// .NAME vtkTypedArray - Provides a type-specific interface to N-way arrays
//
// .SECTION Description
// vtkTypedArray provides an interface for retrieving and updating data in an
// arbitrary-dimension array. It derives from vtkArray and is templated on the
// type of value stored in the array.
//
// Methods are provided for retrieving and updating array values based either
// on their array coordinates, or on a 1-dimensional integer index. The latter
// approach can be used to iterate over the values in an array in arbitrary order,
// which is useful when writing filters that operate efficiently on sparse arrays
// and arrays that can have any number of dimensions.
//
// Special overloaded methods provide simple access for arrays with one, two, or
// three dimensions.
//
// .SECTION See Also
// vtkArray, vtkDenseArray, vtkSparseArray
//
// .SECTION Thanks
// Developed by Timothy M. Shead (tshead@sandia.gov) at Sandia National Laboratories.
