Class ControlServiceClient (2.21.0)

Service for modifying Control.

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

CreateControl(std::string const &, google::cloud::retail::v2::Control const &, std::string const &, Options)

Creates a Control.

If the Control to create already exists, an ALREADY_EXISTS error is returned.

Parameters
Name	Description
`parent`	`std::string const &` Required. Full resource name of parent catalog. Format: `projects/{project_number}/locations/{location_id}/catalogs/{catalog_id}`
`control`	`google::cloud::retail::v2::Control const &` Required. The Control to create.
`control_id`	`std::string const &` Required. The ID to use for the Control, which will become the final component of the Control's resource name. This value should be 4-63 characters, and valid characters are /[a-z][0-9]-_/.
`opts`	`Options` Optional. Override the class-level options, such as retry and backoff policies.

Returns
Type	Description
`StatusOr< google::cloud::retail::v2::Control >`	the result of the RPC. The response message type (google.cloud.retail.v2.Control) is mapped to a C++ class using the Protobuf mapping rules. If the request fails, the `StatusOr` contains the error details.

CreateControl(google::cloud::retail::v2::CreateControlRequest const &, Options)

Returns
Type	Description
`Status`	a `Status` object. If the request failed, the status contains the details of the failure.

Type Description

StreamRange< google::cloud::retail::v2::Control >

a StreamRange to iterate of the results. See the documentation of this type for details. In brief, this class has begin() and end() member functions returning a iterator class meeting the input iterator requirements. The value type for this iterator is a StatusOr as the iteration may fail even after some values are retrieved successfully, for example, if there is a network disconnect. An empty set of results does not indicate an error, it indicates that there are no resources meeting the request criteria. On a successful iteration the StatusOr<T> contains elements of type google.cloud.retail.v2.Control, or rather, the C++ class generated by Protobuf from that type. Please consult the Protobuf documentation for details on the Protobuf mapping rules.

ListControls(google::cloud::retail::v2::ListControlsRequest, Options)

Lists all Controls by their parent [Catalog][google.cloud.retail.v2.Catalog].
