What this means is, given we have the following:\n\n``` java\nStorageService storage = ... // Get a storage service (irrelevant how here)\nBucket bucket = storage.get(\"bucket-name\");\nBlob blob = storage.get(\"bucket-name\", \"blobname\");\n```\n\nThe only way to interact with these objects is by keeping a reference to the `StorageService`:\n\n``` java\nBlobReadChannel channel = storage.reader(\"bucket\", \"blob\");\n// or \nBlobReadChannel channel = storage.reader(blob); // I think?\n```\n\nThere's no way to do:\n\n``` java\nBlobReadChannel channel = blob.getReadChannel(); // Or anything like this.\n```\n\nThe purpose of this issue is to discuss whether or not these objects should hold a reference to the `StorageService` which would make things like `blob.getReadChannel()` or `blob.delete()` possible rather than always calling `storage.getReadChannel(blob)` and `storage.delete(blob)`.\n\nThe benefits of this are friendlier-looking code (IMO at least....). The downsides are (I think) serialization becomes a bit more confusing, and what does it mean to send one \"`StorageService`-aware\" `Blob` into another `StorageService` method, ie:\n\n``` java\nStorageService storageA = ... // Authenticated with read permissions only.\nStorageService storageB = ... // Authenticated with read *and* write permissions.\nBlob blobA = storageA.get(\"bucket-name\", \"blob\");\nblobA.delete(); // This should fail: blobA is tied to storageA, which has read-only permissions.\nstorageB.delete(blobA); // Should this \"override\" the `StorageService`?\n```\n\nI have no idea what the right answer is, but wanted to open the floor for discussion.\n\n/cc @aozarov @jboynes \n","author":{"url":"https://github.com/jgeewax","@type":"Person","name":"jgeewax"},"datePublished":"2015-05-12T17:33:01.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":13},"url":"https://github.com/55/google-cloud-java/issues/55"}
