Class FoldersClient (2.30.0)

Manages Cloud Platform folder resources.

Folders can be used to organize the resources under an organization and to control the policies applied to groups of resources.

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

GetFolder(std::string const &, Options)

Retrieves a folder identified by the supplied resource name.

Valid folder resource names have the format folders/{folder_id} (for example, folders/1234). The caller must have resourcemanager.folders.get permission on the identified folder.

Parameters
Name	Description
`name`	`std::string const &` Required. The resource name of the folder to retrieve. Must be of the form `folders/{folder_id}`.
`opts`	`Options` Optional. Override the class-level options, such as retry and backoff policies.

Returns
Type	Description
`StatusOr< google::cloud::resourcemanager::v3::Folder >`	the result of the RPC. The response message type (google.cloud.resourcemanager.v3.Folder) is mapped to a C++ class using the Protobuf mapping rules. If the request fails, the `StatusOr` contains the error details.

GetFolder(google::cloud::resourcemanager::v3::GetFolderRequest const &, Options)

Retrieves a folder identified by the supplied resource name.

Valid folder resource names have the format folders/{folder_id} (for example, folders/1234). The caller must have resourcemanager.folders.get permission on the identified folder.

Parameters
Name	Description
`request`	`google::cloud::resourcemanager::v3::GetFolderRequest const &` Unary RPCs, such as the one wrapped by this function, receive a single `request` proto message which includes all the inputs for the RPC. In this case, the proto message is a google.cloud.resourcemanager.v3.GetFolderRequest. Proto messages are converted to C++ classes by Protobuf, using the Protobuf mapping rules.
`opts`	`Options` Optional. Override the class-level options, such as retry and backoff policies.

Returns
Type	Description
`StatusOr< google::cloud::resourcemanager::v3::Folder >`	the result of the RPC. The response message type (google.cloud.resourcemanager.v3.Folder) is mapped to a C++ class using the Protobuf mapping rules. If the request fails, the `StatusOr` contains the error details.

ListFolders(std::string const &, Options)

Lists the folders that are direct descendants of supplied parent resource.

list() provides a strongly consistent view of the folders underneath the specified parent resource. list() returns folders sorted based upon the (ascending) lexical ordering of their display_name. The caller must have resourcemanager.folders.list permission on the identified parent.

Parameters
Name	Description
`parent`	`std::string const &` Required. The name of the parent resource whose folders are being listed. Only children of this parent resource are listed; descendants are not listed. If the parent is a folder, use the value `folders/{folder_id}`. If the parent is an organization, use the value `organizations/{org_id}`. Access to this method is controlled by checking the `resourcemanager.folders.list` permission on the `parent`.
`opts`	`Options` Optional. Override the class-level options, such as retry and backoff policies.

Returns

Type Description

StreamRange< google::cloud::resourcemanager::v3::Folder >

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.resourcemanager.v3.Folder, or rather, the C++ class generated by Protobuf from that type. Please consult the Protobuf documentation for details on the Protobuf mapping rules.

ListFolders(google::cloud::resourcemanager::v3::ListFoldersRequest, Options)

Lists the folders that are direct descendants of supplied parent resource.

CreateFolder(google::cloud::resourcemanager::v3::Folder const &, Options)

Creates a folder in the resource hierarchy.

Returns an Operation which can be used to track the progress of the folder creation workflow. Upon success, the Operation.response field will be populated with the created Folder.

In order to succeed, the addition of this new folder must not violate the folder naming, height, or fanout constraints.

The folder's display_name must be distinct from all other folders that share its parent.
The addition of the folder must not cause the active folder hierarchy to exceed a height of 10. Note, the full active + deleted folder hierarchy is allowed to reach a height of 20; this provides additional headroom when moving folders that contain deleted folders.
The addition of the folder must not cause the total number of folders under its parent to exceed 300.

If the operation fails due to a folder constraint violation, some errors may be returned by the CreateFolder request, with status code FAILED_PRECONDITION and an error description. Other folder constraint violations will be communicated in the Operation, with the specific PreconditionFailure returned in the details list in the Operation.error field.

The caller must have resourcemanager.folders.create permission on the identified parent.

Parameters
Name	Description
`folder`	`google::cloud::resourcemanager::v3::Folder const &` Required. The folder being created, only the display name and parent will be consulted. All other fields will be ignored.

The resource field should be the folder's resource name, for example: "folders/1234".

There are no permissions required for making this API call.

Parameters
Name	Description
`resource`	`std::string const &` REQUIRED: The resource for which the policy detail is being requested. See the operation documentation for the appropriate value for this field.
`permissions`	`std::vector< std::string > const &` The set of permissions to check for the `resource`. Permissions with wildcards (such as '' or 'storage.') are not allowed. For more information see IAM Overview.
`opts`	`Options` Optional. Override the class-level options, such as retry and backoff policies.

Returns
Type	Description
`StatusOr< google::iam::v1::TestIamPermissionsResponse >`	the result of the RPC. The response message type (google.iam.v1.TestIamPermissionsResponse) is mapped to a C++ class using the Protobuf mapping rules. If the request fails, the `StatusOr` contains the error details.

TestIamPermissions(google::iam::v1::TestIamPermissionsRequest const &, Options)

Returns permissions that a caller has on the specified folder.

The resource field should be the folder's resource name, for example: "folders/1234".

There are no permissions required for making this API call.

Parameters
Name	Description
`request`	`google::iam::v1::TestIamPermissionsRequest const &` Unary RPCs, such as the one wrapped by this function, receive a single `request` proto message which includes all the inputs for the RPC. In this case, the proto message is a google.iam.v1.TestIamPermissionsRequest. Proto messages are converted to C++ classes by Protobuf, using the Protobuf mapping rules.
`opts`	`Options` Optional. Override the class-level options, such as retry and backoff policies.

Returns
Type	Description
`StatusOr< google::iam::v1::TestIamPermissionsResponse >`	the result of the RPC. The response message type (google.iam.v1.TestIamPermissionsResponse) is mapped to a C++ class using the Protobuf mapping rules. If the request fails, the `StatusOr` contains the error details.
