#include <itkNeighborhoodAllocator.h>

Detailed Description

template<typename TPixel>
class itk::NeighborhoodAllocator< TPixel >

A memory allocator for use as the default allocator type in Neighborhood.

This is a memory allocator for use as the default allocator type in Neighborhood. The API is designed to mimic that of vnl_vector so that vnl_vector can also be used as an allocator for Neighborhood.

The decision to create this allocator with the vnl_vector api (versus using an STL allocator and wrapping the vnl_vector API) was made because the STL allocator API is not guaranteed stable at this time.

Member Typedef Documentation

◆ const_iterator

template<typename TPixel>
using itk::NeighborhoodAllocator< TPixel >::const_iterator = const TPixel *

Definition at line 55 of file itkNeighborhoodAllocator.h.

◆ iterator

template<typename TPixel>
using itk::NeighborhoodAllocator< TPixel >::iterator = TPixel *

Iterator support. Note that the naming of the type alias is on purpose. itk::Neighborhood makes reference to the allocator, which because it may be vnl or other type, uses the lower case/underscore forms iterator and const_iterator.

Definition at line 54 of file itkNeighborhoodAllocator.h.

◆ Self

template<typename TPixel>
using itk::NeighborhoodAllocator< TPixel >::Self = NeighborhoodAllocator

Standard class type aliases.
