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. - * - *

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: - * - *

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). - * - *

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: - * - * 

{@code
- * try (StorageClient storageClient = StorageClient.create()) {
- *   BucketName name = BucketName.of("[PROJECT]", "[BUCKET]");
- *   storageClient.deleteBucket(name);
- * }

Note: close() needs to be called on the StorageClient object to clean up resources such as - * threads. In the example above, try-with-resources is used, which automatically calls close(). - * - *

The surface of this class includes several types of Java methods for each of the API's - * methods: - * - *

    - *
  1. A "flattened" method. With this type of method, the fields of the request type have been - * converted into function parameters. It may be the case that not all fields are available as - * parameters, and not every API method will have a flattened method entry point. - *
  2. A "request object" method. This type of method only takes one parameter, a request object, - * which must be constructed before the call. Not every API method will have a request object - * method. - *
  3. A "callable" method. This type of method takes no parameters and returns an immutable API - * callable object, which can be used to initiate calls to the service. - *
- * - *

See the individual methods for example code. - * - *

Many parameters require resource names to be formatted in a particular way. To assist with - * these names, this class includes a format method for each type of name, and additionally a parse - * method to extract the individual identifiers contained within names that are returned. - * - *

This class can be customized by passing in a custom instance of StorageSettings to create(). - * For example: - * - *

To customize credentials: - * - * 

{@code
- * StorageSettings storageSettings =
- *     StorageSettings.newBuilder()
- *         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
- *         .build();
- * StorageClient storageClient = StorageClient.create(storageSettings);
- * }
- * - *

To customize the endpoint: - * - * 

{@code
- * StorageSettings storageSettings = StorageSettings.newBuilder().setEndpoint(myEndpoint).build();
- * StorageClient storageClient = StorageClient.create(storageSettings);
- * }
- * - *

-   * Stores a new object and metadata.
-   *
-   * 
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.
-   *
-   * 
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.
-   *
-   * 
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
-   * **should** 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.
-   *
-   * 
Sample code:
-   *
-   * 
{@code
-   * try (StorageClient storageClient = StorageClient.create()) {
-   *   ApiStreamObserver responseObserver =
-   *       new ApiStreamObserver() {

-// AUTO-GENERATED DOCUMENTATION AND CLASS.
-/**
- * Settings class to configure an instance of {@link StorageClient}.
- *
- * 
The default instance has everything set to sensible defaults:
- *
- * 
    
- *   
  • The default service address (storage.googleapis.com) and default port (443) are used.
- *   
  • Credentials are acquired automatically through Application Default Credentials.
- *   
  • Retries are configured for idempotent methods but not for non-idempotent methods.
- * 

- *
- * 
The builder of this class is recursive, so contained classes are themselves builders. When
- * build() is called, the tree of builders is called to create the complete settings object.
- *
- * 
For example, to set the total timeout of deleteBucket to 30 seconds:
- *
- * 
{@code
- * StorageSettings.Builder storageSettingsBuilder = StorageSettings.newBuilder();
- * storageSettingsBuilder
- *     .deleteBucketSettings()
- *     .setRetrySettings(
- *         storageSettingsBuilder
- *             .deleteBucketSettings()
- *             .getRetrySettings()
- *             .toBuilder()
- *             .setTotalTimeout(Duration.ofSeconds(30))
- *             .build());
- * StorageSettings storageSettings = storageSettingsBuilder.build();
- * }

======================= StorageClient =======================
- *
- * 
Service Description: ## API Overview and Naming Syntax
- *
- * 
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.
- *
- * 
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:
- *
- * 
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).
- *
- * 
Sample for StorageClient:
- *
- * 
{@code
- * try (StorageClient storageClient = StorageClient.create()) {
- *   BucketName name = BucketName.of("[PROJECT]", "[BUCKET]");
- *   storageClient.deleteBucket(name);
- * }
- * }

-// AUTO-GENERATED DOCUMENTATION AND CLASS.
-/**
- * Settings class to configure an instance of {@link StorageStub}.
- *
- * 
The default instance has everything set to sensible defaults:
- *
- * 
    
- *   
  • The default service address (storage.googleapis.com) and default port (443) are used.
- *   
  • Credentials are acquired automatically through Application Default Credentials.
- *   
  • Retries are configured for idempotent methods but not for non-idempotent methods.
- * 

- *
- * 
The builder of this class is recursive, so contained classes are themselves builders. When
- * build() is called, the tree of builders is called to create the complete settings object.
- *
- * 
For example, to set the total timeout of deleteBucket to 30 seconds:
- *
- * 
{@code
- * StorageStubSettings.Builder storageSettingsBuilder = StorageStubSettings.newBuilder();
- * storageSettingsBuilder
- *     .deleteBucketSettings()
- *     .setRetrySettings(
- *         storageSettingsBuilder
- *             .deleteBucketSettings()
- *             .getRetrySettings()
- *             .toBuilder()
- *             .setTotalTimeout(Duration.ofSeconds(30))
- *             .build());
- * StorageStubSettings storageSettings = storageSettingsBuilder.build();
- * }

-# Conformance Testing
-
-This library leverages the conformance tests defined in [googleapis/conformance-tests](https://github.com/googleapis/conformance-tests)
-to ensure adherence to expected behaviors.
-
-Access to the conformance tests is achieved via dependencies on 
-[`com.google.cloud:google-cloud-conformance-tests`](https://github.com/googleapis/java-conformance-tests)
-which contains all generated protos and associated files necessary for loading
-and accessing the tests.
-
-## Running the Conformance Tests
-
-Conformance tests are written and run as part of the JUnit tests suite.
-
-## Suites
-
-### Automatic Retries
-
-The JUnit tests class is [`ITRetryConformanceTest.java`](./src/test/java/com/google/cloud/storage/conformance/retry/ITRetryConformanceTest.java)
-and is considered part of the integration test suite.
-
-This tests suite ensures that automatic retries for operations are properly defined
-and handled to ensure data integrity.
-
-#### Prerequisites
-1. Java 8+
-2. Maven
-3. Docker (Docker for MacOS has been tested and verified to work as well)
-
-#### Test Suite Overview
-
-The test suite uses the [storage-testbench](https://github.com/googleapis/storage-testbench)
-to configure and generate tests cases which use fault injection to ensure conformance.
-
-`ITRetryConformanceTest` encapsulates all the necessary lifecycle points needed
-to run the test suite, including:
-1. Running the testbench server via docker
-2. Setup, validation, cleanup of individual test cases with the testbench
-3. CI Graceful enforcement of test failures (enforce no regressions, but allow 
-   for some cases to not pass without failing the whole run)
-
-A sequence diagram of how the tests are loaded run, and interact with testbench
-can be seen below. Time moves from top to bottom, while component interactions
-are shown via arrows laterally.

-/**
- *
- *
- * 
- * ## API Overview and Naming Syntax
- * 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.
- * 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:
- *       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).
- *

-   * ## API Overview and Naming Syntax
-   * 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.
-   * 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:
-   *       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).

-  /**
-   *
-   *
-   * 
-   * ## API Overview and Naming Syntax
-   * 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.
-   * 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:
-   *       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).
-   *

-   * the abstractions of buckets and objects. For a description of these
-   * abstractions please see https://cloud.google.com/storage/docs.
-   * 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:
-   *       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).

-   * ## API Overview and Naming Syntax
-   * 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.
-   * 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:
-   *       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).
-   *

-// ## API Overview and Naming Syntax
-//
-// 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.
-//
-// 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:
-//
-//       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).

-# Storage Sample Application with Native Image
-
-The Storage sample application demonstrates some common operations with Google Cloud Storage and is compatible with Native Image compilation.
-
-## Setup Instructions
-
-You will need to follow these prerequisite steps in order to run these samples:
-
-1. If you have not already, [create a Google Cloud Platform Project](https://cloud.google.com/resource-manager/docs/creating-managing-projects#creating_a_project).
-
-2. Install the [Google Cloud SDK](https://cloud.google.com/sdk/) which will allow you to run the sample with your project's credentials.
-
-   Once installed, log in with Application Default Credentials using the following command:
-
-    ```
-    gcloud auth application-default login
-    ```
-
-   **Note:** Authenticating with Application Default Credentials is convenient to use during development, but we recommend [alternate methods of authentication](https://cloud.google.com/docs/authentication/production) during production use.
-
-3. Install the GraalVM compiler.
-
-   You can follow the [official installation instructions](https://www.graalvm.org/docs/getting-started/#install-graalvm) from the GraalVM website.
-   After following the instructions, ensure that you install the Native Image extension installed by running:
-
-    ```
-    gu install native-image
-    ```
-
-   Once you finish following the instructions, verify that the default version of Java is set to the GraalVM version by running `java -version` in a terminal.
-
-   You will see something similar to the below output:
-
-    ```
-    $ java -version
-   
-    openjdk version "11.0.7" 2020-04-14
-    OpenJDK Runtime Environment GraalVM CE 20.1.0 (build 11.0.7+10-jvmci-20.1-b02)
-    OpenJDK 64-Bit Server VM GraalVM CE 20.1.0 (build 11.0.7+10-jvmci-20.1-b02, mixed mode, sharing)
-    ```
-
-4. [Enable the Cloud Storage APIs](https://console.cloud.google.com/apis/api/storage.googleapis.com).
-
-### Run with Native Image Compilation
-
-Navigate to this directory in a new terminal.
-
-1. Compile the application using the Native Image Compiler. This step may take a few minutes.
-
-    ```
-    mvn package -P native -DskipTests
-    ```
-
-2. Run the application:
-
-    ```
-    ./target/native-image-sample
-    ```
-
-3. The application will run through basic Cloud Storage operations of creating, reading, and deleting Cloud Storage resources.
-
-   You can manually manage Cloud Storage resources through [Google Cloud Console](https://console.cloud.google.com/storage) to verify that the resources are cleaned up.
-
-    ```
-    Creating bucket nativeimage-sample-bucket-7221f161-688c-4a7a-9120-8900d20f0802
-    Write file to bucket.
-    Reading the file that was written...
-    Successfully wrote to file: Hello World!
-    Cleaning up resources...
-    Deleted file nativeimage-sample-file-5d927aaf-cb03-41de-8383-696733893db5
-    Deleted bucket nativeimage-sample-bucket-7221f161-688c-4a7a-9120-8900d20f0802
-   ```
-   
-## Sample Integration test with Native Image Support
-
-In order to run the sample integration test as a native image, call the following command:
-
-   ```
-   mvn test -Pnative
-   ```
