DownloadDependencies and GetDownloadSize for single group

As I see, group name is not a key. How I could preload all group without adding a tag with group name to all members?

Will be nice to have possibility to preload all keys starting with some string.

Not the most ideal code, but something like this could work to download a group asset bundle.
I didn't test it.

Code (CSharp):

1. public AsyncOperationHandle DownloadGroupAssetBundleAsync(string groupName)
2. {
3.     if (!InitializationOperation.IsDone)
4.         return ResourceManager.CreateChainOperation<IList<IAssetBundleResource>>(InitializationOperation, op => DownloadGroupAssetBundleAsync(groupName).Convert<IList<IAssetBundleResource>>());
5.  
6.     ResourceLocationMap map = m_ResourceLocators.First(locator => locator is ResourceLocationMap) as ResourceLocationMap;
7.  
8.     Dictionary<object, IList<IResourceLocation>> allLocations = map.Locations;
9.  
10.     IEnumerable<IResourceLocation> assetBundlesLocs = allLocations.Values.SelectMany(locations => locations).Where(loc => loc.PrimaryKey.StartsWith(groupName) && loc.ProviderId == typeof(AssetBundleProvider).FullName);
11.     if (!assetBundlesLocs.Any())
12.         return ResourceManager.CreateCompletedOperation<IList<IAssetBundleResource>>(null, new InvalidKeyException(groupName).Message);
13.  
14.     return LoadAssetsAsync<IAssetBundleResource>(assetBundlesLocs, null);
15. }

Probably won't work if you chose Bundle Naming "Only Hash"

 

Yes, this is like I wanted to implement feature if no native logic will be provided. But little bit a lot of coupling to asset bundles.

However that is important functionality and should be in core of Addressables, moreover that is simple to implement:

During catalog composition, add one more catalog entry with key = "group name" and dependencies = "all group entries / bundles".
