Class SnapshotsClient (2.29.0-rc)

Service for the snapshots resource.

https://cloud.google.com/compute/docs/reference/rest/v1/snapshots

Equality

Instances of this class created via copy-construction or copy-assignment always compare equal. Instances created with equal std::shared_ptr<*Connection> objects compare equal. Objects that compare equal share the same underlying resources.

Performance

Creating a new instance of this class is a relatively expensive operation, new objects establish new connections to the service. In contrast, copy-construction, move-construction, and the corresponding assignment operations are relatively efficient as the copies share all underlying resources.

Thread Safety

Concurrent access to different instances of this class, even if they compare equal, is guaranteed to work. Two or more threads operating on the same instance of this class is not guaranteed to work. Since copy-construction and move-construction is a relatively efficient operation, consider using such a copy when using this class from multiple threads.

Functions

DeleteSnapshot(std::string const &, std::string const &, Options)

Deletes the specified Snapshot resource.

Keep in mind that deleting a single snapshot might not necessarily delete all the data on that snapshot. If any data on the snapshot that is marked for deletion is needed for subsequent snapshots, the data will be moved to the next corresponding snapshot. For more information, see Deleting snapshots. https://cloud.google.com/compute/docs/reference/rest/v1/snapshots/delete

Parameters
Name Description
project std::string const &

Project ID for this request.

snapshot std::string const &

Name of the Snapshot resource to delete.

opts Options

Optional. Override the class-level options, such as retry and backoff policies.

Returns
Type Description
future< StatusOr< google::cloud::cpp::compute::v1::Operation > >

A future that becomes satisfied when the LRO (Long Running Operation) completes or the polling policy in effect for this call is exhausted. The future is satisfied with an error if the LRO completes with an error or the polling policy is exhausted. In this case the StatusOr returned by the future contains the error. If the LRO completes successfully the value of the future contains the LRO's result. For this RPC the result is a [google.cloud.cpp.compute.v1.Operation] proto message. The C++ class representing this message is created by Protobuf, using the Protobuf mapping rules.

DeleteSnapshot(NoAwaitTag, std::string const &, std::string const &, Options)

Deletes the specified Snapshot resource.

Specifying the NoAwaitTag immediately returns the [google::cloud::cpp::compute::v1::Operation] that corresponds to the Long Running Operation that has been started. No polling for operation status occurs.
