T get()const;	(1)	(único membro da modelo shared_future genérico) (desde C++11)
T& get()const;	(2)	(único membro da shared_future<T&> especialização modelo) (desde C++11)
void get()const;	(3)	(único membro da shared_future<void> especialização modelo) (desde C++11)

O método get espera até que o shared_future tem um resultado válido e (dependendo do modelo é usado) recupera. Ele efetivamente chama wait(), a fim de aguardar o resultado.

Original:

The get method waits until the shared_future has a valid result and (depending on which template is used) retrieves it. It effectively calls wait() in order to wait for the result.
