Detailed Description

template<typename TIds>
class vtkStaticCellLinksTemplate< TIds >

object represents upward pointers from points to list of cells using each point (template implementation)

vtkStaticCellLinksTemplate is a supplemental object to vtkCellArray and vtkCellTypes, enabling access to the list of cells using each point. vtkStaticCellLinksTemplate 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 neighbors (e.g., face neighbors, edge 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.

This is a templated implementation for vtkStaticCellLinks. The reason for the templating is to gain performance and reduce memory by using smaller integral types to represent ids. For example, if the maximum id can be represented by an int (as compared to a vtkIdType), it is possible to reduce memory requirements by half and increase performance. This templated class can be used directly; alternatively the non-templated class vtkStaticCellLinks can be used for convenience; although it uses vtkIdType and so will lose some speed and memory advantages.
