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.

Member Function Documentation

template<typename TNodeType >

Iterator itk::SparseFieldLayer< TNodeType >::Begin ( )

Create an object from an instance, potentially deferring to a factory. This method allows you to create an instance of an object that is exactly the same type as the referring object. This is useful in cases where an object has been cast back to a base class.
