Detailed Description

template<typename T>
class BS::multi_future< T >

A helper class to facilitate waiting for and/or getting the results of multiple futures at once.

Template Parameters

T	The return type of the futures.

Constructor & Destructor Documentation

multi_future()

multi_future ( const size_t  num_futures_ = 0 )

inline

Construct a multi_future object with the given number of futures.

Parameters

num_futures_

The desired number of futures to store.

Member Function Documentation

get()

std::conditional_t<std::is_void_v<T>, void, std::vector<T> > get ( )

inline

Get the results from all the futures stored in this multi_future object, rethrowing any stored exceptions.

Returns

If the futures return void, this function returns void as well. Otherwise, it returns a vector containing the results.

operator[]()

std::future<T>& operator[] ( const size_t  i )

inline

Get a reference to one of the futures stored in this multi_future object.

Parameters

i	The index of the desired future.

Returns

The future.

push_back()

void push_back ( std::future< T >  future )

inline

Append a future to this multi_future object.

Parameters

future

The future to append.

size()

size_t size ( ) const

inline

Get the number of futures stored in this multi_future object.

Returns

The number of futures.
