by print to print information about the object including superclasses.
Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.
Reimplemented from vtkAbstractCellLinks.

overridevirtual |
Build the link list array.
All subclasses of vtkAbstractCellLinks must support this method.
Implements vtkAbstractCellLinks.
void vtkCellLinks::BuildLinks | ( | vtkDataSet * | data, |
vtkCellArray * | Connectivity | ||
) |
Build the link list array with a provided connectivity array.
Allocate the specified number of links (i.e., number of points) that will be built.
void vtkCellLinks::Initialize | ( | ) |
Clear out any previously allocated data structures.
Get a link structure given a point id.
Definition at line 88 of file vtkCellLinks.h.

Get the number of cells using the point specified by ptId.
Definition at line 93 of file vtkCellLinks.h.
Return a list of cell ids using the point.
Definition at line 98 of file vtkCellLinks.h.
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 201 of file vtkCellLinks.h.
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 216 of file vtkCellLinks.h.
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).
Definition at line 236 of file vtkCellLinks.h.
Change the length of a point's link list (i.e., list of cells using a point) by the size specified.
Definition at line 242 of file vtkCellLinks.h.
void vtkCellLinks::Squeeze | ( | ) |
Reclaim any unused memory.
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.
