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

References lunchbox::Future< T >::wait().

+ Here is the call graph for this function:

template<class T>
bool lunchbox::Future< T >::operator> ( const T &  rhs)
inline

+ Here is the call graph for this function:

template<class T>
bool lunchbox::Future< T >::operator>= ( const T &  rhs)
inline

+ Here is the call graph for this function:

template<class T>
T lunchbox::Future< T >::wait ( const uint32_t  timeout_ = LB_TIMEOUT_INDEFINITE)
inline

Wait for the promise to be fullfilled.

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