#include <itkOffset.h>
Represent a n-dimensional offset between two n-dimensional indexes of n-dimensional image.
Offset is a templated class to represent a multi-dimensional offset, i.e. (i,j,k,...). Offset is templated over the dimension of the space. ITK assumes the first element of a size (bounds) is the fastest moving index.
For efficiency, Offset does not define a default constructor, a copy constructor, or an operator=. We rely on the compiler to provide efficient bitwise copies.
Offset is an "aggregate" class. Its data is public (m_InternalArray) allowing for fast and convenient instantiations/assignments.
The following syntax for assigning an aggregate type like this is allowed/suggested:
Offset<3> var{{ 256, 256, 20 }}; // Also prevent narrowing conversions Offset<3> var = {{ 256, 256, 20 }};
The doubled braces {{ and }} are required to prevent ‘gcc -Wall’ (and perhaps other compilers) from complaining about a partly bracketed initializer.
As an aggregate type that is intended to provide highest performance characteristics, this class is not appropriate to inherit from, so setting this struct as final.
