{"@context":"https://schema.org","@type":"DiscussionForumPosting","headline":"Operations on Buckets should use Storage.*Option types","articleBody":"Some of the static classes in `Storage`, such as `BlobTargetOption` which is used by `Storage.create()`, are also being erroneously used in `Bucket`. This is problematic because `Bucket` keys of of path `Strings`, not `BlobInfo` instances, and therefore isn't able to extract information like the blob's generation, causing a line like this:\n\n```\nbucket.create(file, data, null, BlobTargetOption.generationMatch());\n```\n\nto fail:\n\n```\n java.lang.IllegalArgumentException: Option ifGenerationMatch is missing a value\n     at com.google.common.base.Preconditions.checkArgument(Preconditions.java:122)\n     at com.google.gcloud.storage.StorageImpl.addToOptionMap(StorageImpl.java:651)\n     at com.google.gcloud.storage.StorageImpl.addToOptionMap(StorageImpl.java:643)\n     at com.google.gcloud.storage.StorageImpl.optionMap(StorageImpl.java:681)\n     at com.google.gcloud.storage.StorageImpl.optionMap(StorageImpl.java:660)\n     at com.google.gcloud.storage.StorageImpl.optionMap(StorageImpl.java:695)\n     at com.google.gcloud.storage.StorageImpl.optionMap(StorageImpl.java:703)\n     at com.google.gcloud.storage.StorageImpl.create(StorageImpl.java:140)\n     at com.google.gcloud.storage.StorageImpl.create(StorageImpl.java:129)\n     at com.google.gcloud.storage.Bucket.create(Bucket.java:360)\n```\n\nAnd there is no way in `Storage.BlobTargetOption` to actually specify a generation.\n\nI don't think `Bucket` should have any dependency on the `Storage.*Option` types. There's clearly a good amount of overlap, but I don't think that's a good enough reason for them to share these types. Even where they behave the same it's confusing for the caller.\n\nThey could extend from a shared parent if we wanted, but that should be an implementation detail.\n\nI can put together a patch to remove the dependencies on `Storage.*Option` from `Bucket` if that's desired.\n","author":{"url":"https://github.com/dimo414","@type":"Person","name":"dimo414"},"datePublished":"2016-03-02T06:19:18.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":3},"url":"https://github.com/702/google-cloud-java/issues/702"}
