```
void startNested(RequestPredicate predicate)
```
    Receive notification of the beginning of a nested router function.
    Parameters:
    predicate - the predicate that applies to the nested router functions
    See Also:
    RouterFunctions.nest(RequestPredicate, RouterFunction)
  - endNested
```
void endNested(RequestPredicate predicate)
```
    Receive notification of the end of a nested router function.
    Parameters:
    predicate - the predicate that applies to the nested router functions
    See Also:
    RouterFunctions.nest(RequestPredicate, RouterFunction)
  - route
```
void route(RequestPredicate predicate,
           HandlerFunction<?> handlerFunction)
```
    Receive notification of a standard predicated route to a handler function.
    Parameters:
    predicate - the predicate that applies to the handler function
    handlerFunction - the handler function.
    See Also:
    RouterFunctions.route(RequestPredicate, HandlerFunction)
  - resources
```
void resources(Function<ServerRequest,Optional<Resource>> lookupFunction)
```
    Receive notification of a resource router function.
    Parameters:
    lookupFunction - the lookup function for the resources
    See Also:
    RouterFunctions.resources(Function)
  - unknown
```
void unknown(RouterFunction<?> routerFunction)
```
    Receive notification of an unknown router function. This method is called for router functions that were not created via the various RouterFunctions methods.
    Parameters:
    routerFunction - the router function
