Method Details

startNested

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

• 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

• 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.

resources

void resources(Function<ServerRequest,Optional<Resource>> lookupFunction)

Receive notification of a resource router function.

Parameters:

lookupFunction - the lookup function for the resources
