Public Functions

template<typename StoreT>
result(StoreT &store)

Parameters

  • store: collector

template<typename CombinatorT>
void done(CombinatorT cmb)

attach another subtask as done callback which will be executed once this subtask finishes

Parameters

  • cmb: next subtask

void required(bool flag)

mark the activity as required or optional

Parameters

  • flag:

void cancel_if(cancel_if_ftor f)

Force cancelation of the activity even after it is successful to stop propagating to the next activities

Parameters

  • f: callback which should return true to signal cancelation
