Getting IResourceLocations from an IResourceLocator?

I'm trying to come up with some method of simply cataloging what addressables are available at runtime. One way to do this would be if there's a way to simply get the list of IResourceLocation objects that an IResourceLocator knows about, but that doesn't seem to be possible without doing some nasty gymnastics about looking through all the keys and building a list. Is there some way I'm missing to do this, or some reason it isn't a good idea?

Another option that would work for my case but is less general would be if resourceLocator.Locate(null, Type, out locations)) would give all the locations for the specified Type, but that throws an exception.

 

(locator as ResourceLocationMap).Locations

seems what you're asking for? The key is an address, and the value is

IList<IResourceLocation>

. You can just get all values and flatten into a list, or iterate using generator (yield return).

 

Thanks for the reply. That's a good idea, but ResourceLocationMap is just one implementation of IResourceLocator, so there's no guarantee that the Addressables.ResourceLocators list will actually allow that cast in the general case.

It might work in practice to just test the class and put in a case for each implementation that actually exists in the package but that would always be kind of a hack (still better than nothing though...)

 

Currently only two classes implemented

IResourceLocator

,

ResourceLocationMap 

for the addressable managed assets, and

LegacyResourcesLocator

for the assets loaded from resources directories. The later is half-baked without the ability to get all keys. So I guess the approach just works in practice. And of course you can raise exception for other cases.
