MqttWildcard

[LennartHennigs]

Hey Simon, I find your implementation really really helpful. The callbacks for subscribe and publish was exactly I was looking for. So thanks a lot for this.

I have a small question though. Could you provide an example for the MqttWildcard class you also have in here? Thanks

It's used here in the other .cpp File.

Just compare two Strings where one of them contains a wildcard like foo/+/bar and the other one the topic that you want to match like foo/something/bar:

if (MqttWildcard::wildcardMatch(topic_string, wildcard_string)) {
    // topic matches the wildcard
}
