array_view::get_ref Method

  • Article

Get a reference to the element indexed by _Index. Unlike the other indexing operators for accessing the array_view on the CPU, this method does not implicitly synchronize this array_view's contents to the CPU. After accessing the array_view on a remote location or performing a copy operation involving this array_view users are responsible to explicitly synchronize the array_view to the CPU before calling this method. Failure to do so results in undefined behavior.
