SystemVisitor< T > Class Template Reference

Detailed Description

template<typename T>
class maliput::drake::systems::SystemVisitor< T >

Provides a "Visitor Pattern" for System and Diagram.

Rather than adding more virtual methods to the System base class, or performing a dynamic_cast to test if a System is a Diagram, you may use the visitor pattern enabled by this class, e.g.:

template <typename T>
class MySystemVisitor : public SystemVisitor {
  ...
}
 
MySystemVisitor<T> visitor;
system.Accept(visitor);

will call the correct Visit overload.

Note

This method does not recurse through the subsystems of a Diagram, but that is easy to do: just call Diagram::GetSystems() in your visitor and then call Accept on the subsystems.
