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 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.

void vtkCellLinks::PrintSelf ( ostream &  os,

void vtkCellLinks::Allocate ( vtkIdType  numLinks,
vtkIdType  ext = 1000 
)

Allocate the specified number of links (i.e., number of points) that will be built.

Link& vtkCellLinks::GetLink ( vtkIdType  ptId)
inline

Get a link structure given a point id.

Definition at line 56 of file vtkCellLinks.h.

unsigned short vtkCellLinks::GetNcells ( vtkIdType  ptId)
inline

Get the number of cells using the point specified by ptId.

Definition at line 59 of file vtkCellLinks.h.

void vtkCellLinks::BuildLinks ( vtkDataSet *  data)

Build the link list array.

void vtkCellLinks::BuildLinks ( vtkDataSet *  data,
vtkCellArray Connectivity 
)

Build the link list array.

vtkIdType* vtkCellLinks::GetCells ( vtkIdType  ptId)
inline

Return a list of cell ids using the point.

Definition at line 68 of file vtkCellLinks.h.

vtkIdType vtkCellLinks::InsertNextPoint ( int  numLinks)

Insert a new point into the cell-links data structure. The size parameter is the initial size of the list.

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

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().)

Definition at line 156 of file vtkCellLinks.h.

void vtkCellLinks::DeletePoint ( vtkIdType  ptId)
inline

Delete point (and storage) by destroying links to using cells.

Definition at line 148 of file vtkCellLinks.h.

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

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 163 of file vtkCellLinks.h.

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).

Definition at line 183 of file vtkCellLinks.h.

void vtkCellLinks::ResizeCellList ( vtkIdType  ptId,
int  size 
)
inline

Change the length of a point's link list (i.e., list of cells using a point) by the size specified.

Definition at line 189 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 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.

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)
inlineprotected

Increment the count of the number of cells using the point.

Definition at line 119 of file vtkCellLinks.h.

void vtkCellLinks::AllocateLinks ( vtkIdType  n)
protected
void vtkCellLinks::InsertCellReference ( vtkIdType  ptId,
unsigned short  pos,
vtkIdType  cellId

Insert a cell id into the list of cells using the point.
