What design pattern is this?

Question

I know that everything we do in programming can be described as a design template (even an abstract method has a design template called a template method)

public class Guicer extends AbstractModule {
    private static Injector injector = Guice.createInjector(new Guicer());

    public static void setInjector(Injector injector) {
        Guicer.injector = injector;
    }

    public static <T> T getInstance(Class<T> c) {
        return injector.getInstance(c);
    }

    @Override
    protected void configure() {

    }
}

What design patterns are used in this code? I'd like to call this class GuiceStateHolder, but I'm not sure about that.

Answer 1

Well, I would call this bit:

private static Injector injector = Guice.createInjector(new Guicer());

public static void setInjector(Injector injector) {
    Guicer.injector = injector;
}

global variable with record.

And here:

public static <T> T getInstance(Class<T> c) {
    return injector.getInstance(c);
}

Answer 2

, , , (, Guice) factory (getInstance()).

Answer 3

This snippet is not a catalog design template. Templates (with the exception of Singleton) typically present more complex relationships than setting a default mutable implementation.
