Class ProjectsClient (2.26.0)

Manages Google Cloud Projects.

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

GetProject(std::string const &, Options)

Retrieves the project identified by the specified name (for example, projects/415104041262).

The caller must have resourcemanager.projects.get permission for this project.

Parameters
Name	Description
`name`	`std::string const &` Required. The name of the project (for example, `projects/415104041262`).
`opts`	`Options` Optional. Override the class-level options, such as retry and backoff policies.

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

GetProject(google::cloud::resourcemanager::v3::GetProjectRequest const &, Options)

Retrieves the project identified by the specified name (for example, projects/415104041262).

The caller must have resourcemanager.projects.get permission for this project.

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

ListProjects(std::string const &, Options)

Lists projects that are direct children of the specified folder or organization resource.

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

Parameters
Name	Description
`parent`	`std::string const &` Required. The name of the parent resource whose projects 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}`.
`opts`	`Options` Optional. Override the class-level options, such as retry and backoff policies.

Returns

Type Description

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

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

ListProjects(google::cloud::resourcemanager::v3::ListProjectsRequest, Options)

Lists projects that are direct children of the specified folder or organization resource.

SearchProjects(std::string const &, Options)

Search for projects that the caller has both resourcemanager.projects.get permission on, and also satisfy the specified query.

This method returns projects in an unspecified order.

This method is eventually consistent with project mutations; this means that a newly created project may not appear in the results or recent updates to an existing project may not be reflected in the results. To retrieve the latest state of a project, use the GetProject method.

Parameters
Name	Description
`query`	`std::string const &` Optional. A query string for searching for projects that the caller has `resourcemanager.projects.get` permission to. If multiple fields are included in the query, then it will return results that match any of the fields. For more information, see SearchProjectsRequest.
`opts`	`Options` Optional. Override the class-level options, such as retry and backoff policies.

Returns

Type Description

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

CreateProject(google::cloud::resourcemanager::v3::Project const &, Options)

Request that a new project be created.

The result is an Operation which can be used to track the creation process. This process usually takes a few seconds, but can sometimes take much longer. The tracking Operation is automatically deleted after a few hours, so there is no need to call DeleteOperation.

Parameters
Name	Description
`project`	`google::cloud::resourcemanager::v3::Project const &` Required. The Project to create. Project ID is required. If the requested ID is unavailable, the request fails. If the `parent` field is set, the `resourcemanager.projects.create` permission is checked on the parent resource. If no parent is set and the authorization credentials belong to an Organization, the parent will be set to that Organization.
`opts`	`Options` Optional. Override the class-level options, such as retry and backoff policies.

Returns

Type Description

future< StatusOr< google::cloud::resourcemanager::v3::Project > >

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.resourcemanager.v3.Project proto message. The C++ class representing this message is created by Protobuf, using the Protobuf mapping rules.

DeleteProject(std::string const &, Options)

Marks the project identified by the specified name (for example, projects/415104041262) for deletion.

This method will only affect the project if it has a lifecycle state of ACTIVE.

This method changes the Project's lifecycle state from ACTIVE to DELETE_REQUESTED. The deletion starts at an unspecified time, at which point the Project is no longer accessible.

Until the deletion completes, you can check the lifecycle state checked by retrieving the project with [GetProject] [google.cloud.resourcemanager.v3.Projects.GetProject], and the project remains visible to [ListProjects] [google.cloud.resourcemanager.v3.Projects.ListProjects]. However, you cannot update the project.

After the deletion completes, the project is not retrievable by the [GetProject] [google.cloud.resourcemanager.v3.Projects.GetProject], [ListProjects] [google.cloud.resourcemanager.v3.Projects.ListProjects], and SearchProjects methods.

This method behaves idempotently, such that deleting a DELETE_REQUESTED project will not cause an error, but also won't do anything.

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

SetIamPolicy(std::string const &, google::iam::v1::Policy const &, Options)

Sets the IAM access control policy for the specified project, in the format projects/{ProjectIdOrNumber} e.g.

projects/123.

CAUTION: This method will replace the existing policy, and cannot be used to append additional IAM settings.

Note: Removing service accounts from policies or changing their roles can render services completely inoperable. It is important to understand how the service account is being used before removing or updating its roles.

The following constraints apply when using setIamPolicy():

Project does not support allUsers and allAuthenticatedUsers as members in a Binding of a Policy.
The owner role can be granted to a user, serviceAccount, or a group that is part of an organization. For example, group@myownpersonaldomain.com could be added as an owner to a project in the myownpersonaldomain.com organization, but not the examplepetstore.com organization.
Service accounts can be made owners of a project directly without any restrictions. However, to be added as an owner, a user must be invited using the Cloud Platform console and must accept the invitation.
A user cannot be granted the owner role using setIamPolicy(). The user must be granted the owner role using the Cloud Platform Console and must explicitly accept the invitation.
Invitations to grant the owner role cannot be sent using setIamPolicy(); they must be sent only using the Cloud Platform Console.
If the project is not part of an organization, there must be at least one owner who has accepted the Terms of Service (ToS) agreement in the policy. Calling setIamPolicy() to remove the last ToS-accepted owner from the policy will fail. This restriction also applies to legacy projects that no longer have owners who have accepted the ToS. Edits to IAM policies will be rejected until the lack of a ToS-accepting owner is rectified. If the project is part of an organization, you can remove all owners, potentially making the organization inaccessible.

Parameters
Name	Description
`resource`	`std::string const &` REQUIRED: The resource for which the policy is being specified. See the operation documentation for the appropriate value for this field.
`policy`	`google::iam::v1::Policy const &` REQUIRED: The complete policy to be applied to the `resource`. The size of the policy is limited to a few 10s of KB. An empty policy is a valid policy but certain Cloud Platform services (such as Projects) might reject them.
`opts`	`Options` Optional. Override the class-level options, such as retry and backoff policies.

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

SetIamPolicy(google::iam::v1::SetIamPolicyRequest const &, Options)

Sets the IAM access control policy for the specified project, in the format projects/{ProjectIdOrNumber} e.g.

projects/123.

CAUTION: This method will replace the existing policy, and cannot be used to append additional IAM settings.

The following constraints apply when using setIamPolicy():

Project does not support allUsers and allAuthenticatedUsers as members in a Binding of a Policy.
The owner role can be granted to a user, serviceAccount, or a group that is part of an organization. For example, group@myownpersonaldomain.com could be added as an owner to a project in the myownpersonaldomain.com organization, but not the examplepetstore.com organization.
Service accounts can be made owners of a project directly without any restrictions. However, to be added as an owner, a user must be invited using the Cloud Platform console and must accept the invitation.
A user cannot be granted the owner role using setIamPolicy(). The user must be granted the owner role using the Cloud Platform Console and must explicitly accept the invitation.
Invitations to grant the owner role cannot be sent using setIamPolicy(); they must be sent only using the Cloud Platform Console.
If the project is not part of an organization, there must be at least one owner who has accepted the Terms of Service (ToS) agreement in the policy. Calling setIamPolicy() to remove the last ToS-accepted owner from the policy will fail. This restriction also applies to legacy projects that no longer have owners who have accepted the ToS. Edits to IAM policies will be rejected until the lack of a ToS-accepting owner is rectified. If the project is part of an organization, you can remove all owners, potentially making the organization inaccessible.

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

TestIamPermissions(std::string const &, std::vector< std::string > const &, Options)

Returns permissions that a caller has on the specified project, in the format projects/{ProjectIdOrNumber} e.g.

projects/123..

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 project, in the format projects/{ProjectIdOrNumber} e.g.

projects/123..
