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).

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: 


 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 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().

When this API is used to delete an object from a bucket that has soft delete policy enabled, the object becomes soft deleted, and the `softDeleteTime` and `hardDeleteTime` properties are set on the object. This API cannot be used to permanently delete soft-deleted objects. Soft-deleted objects are permanently deleted according to their `hardDeleteTime`.

You can use the [`RestoreObject`][google.storage.v2.Storage.RestoreObject] API to restore soft-deleted objects until the soft delete retention period has passed.

Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.

  • readObjectCallable()

BidiReadObject

Reads an object's data.

This is a bi-directional API with the added support for reading multiple ranges within one stream both within and across multiple messages. If the server encountered an error for any of the inputs, the stream will be closed with the relevant error code. Because the API allows for multiple outstanding requests, when the stream is closed the error response will contain a BidiReadObjectRangesError proto in the error extension describing the error for each outstanding read_id.

**IAM Permissions**:

Requires `storage.objects.get`

[IAM permission](https://cloud.google.com/iam/docs/overview#permissions) on the bucket.

  • updateObjectCallable()

WriteObject

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()`, populating a `WriteObjectSpec` into that request. They should then attach the returned `upload_id` to the first message of each following call to `WriteObject`. If the stream is closed before finishing the upload (either explicitly by the client or due to a network error or an error response from the server), the client should do as follows: - Check the result Status of the stream, to determine if writing can be resumed on this stream or must be restarted from scratch (by calling `StartResumableWrite()`). The resumable errors are DEADLINE_EXCEEDED, INTERNAL, and UNAVAILABLE. For each case, the client should use binary exponential backoff before retrying. Additionally, writes can be resumed after RESOURCE_EXHAUSTED errors, but only after taking appropriate measures, which may include reducing aggregate send rate across clients and/or requesting a quota increase for your project. - If the call to `WriteObject` returns `ABORTED`, that indicates concurrent attempts to update the resumable write, caused either by multiple racing clients or by a single client where the previous request was timed out on the client side but nonetheless reached the server. In this case the client should take steps to prevent further concurrent writes (e.g., increase the timeouts, stop using more than one process to perform the upload, etc.), and then should follow the steps below for resuming the upload. - For resumable errors, the client should call `QueryWriteStatus()` and then continue writing from the returned `persisted_size`. This may be less than the amount of data the client previously sent. Note also that it is acceptable to send data starting at an offset earlier than the returned `persisted_size`; in this case, the service will skip data at offsets that were already persisted (without checking that it matches the previously written data), and write only the data starting from the persisted offset. Even though the data isn't written, it may still incur a performance cost over resuming at the correct write offset. This behavior can make client-side handling simpler in some cases. - Clients must only send data that is a multiple of 256 KiB per message, unless the object is being finished with `finish_write` set to `true`.

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.

Attempting to resume an already finalized object will result in an OK status, with a `WriteObjectResponse` containing the finalized object's metadata.

Alternatively, the BidiWriteObject operation may be used to write an object with controls over flushing and the ability to fetch the ability to determine the current persisted size.

**IAM Permissions**:

Requires `storage.objects.create` [IAM permission](https://cloud.google.com/iam/docs/overview#permissions) on the bucket.

Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.

  • writeObjectCallable()

BidiWriteObject

Stores a new object and metadata.

This is similar to the WriteObject call with the added support for manual flushing of persisted state, and the ability to determine current persisted size without closing the stream.

The client may specify one or both of the `state_lookup` and `flush` fields in each BidiWriteObjectRequest. If `flush` is specified, the data written so far will be persisted to storage. If `state_lookup` is specified, the service will respond with a BidiWriteObjectResponse that contains the persisted size. If both `flush` and `state_lookup` are specified, the flush will always occur before a `state_lookup`, so that both may be set in the same request and the returned state will be the state of the object post-flush. When the stream is closed, a BidiWriteObjectResponse will always be sent to the client, regardless of the value of `state_lookup`.

Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.

  • bidiWriteObjectCallable()

ListObjects

Retrieves a list of objects matching the criteria.

**IAM Permissions**:

The authenticated user requires `storage.objects.list` [IAM permission](https://cloud.google.com/iam/docs/overview#permissions) to use this method. To return object ACLs, the authenticated user must also have the `storage.objects.getIamPolicy` permission.

Request object method variants only take one parameter, a request object, which must be constructed before the call.

  • listObjects(ListObjectsRequest request)

"Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method.

  • listObjects(BucketName parent)

  • listObjects(String parent)

Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.

  • listObjectsPagedCallable()

  • listObjectsCallable()

RewriteObject

Rewrites a source object to a destination object. Optionally overrides metadata.

  • rewriteObject(RewriteObjectRequest request)

Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.

  • rewriteObjectCallable()

StartResumableWrite

Starts a resumable write operation. This method is part of the [Resumable upload](https://cloud.google.com/storage/docs/resumable-uploads) feature. This allows you to upload large objects in multiple chunks, which is more resilient to network interruptions than a single upload. The validity duration of the write operation, and the consequences of it becoming invalid, are service-dependent.

**IAM Permissions**:

Requires `storage.objects.create` [IAM permission](https://cloud.google.com/iam/docs/overview#permissions) on the bucket.

Request object method variants only take one parameter, a request object, which must be constructed before the call.

  • startResumableWrite(StartResumableWriteRequest request)

Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.

  • startResumableWriteCallable()

QueryWriteStatus

Determines the `persisted_size` of an object that is being written. This method is part of the [resumable upload](https://cloud.google.com/storage/docs/resumable-uploads) feature. The returned value is the size of the object that has been persisted so far. The value can be used as the `write_offset` for the next `Write()` call.

If the object does not exist, meaning if it was deleted, or the first `Write()` has not yet reached the service, this method returns the error `NOT_FOUND`.

This method is useful for clients that buffer data and need to know which data can be safely evicted. The client can call `QueryWriteStatus()` at any time to determine how much data has been logged for this object. For any sequence of `QueryWriteStatus()` calls for a given object name, the sequence of returned `persisted_size` values are non-decreasing.

Request object method variants only take one parameter, a request object, which must be constructed before the call.

  • queryWriteStatus(QueryWriteStatusRequest request)

  • moveObject(BucketName bucket, String sourceObject, String destinationObject)

  • moveObject(String bucket, String sourceObject, String destinationObject)

Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.

  • moveObjectCallable()

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: 


 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 StorageSettings storageSettings =
     StorageSettings.newBuilder()
         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
         .build();
 StorageClient storageClient = StorageClient.create(storageSettings);

To customize the endpoint: 


 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 StorageSettings storageSettings = StorageSettings.newBuilder().setEndpoint(myEndpoint).build();
 StorageClient storageClient = StorageClient.create(storageSettings);

    • deleteObject

      public final void deleteObject(BucketName bucket, String object)
      Deletes an object and its metadata. Deletions are permanent if versioning is not enabled for the bucket, or if the generation parameter is used, or if [soft delete](https://cloud.google.com/storage/docs/soft-delete) is not enabled for the bucket. When this API is used to delete an object from a bucket that has soft delete policy enabled, the object becomes soft deleted, and the `softDeleteTime` and `hardDeleteTime` properties are set on the object. This API cannot be used to permanently delete soft-deleted objects. Soft-deleted objects are permanently deleted according to their `hardDeleteTime`.

      You can use the [`RestoreObject`][google.storage.v2.Storage.RestoreObject] API to restore soft-deleted objects until the soft delete retention period has passed.

      **IAM Permissions**:

      Requires `storage.objects.delete` [IAM permission](https://cloud.google.com/iam/docs/overview#permissions) on the bucket.

    • deleteObjectCallable

      public final com.google.api.gax.rpc.UnaryCallable<DeleteObjectRequest,com.google.protobuf.Empty> deleteObjectCallable()
      Deletes an object and its metadata. Deletions are permanent if versioning is not enabled for the bucket, or if the generation parameter is used, or if [soft delete](https://cloud.google.com/storage/docs/soft-delete) is not enabled for the bucket. When this API is used to delete an object from a bucket that has soft delete policy enabled, the object becomes soft deleted, and the `softDeleteTime` and `hardDeleteTime` properties are set on the object. This API cannot be used to permanently delete soft-deleted objects. Soft-deleted objects are permanently deleted according to their `hardDeleteTime`.

      You can use the [`RestoreObject`][google.storage.v2.Storage.RestoreObject] API to restore soft-deleted objects until the soft delete retention period has passed.

      **IAM Permissions**:

      Requires `storage.objects.delete` [IAM permission](https://cloud.google.com/iam/docs/overview#permissions) on the bucket.

      Reads an object's data.

      This is a bi-directional API with the added support for reading multiple ranges within one stream both within and across multiple messages. If the server encountered an error for any of the inputs, the stream will be closed with the relevant error code. Because the API allows for multiple outstanding requests, when the stream is closed the error response will contain a BidiReadObjectRangesError proto in the error extension describing the error for each outstanding read_id.

      updateMask - Required. List of fields to be updated.

      To specify ALL fields, equivalent to the JSON API's "update" function, specify a single field with the value `*`. Note: not recommended. If a new field is introduced at a later time, an older client updating with the `*` may accidentally reset the new field's value.

      Not specifying any fields is an error.

      Throws:
      com.google.api.gax.rpc.ApiException - if the remote call fails

    • writeObjectCallable

      public final com.google.api.gax.rpc.ClientStreamingCallable<WriteObjectRequest,WriteObjectResponse> writeObjectCallable()
      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()`, populating a `WriteObjectSpec` into that request. They should then attach the returned `upload_id` to the first message of each following call to `WriteObject`. If the stream is closed before finishing the upload (either explicitly by the client or due to a network error or an error response from the server), the client should do as follows: - Check the result Status of the stream, to determine if writing can be resumed on this stream or must be restarted from scratch (by calling `StartResumableWrite()`). The resumable errors are DEADLINE_EXCEEDED, INTERNAL, and UNAVAILABLE. For each case, the client should use binary exponential backoff before retrying. Additionally, writes can be resumed after RESOURCE_EXHAUSTED errors, but only after taking appropriate measures, which may include reducing aggregate send rate across clients and/or requesting a quota increase for your project. - If the call to `WriteObject` returns `ABORTED`, that indicates concurrent attempts to update the resumable write, caused either by multiple racing clients or by a single client where the previous request was timed out on the client side but nonetheless reached the server. In this case the client should take steps to prevent further concurrent writes (e.g., increase the timeouts, stop using more than one process to perform the upload, etc.), and then should follow the steps below for resuming the upload. - For resumable errors, the client should call `QueryWriteStatus()` and then continue writing from the returned `persisted_size`. This may be less than the amount of data the client previously sent. Note also that it is acceptable to send data starting at an offset earlier than the returned `persisted_size`; in this case, the service will skip data at offsets that were already persisted (without checking that it matches the previously written data), and write only the data starting from the persisted offset. Even though the data isn't written, it may still incur a performance cost over resuming at the correct write offset. This behavior can make client-side handling simpler in some cases. - Clients must only send data that is a multiple of 256 KiB per message, unless the object is being finished with `finish_write` set to `true`.

      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.

      Attempting to resume an already finalized object will result in an OK status, with a `WriteObjectResponse` containing the finalized object's metadata.

      Alternatively, the BidiWriteObject operation may be used to write an object with controls over flushing and the ability to fetch the ability to determine the current persisted size.

      **IAM Permissions**:

      Requires `storage.objects.create` [IAM permission](https://cloud.google.com/iam/docs/overview#permissions) on the bucket.

 try (StorageClient storageClient = StorageClient.create()) {
   ApiStreamObserver<WriteObjectRequest> responseObserver =
       new ApiStreamObserver<WriteObjectRequest>() {
         {@literal @}Override
         public void onNext(WriteObjectResponse response) {
           // Do something when a response is received.

         public void onCompleted() {
           // Do something when complete.

    • bidiWriteObjectCallable

      public final com.google.api.gax.rpc.BidiStreamingCallable<BidiWriteObjectRequest,BidiWriteObjectResponse> bidiWriteObjectCallable()
      Stores a new object and metadata.

      This is similar to the WriteObject call with the added support for manual flushing of persisted state, and the ability to determine current persisted size without closing the stream.

      The client may specify one or both of the `state_lookup` and `flush` fields in each BidiWriteObjectRequest. If `flush` is specified, the data written so far will be persisted to storage. If `state_lookup` is specified, the service will respond with a BidiWriteObjectResponse that contains the persisted size. If both `flush` and `state_lookup` are specified, the flush will always occur before a `state_lookup`, so that both may be set in the same request and the returned state will be the state of the object post-flush. When the stream is closed, a BidiWriteObjectResponse will always be sent to the client, regardless of the value of `state_lookup`.

 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in

           .setFlush(true)
           .setFinishWrite(true)

           .build();

    • startResumableWrite

      public final StartResumableWriteResponse startResumableWrite(StartResumableWriteRequest request)
      Starts a resumable write operation. This method is part of the [Resumable upload](https://cloud.google.com/storage/docs/resumable-uploads) feature. This allows you to upload large objects in multiple chunks, which is more resilient to network interruptions than a single upload. The validity duration of the write operation, and the consequences of it becoming invalid, are service-dependent.

      **IAM Permissions**:

      Requires `storage.objects.create` [IAM permission](https://cloud.google.com/iam/docs/overview#permissions) on the bucket.

      Sample code: 

      
 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 try (StorageClient storageClient = StorageClient.create()) {

           .setObjectChecksums(ObjectChecksums.newBuilder().build())
           .build();
   StartResumableWriteResponse response = storageClient.startResumableWrite(request);
 }
      Parameters:
      request - The request object containing all of the parameters for the API call.
      Throws:
      com.google.api.gax.rpc.ApiException - if the remote call fails

    • startResumableWriteCallable

      public final com.google.api.gax.rpc.UnaryCallable<StartResumableWriteRequest,StartResumableWriteResponse> startResumableWriteCallable()
      Starts a resumable write operation. This method is part of the [Resumable upload](https://cloud.google.com/storage/docs/resumable-uploads) feature.

    • queryWriteStatus

      public final QueryWriteStatusResponse queryWriteStatus(String uploadId)
      Determines the `persisted_size` of an object that is being written. This method is part of the [resumable upload](https://cloud.google.com/storage/docs/resumable-uploads) feature. The returned value is the size of the object that has been persisted so far. The value can be used as the `write_offset` for the next `Write()` call.

      If the object does not exist, meaning if it was deleted, or the first `Write()` has not yet reached the service, this method returns the error `NOT_FOUND`.

      This method is useful for clients that buffer data and need to know which data can be safely evicted. The client can call `QueryWriteStatus()` at any time to determine how much data has been logged for this object. For any sequence of `QueryWriteStatus()` calls for a given object name, the sequence of returned `persisted_size` values are non-decreasing.

      Sample code: 

      
 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.

 try (StorageClient storageClient = StorageClient.create()) {
   String uploadId = "uploadId1563990780";

 }
      Parameters:
      uploadId - Required. The name of the resume token for the object whose write status is being requested.
      Throws:
      com.google.api.gax.rpc.ApiException - if the remote call fails
