actionhandler binding impl

[joost]

I was skimming through the source code and noticed the implementation
of bindHandler(a,h);

protected <A extends Action<R>, R extends Result> void
bindHandler( Class<A> actionClass,

Class<? extends ActionHandler<A, R>> handlerClass ) {

bind( ActionHandlerMap.class ).annotatedWith( UniqueAnnotations.create() ).toInstance(
new ActionHandlerMapImpl<A, R>( actionClass,
handlerClass ) );
}

I was wondering why the : 'annotatedWith(UniqueAnnotations.create())'
is used ?
Is that to prevent accidental injection ?
It looks like it would work without this annotatedWith also, or am I
missing something here?

thanks Joost

I figured it out,
I guess it is just for having unique bindings that this random
annotation was added

Hmm, yeah, probably. There was a good reason for it back in the day. I think it was to guarantee that each binding would be unique and all the ActionHandlerMap instances would be loaded. But I'm a bit rusty on this stuff…
