UnrestrictedUpdateEvent< T > Class Template Reference

Detailed Description

template<typename T>
class drake::systems::UnrestrictedUpdateEvent< T >

This class represents an unrestricted update event.

It has an optional callback function to do custom handling of this event, and that can write updates to a mutable, non-null State object.
