- * Service Description: Manages Google Cloud Storage resources.
+ * Service Description: ## API Overview and Naming Syntax
+ *
+ * <p>The Cloud Storage gRPC API allows applications to read and write data through the abstractions
+ * of buckets and objects. For a description of these abstractions please see
+ * https://cloud.google.com/storage/docs.
+ *
+ * <p>Resources are named as follows: - Projects are referred to as they are defined by the Resource
+ * Manager API, using strings like `projects/123456` or `projects/my-string-id`. - Buckets are named
+ * using string names of the form: `projects/{project}/buckets/{bucket}` For globally unique
+ * buckets, `_` may be substituted for the project. - Objects are uniquely identified by their name
+ * along with the name of the bucket they belong to, as separate strings in this API. For example:
+ *
+ * <p>ReadObjectRequest { bucket: 'projects/_/buckets/my-bucket' object: 'my-object' } Note that
+ * object names can contain `/` characters, which are treated as any other character (no special
+ * directory semantics).
  *
  * <p>This class provides the ability to make remote calls to the backing service through method
  * calls that map to API methods. Sample code to get started:
  *
  * <pre>{@code
  * try (StorageClient storageClient = StorageClient.create()) {
- *   StartResumableWriteRequest request =
- *       StartResumableWriteRequest.newBuilder()
- *           .setWriteObjectSpec(WriteObjectSpec.newBuilder().build())
- *           .setCommonObjectRequestParams(CommonObjectRequestParams.newBuilder().build())
- *           .setCommonRequestParams(CommonRequestParams.newBuilder().build())
- *           .build();
- *   StartResumableWriteResponse response = storageClient.startResumableWrite(request);
+ *   BucketName name = BucketName.of("[PROJECT]", "[BUCKET]");
+ *   storageClient.deleteBucket(name);
  * }
  * }</pre>

-   * Stores a new object and metadata.
-   *
-   * <p>An object can be written either in a single message stream or in a resumable sequence of
-   * message streams. To write using a single stream, the client should include in the first message
-   * of the stream an `WriteObjectSpec` describing the destination bucket, object, and any
-   * preconditions. Additionally, the final message must set 'finish_write' to true, or else it is
-   * an error.
-   *
-   * <p>For a resumable write, the client should instead call `StartResumableWrite()` and provide
-   * that method an `WriteObjectSpec.` They should then attach the returned `upload_id` to the first
-   * message of each following call to `Create`. If there is an error or the connection is broken
-   * during the resumable `Create()`, the client should check the status of the `Create()` by
-   * calling `QueryWriteStatus()` and continue writing from the returned `committed_size`. This may
-   * be less than the amount of data the client previously sent.
-   *
-   * <p>The service will not view the object as complete until the client has sent a
-   * `WriteObjectRequest` with `finish_write` set to `true`. Sending any requests on a stream after
-   * sending a request with `finish_write` set to `true` will cause an error. The client
-   * &#42;&#42;should&#42;&#42; check the response it receives to determine how much data the
-   * service was able to commit and whether the service views the object as complete.

+   * Stores a new object and metadata.
+   *
+   * <p>An object can be written either in a single message stream or in a resumable sequence of
+   * message streams. To write using a single stream, the client should include in the first message
+   * of the stream an `WriteObjectSpec` describing the destination bucket, object, and any
+   * preconditions. Additionally, the final message must set 'finish_write' to true, or else it is
+   * an error.
+   *
+   * <p>For a resumable write, the client should instead call `StartResumableWrite()` and provide
+   * that method an `WriteObjectSpec.` They should then attach the returned `upload_id` to the first
+   * message of each following call to `Create`. If there is an error or the connection is broken
+   * during the resumable `Create()`, the client should check the status of the `Create()` by
+   * calling `QueryWriteStatus()` and continue writing from the returned `persisted_size`. This may
+   * be less than the amount of data the client previously sent.
+   *
+   * <p>The service will not view the object as complete until the client has sent a
+   * `WriteObjectRequest` with `finish_write` set to `true`. Sending any requests on a stream after
+   * sending a request with `finish_write` set to `true` will cause an error. The client
+   * &#42;&#42;should&#42;&#42; check the response it receives to determine how much data the

  * <p>======================= StorageClient =======================
  *
- * <p>Service Description: Manages Google Cloud Storage resources.
+ * <p>Service Description: ## API Overview and Naming Syntax
+ *
+ * <p>The Cloud Storage gRPC API allows applications to read and write data through the abstractions
+ * of buckets and objects. For a description of these abstractions please see
+ * https://cloud.google.com/storage/docs.
+ *
+ * <p>Resources are named as follows: - Projects are referred to as they are defined by the Resource
+ * Manager API, using strings like `projects/123456` or `projects/my-string-id`. - Buckets are named
+ * using string names of the form: `projects/{project}/buckets/{bucket}` For globally unique
+ * buckets, `_` may be substituted for the project. - Objects are uniquely identified by their name
+ * along with the name of the bucket they belong to, as separate strings in this API. For example:
+ *
+ * <p>ReadObjectRequest { bucket: 'projects/_/buckets/my-bucket' object: 'my-object' } Note that
+ * object names can contain `/` characters, which are treated as any other character (no special
+ * directory semantics).
  *
  * <p>Sample for StorageClient:
  *
  * <pre>{@code
  * try (StorageClient storageClient = StorageClient.create()) {
- *   StartResumableWriteRequest request =
- *       StartResumableWriteRequest.newBuilder()
- *           .setWriteObjectSpec(WriteObjectSpec.newBuilder().build())
- *           .setCommonObjectRequestParams(CommonObjectRequestParams.newBuilder().build())
- *           .setCommonRequestParams(CommonRequestParams.newBuilder().build())
- *           .build();
- *   StartResumableWriteResponse response = storageClient.startResumableWrite(request);
+ *   BucketName name = BucketName.of("[PROJECT]", "[BUCKET]");
+ *   storageClient.deleteBucket(name);
  * }
  * }</pre>
