Synopsis

basic operation on VectorContainer

Results

Output:

Code

C++

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

int
main(int, char *[])
{
  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;

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.

ITK Sphinx Examples:

Template Parameters
  • TElementIdentifier: An INTEGRAL type for use in indexing the vector.

  • TElement: The element type stored in the container.

See itk::VectorContainer for additional documentation.
