Detailed Description#

template<typename T>
class AComplexFutureOperation< T >

Template Parameters

T	future type AFuture<T> (void is default)

AComplexFutureOperation is used to handle results and errors of multiple sequential futures.

AComplexFutureOperation is intended to construct a future with makeFuture(). makeFuture() must be called.

If AComplexFutureOperation get destroyed, it reports error to it's future if it does not have a result. AComplexFutureOperation should be carried with AFuture::onSuccess callbacks of other futures or any other callback-based structure, hence the destruction without result is treated as an error.

Member Function Documentation#

makeFuture()#

template<typename T>

AFuture< T > AComplexFutureOperation< T >::makeFuture ( )

inlinenodiscardnoexcept

AFuture<T> can be created only once.

operator<<()#

template<typename T>

template<typename OtherT>

AComplexFutureOperation & AComplexFutureOperation< T >::operator<< ( AFuture< OtherT > rhs )

inline

Parameters

rhs	other future

Stores other AFuture to internal AAsyncHolder storage. Passes rhs's onError calls to AComplexFutureOperation's future, if it does not have result.

supplyValue()#

template<typename T>

void AComplexFutureOperation< T >::supplyValue ( T value )

inline

Parameters

value

operation
