Example
final Route route = parameterMultiMap(params -> {
final String pString = params.entrySet()
.stream()
.map(e -> e.getKey() + " -> " + e.getValue().size())
.collect(Collectors.joining(", "));
return complete("There are parameters " + pString);
});
// tests:
testRoute(route).run(HttpRequest.GET("/?color=blue&count=42"))
.assertEntity("There are parameters color -> 1, count -> 1");
testRoute(route).run(HttpRequest.GET("/?x=23&x=42"))
.assertEntity("There are parameters x -> 2");
