[Insight-developers] reimplemented doubly linked list vs std::list ?

[Arnaud GELAS]

Bill, Luis,

In ITK, some people have reimplemented a doubly linked list, e.g. 
itkSparseFieldLayer.h

Is there a good reason to reimplement such a data structure rather than 
using a std::list<> ?
speed? memory management?

This class is used in different locations of the toolkit; while you 
would expect it to appear with sparse level set (Its name is quite 
misleading especially when you see it in CannyEdgeDetectionImageFilter 
or AntiAliasBinaryImageFilter).

Thanks,
Arnaud
