Detailed Description

template<typename ArrayHandleType>
class vtkm::cont::ArrayHandleView< ArrayHandleType >

Provided a windowed view into a vtkm::cont::ArrayHandle.

ArrayHandleView is a fancy array that wraps around another ArrayHandle and reindexes it to provide access to a specified region of values in the array. This view is specified using the offset to the first index and the length of the entries to view.
