// .NAME vtkArrayIteratorTemplate - Implementation template for a array
// iterator.
//
// .SECTION Description
// This is implementation template for a array iterator. It only works
// with arrays that have a contiguous internal storage of values (as in
// vtkDataArray, vtkStringArray).
#ifndef vtkArrayIteratorTemplate_h
#define vtkArrayIteratorTemplate_h
#include "vtkCommonCoreModule.h" // For export macro
#include "vtkArrayIterator.h"

void PrintSelf(ostream& os, vtkIndent indent);
// Description:
// Set the array this iterator will iterate over.
// After Initialize() has been called, the iterator is valid
// so long as the Array has not been modified
// (except using the iterator itself).
// If the array is modified, the iterator must be re-intialized.

// Get the array.

// Must be called only after Initialize.

// Description:
// Must be called only after Initialize.

// Description:
// Sets the value at the index. This does not verify if the index is
// valid. The caller must ensure that id is less than the maximum
// number of values.
