struct result_type_helper¶ Helper struct determining the result’s type.
This helper struct provides type definitions to extract the correct propagation result type from a given TrackParameter type and an ActionList.
Note
The result_type_helper struct and the action_list_t_result_t are here to allow a look’n’feel of this class like the Propagator itself
- Template Parameters
parameters_t – Type of final track parameters
action_list_t – List of propagation action types
Public Types
-
using this_result_type = PropagatorResult<parameters_t, args...>¶
Propagation result type for an arbitrary list of additional propagation results.
- Template Parameters
args – Parameter pack specifying additional propagation results
-
using type = typename action_list_t::template result_type<this_result_type>¶
Propagation result type derived from a given action list.
