Introduction

vtkCellLinks maps each point to the cells that reference it.

Methods

addCellReference

Add a reference from a point to a cell.

Argument	Type	Required	Description
cellId	Number	Yes	Cell id.
ptId	Number	Yes	Point id.

allocate

Allocate storage for a number of links (typically the number of points).

Argument	Type	Required	Description
numLinks	Number	Yes	Number of point links to allocate.
extSize=1000	Number	No	Growth factor used for future extensions.

allocateLinks

Allocate per-point cell-id arrays based on precomputed link counts.

Argument	Type	Required	Description
n	Number	Yes	Number of links (points).

buildLinks

Build the link list array from the input dataset. The resulting structure maps each point id to the cells that reference it.

cells

Cell ids that use the point.

deepCopy

Deep-copy from another cell-links instance.

Argument	Type	Required	Description
src		Yes	Source object.

deletePoint

Delete a point by removing all links to using cells.

Argument	Type	Required	Description
ptId	Number	Yes	Point id.

extend

Method used to decorate a given object (publicAPI+model) with vtkCellLinks characteristics.

Argument	Type	Required	Description
publicAPI		Yes	object on which methods will be bounds (public)
model		Yes	object on which data structure will be bounds (protected)
initialValues	ICellLinksInitialValues	No	(default: {})

getCells

Return the list of cell ids that use the point.

Argument	Type	Required	Description
ptId	Number	Yes	Point id.

getLink

Get the full link structure for a point id.

Argument	Type	Required	Description
ptId	Number	Yes	Point id.

getNcells

Get the number of cells using the point.

Argument	Type	Required	Description
ptId	Number	Yes	Point id.

incrementLinkCount

Increment the count of cells using a point.

Argument	Type	Required	Description
ptId	Number	Yes	Point id.

initialize

Clear out previously allocated link structures.

insertCellReference

Insert a cell id into a point's cell-id list at a specific position.

Argument	Type	Required	Description
ptId	Number	Yes	Point id.
pos	Number	Yes	Position inside the point's list.
cellId	Number	Yes	Cell id.

insertNextCellReference

Append a cell id to the point's cell-id list.

Argument	Type	Required	Description
ptId	Number	Yes	Point id.
cellId	Number	Yes	Cell id.

insertNextPoint

Insert a new point entry into the links structure.

Argument	Type	Required	Description
numLinks	Number	Yes	Initial size of the point's cell-id list.

ncells

Number of cells using the point.

newInstance

Method used to create a new instance of vtkCellLinks.

Argument	Type	Required	Description
initialValues	ICellLinksInitialValues	No	for pre-setting some of its content

removeCellReference

Remove the reference from a point to a cell.

Argument	Type	Required	Description
cellId	Number	Yes	Cell id.
ptId	Number	Yes	Point id.

reset

Reset to an empty state without freeing memory.

resizeCellList

Resize a point's cell-id list.

Argument	Type	Required	Description
ptId	Number	Yes	Point id.
size	Number	Yes	New list size.

squeeze

Reclaim unused memory.
