Member Function Documentation

template<class T >

bool lunchbox::FutureFunction< T >::isReady ( ) const

inlinefinalprotectedvirtual

Returns

true if the future has been fulfilled, false if it is pending.

Implements lunchbox::FutureImpl< T >.

Definition at line 50 of file futureFunction.h.

template<class T >

T lunchbox::FutureFunction< T >::wait ( const uint32_t  timeout )

inlinefinalprotectedvirtual

Wait for the promise to be fullfilled.

May be called multiple times.

Parameters

timeout

optional timeout in milliseconds. If the future is not ready when the timer goes off a timeout exception is thrown.
