Class StorageGrpc.StorageBlockingStub (2.27.1)

public static final class StorageGrpc.StorageBlockingStub extends AbstractBlockingStub<StorageGrpc.StorageBlockingStub>

A stub to allow clients to do synchronous rpc calls to service Storage.

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).

cancelResumableWrite(CancelResumableWriteRequest request)

public CancelResumableWriteResponse cancelResumableWrite(CancelResumableWriteRequest request)

Cancels an in-progress resumable upload. Any attempts to write to the resumable upload after cancelling the upload will fail. The behavior for currently in progress write operations is not guaranteed - they could either complete before the cancellation or fail if the cancellation completes first.

Returns
Type Description
CancelResumableWriteResponse

queryWriteStatus(QueryWriteStatusRequest request)

public QueryWriteStatusResponse queryWriteStatus(QueryWriteStatusRequest request)

Determines the persisted_size for an object that is being written, which can then be used as the write_offset for the next Write() call. If the object does not exist (i.e., the object has been deleted, or the first Write() has not yet reached the service), this method returns the error NOT_FOUND. The client may call QueryWriteStatus() at any time to determine how much data has been processed for this object. This is useful if the client is buffering data and needs to know which data can be safely evicted. For any sequence of QueryWriteStatus() calls for a given object name, the sequence of returned persisted_size values will be non-decreasing.

Parameter
Name Description
request QueryWriteStatusRequest
Returns
Type Description
QueryWriteStatusResponse
