/**

* @class vtkStaticCellLinks
|
|
* @brief object represents upward pointers from points
|
|
* to list of cells using each point
|
|
*
|
|
* vtkStaticCellLinks is a supplemental object to vtkCellArray and
|
|
* vtkCellTypes, enabling access from points to the cells using the
|
|
* points. vtkStaticCellLinks is an array of links, each link represents a
|
|
* list of cell ids using a particular point. The information provided by
|
|
* this object can be used to determine cell neighbors and construct other
|
|
* local topological information. This class is a faster implementation of
|
|
* vtkCellLinks. However, it cannot be incrementally constructed; it is meant
|
|
* to be constructed once (statically) and must be rebuilt if the cells
|
|
* change.
|
|
*
|
|
* @warning
|
|
* This is a drop-in replacement for vtkCellLinks using static link
|
|
* construction. It uses the templated vtkStaticCellLinksTemplate class,
|
|
* instantiating vtkStaticCellLinksTemplate with a vtkIdType template
|
|
* parameter. Note that for best performance, the vtkStaticCellLinksTemplate
|
|
* class may be used directly, instantiating it with the appropriate id
|
|
* type. This class is also wrappable and can be used from an interpreted
|
|
* language such as Python.
