Detailed Description

template<class MeshType>
template<class SimplexPointerType>
class vcg::tri::Allocator< MeshType >::PointerUpdater< SimplexPointerType >

Accessory class to update pointers after eventual reallocation caused by adding elements.

This class is used whenever you trigger some allocation operation that can cause the invalidation of the pointers to mesh elements. Typical situations are when you are allocating new vertexes, edges, halfedges of faces or when you compact their containers to get rid of deleted elements. This object allows you to update an invalidate pointer immediately after an action that invalidate it.

Note:

It can also be used to prevent any update of the various internal pointers caused by an invalidation. This can be useful in case you are building all the internal connections by hand as it happens in a importer;
