Java: Count Anonymous Class for "classes" metric

[mylinhdao]

In Java, you can define Anonymous Class. They are classes with no name, but with implementation. The HelloWorld frenchGreeting in this example from java doc is an Anomymous Class:

interface HelloWorld {
    public void greetSomeone(String someone);
}
HelloWorld frenchGreeting = new HelloWorld() {
    String name = "tout le monde";
    public void greetSomeone(String someone) {
        name = someone;
        System.out.println("Salut " + name);
    }
};

We should count anonymous class for "classes" metric.
