Iterate on a Vector Container#

Synopsis#

basic operation on VectorContainer

Results#

Output:

[1, 2]
[2, 3]

Code#

C++#

#include "itkVectorContainer.h"
#include "itkPoint.h"

int
main()
{
  constexpr unsigned int Dimension = 2;
  using CoordType = double;

  using PointType = itk::Point<CoordType, Dimension>;
  using VectorContainerType = itk::VectorContainer<int, PointType>;

  PointType p0;
  p0[0] = 1.0;
  p0[1] = 2.0;

  PointType p1;
  p1[0] = 2.0;
  p1[1] = 3.0;

  auto points = VectorContainerType::New();
  points->Reserve(2);

  VectorContainerType::Iterator point = points->Begin();
  point->Value() = p0;

  ++point;
  point->Value() = p1;

  point = points->Begin();
  while (point != points->End())

    std::cout << point->Value() << std::endl;
    ++point;
  }

  return EXIT_SUCCESS;
}

Classes demonstrated#

template<typename TElementIdentifier, typename TElement> class VectorContainer : public itk::Object, private std::vector<TElement>

Define a front-end to the STL “vector” container that conforms to the IndexedContainerInterface.

This is a full-fleged Object, so there is modification time, debug, and reference count information.

Template Parameters

TElementIdentifier: An INTEGRAL type for use in indexing the vector.
TElement: The element type stored in the container.
