Detailed Description

Simulation properties for a single track.

TODO: refactor "reset_step_limit" and the along/post-step action setters to validate that setting a new action may only increase the ID (if it's explicit) and can only reduce the step limit. See StatusCheckExecutor . Maybe we also need to reconsider having separate along- and post-step action IDs: perhaps find a way to have a "step limit action" and a "next action"?

Member Function Documentation

◆ post_step_action()

CELER_FUNCTION void celeritas::SimTrackView::post_step_action ( ActionId  action)
inline

Force the limiting action to take.

This is used by intermediate kernels (such as discrete_select_track ) that dispatch to another kernel action before the end of the step without changing the step itself.

◆ reset_step_limit()

CELER_FUNCTION void celeritas::SimTrackView::reset_step_limit ( StepLimit const &  sl)
inline

Reset step limiter at the beginning of a step.

The action can be unset if and only if the step is infinite.

◆ step_limit()

CELER_FUNCTION bool celeritas::SimTrackView::step_limit ( StepLimit const &  sl)
inline

Limit the step by this distance and action.

If the step limits are the same, the original action is retained.

Returns
Whether the given limit is the new limit.
