# reset_nobserver_impl

A nobserver to handle “out of band” reset events sent between layers. When the triggering event is detected, a resetattime event is sent to targets; the relevant time is extracted from a sync object.

## add_target

    some_rno add_target target

Add `target` as a layer to be reset when a trigger event occurs.

## add_sync

    some_rno add_sync sync

Set `sync` as the layer whose current time should be conveyed as the appropriate time for reset to target layers. Under normal circumstances, this should be the layer providing the trigger pattern.
