Note

Unlike reinterpret_tag, retag enforces that the converted-to system tag be related to the converted-from system tag.

Template Parameters:

Tag – Tag shall be convertible to thrust::iterator_system<Iterator>::type, or thrust::iterator_system<Iterator>::type is a base type of Tag.
Iterator – Any iterator type.

Parameters:

iter – The iterator of interest.

Returns:

An iterator of unspecified type whose system tag is Tag and whose behavior is otherwise equivalent to iter.
