    ToIntFunction<Endpoint> function = endpoint -> { if (endpoint.equals(Endpoint.of("foo.com"))) { return 5; } if (endpoint.host().contains("bar.com")) { return Integer.MAX_VALUE; // The value will be clamped at the number of event loops. } return -1; // Should return 0 or a negative value to use the default value. }
