## Detailed Description

### template<typename Body>
class tbb::parallel_while< Body >

Parallel iteration over a stream, with optional addition of more work.

The Body b has the requirement:
"b(v)"
"b.argument_type"
where v is an argument_type

## Member Function Documentation

template<typename Body >

void tbb::parallel_while< Body >::add | ( | const value_type & | item) |  |

Add a work item while running.

Should be executed only by body.apply or a thread spawned therefrom.

template<typename Body >
template<typename Stream >

void tbb::parallel_while< Body >::run | ( | Stream & | stream,
|  | const Body & | body
| ) |  |

Apply body.apply to each item in the stream.

A Stream s has the requirements
"S::value_type"
"s.pop_if_present(value) is convertible to bool
