#include <itkSparseFieldLayer.h>

Detailed Description

template<typename TNodeType>
class itk::SparseFieldLayer< TNodeType >

A very simple linked list that is used to manage nodes in a layer of a sparse field level-set solver.

This class implements a very simple linked list that is used to manage nodes in a layer of a sparse field level-set solver. For more information on the sparse field level-set solver, see documentation for itk::SparseFieldLevelSetImageFilter.
IMPORTANT!
One important and distinctive feature of this list implementation (in fact, the entire reason for this object's existence) is that no memory allocation/deallocation occurs during linking or unlinking of nodes. The nodes themselves are expected to carry the appropriate "Next" & "Previous" fields used to link. Guaranteeing that no calls to new or delete are ever made for normal list operations allows us to safely use this class in a multithread environment without incurring penalties from heap contention among threads. Because no allocation/deallocation occurs, it is entirely up to the calling program to manage the allocating and freeing of the list nodes.
