How to get count of globalOnly FacesMessages better?

Question

I write a "not so correct" code to count the globalOnly messages programatically.

for (final FacesMessage message : facesContext.getMessageList()) {
    if (!message.getClass().getCanonicalName().equals("javax.faces.component.MessageFactory.BindingFacesMessage")) {
            globalOnlyMessagesCount++;
    }
}

For non-jsf developres: javax.faces.component.MessageFactory.BindingFacesMessage is a non-visible class, so instanceof doesn't work. As I found the message is a BindingFacesMessage or FacesMessage

Is there any better solution? (except I put the string literal to constant).

Global only messages are identified by a null client ID.

So, this should do, in combination with another getter taking a client ID:

int globalOnlyMessagesCount = facesContext.getMessageList(null).size();
