implements com.google.api.gax.core.BackgroundResource

Service Description: Retrieves the Google Cloud Console billing accounts and associates them with projects.

This class provides the ability to make remote calls to the backing service through method calls that map to API methods. Sample code to get started:


 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 try (CloudBillingClient cloudBillingClient = CloudBillingClient.create()) {
   BillingAccountName name = BillingAccountName.ofBillingAccountName("[BILLING_ACCOUNT]");
   BillingAccount response = cloudBillingClient.getBillingAccount(name);
 }

Note: close() needs to be called on the CloudBillingClient object to clean up resources such as threads. In the example above, try-with-resources is used, which automatically calls close().

Methods
Method	Description	Method Variants
GetBillingAccount	Gets information about a billing account. The current authenticated user must be a [viewer of the billing account](https://cloud.google.com/billing/docs/how-to/billing-access).	Request object method variants only take one parameter, a request object, which must be constructed before the call. getBillingAccount(GetBillingAccountRequest request) "Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method. getBillingAccount(BillingAccountName name) getBillingAccount(String name) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. getBillingAccountCallable()
ListBillingAccounts	Lists the billing accounts that the current authenticated user has permission to [view](https://cloud.google.com/billing/docs/how-to/billing-access).	Request object method variants only take one parameter, a request object, which must be constructed before the call. listBillingAccounts(ListBillingAccountsRequest request) "Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method. listBillingAccounts() listBillingAccounts(String parent) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. listBillingAccountsPagedCallable() listBillingAccountsCallable()
UpdateBillingAccount	Updates a billing account's fields. Currently the only field that can be edited is `display_name`. The current authenticated user must have the `billing.accounts.update` IAM permission, which is typically given to the [administrator](https://cloud.google.com/billing/docs/how-to/billing-access) of the billing account.	Request object method variants only take one parameter, a request object, which must be constructed before the call. updateBillingAccount(UpdateBillingAccountRequest request) "Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method. updateBillingAccount(BillingAccountName name, BillingAccount account) updateBillingAccount(String name, BillingAccount account) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. updateBillingAccountCallable()
CreateBillingAccount	This method creates [billing subaccounts](https://cloud.google.com/billing/docs/concepts#subaccounts). Google Cloud resellers should use the Channel Services APIs, [accounts.customers.create](https://cloud.google.com/channel/docs/reference/rest/v1/accounts.customers/create) and [accounts.customers.entitlements.create](https://cloud.google.com/channel/docs/reference/rest/v1/accounts.customers.entitlements/create). When creating a subaccount, the current authenticated user must have the `billing.accounts.update` IAM permission on the parent account, which is typically given to billing account [administrators](https://cloud.google.com/billing/docs/how-to/billing-access). This method will return an error if the parent account has not been provisioned for subaccounts.	Request object method variants only take one parameter, a request object, which must be constructed before the call. createBillingAccount(CreateBillingAccountRequest request) "Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method. createBillingAccount(BillingAccount billingAccount) createBillingAccount(BillingAccount billingAccount, String parent) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. createBillingAccountCallable()
ListProjectBillingInfo	Lists the projects associated with a billing account. The current authenticated user must have the `billing.resourceAssociations.list` IAM permission, which is often given to billing account [viewers](https://cloud.google.com/billing/docs/how-to/billing-access).	Request object method variants only take one parameter, a request object, which must be constructed before the call. listProjectBillingInfo(ListProjectBillingInfoRequest request) "Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method. listProjectBillingInfo(BillingAccountName name) listProjectBillingInfo(String name) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. listProjectBillingInfoPagedCallable() listProjectBillingInfoCallable()
GetProjectBillingInfo	Gets the billing information for a project. The current authenticated user must have the `resourcemanager.projects.get` permission for the project, which can be granted by assigning the [Project Viewer](https://cloud.google.com/iam/docs/understanding-roles#predefined_roles) role.	Request object method variants only take one parameter, a request object, which must be constructed before the call. getProjectBillingInfo(GetProjectBillingInfoRequest request) "Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method. getProjectBillingInfo(ProjectName name) getProjectBillingInfo(String name) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. getProjectBillingInfoCallable()
UpdateProjectBillingInfo	Sets or updates the billing account associated with a project. You specify the new billing account by setting the `billing_account_name` in the `ProjectBillingInfo` resource to the resource name of a billing account. Associating a project with an open billing account enables billing on the project and allows charges for resource usage. If the project already had a billing account, this method changes the billing account used for resource usage charges. Note: Incurred charges that have not yet been reported in the transaction history of the Google Cloud Console might be billed to the new billing account, even if the charge occurred before the new billing account was assigned to the project. The current authenticated user must have ownership privileges for both the [project](https://cloud.google.com/docs/permissions-overview#h.bgs0oxofvnoo ) and the [billing account](https://cloud.google.com/billing/docs/how-to/billing-access). You can disable billing on the project by setting the `billing_account_name` field to empty. This action disassociates the current billing account from the project. Any billable activity of your in-use services will stop, and your application could stop functioning as expected. Any unbilled charges to date will be billed to the previously associated account. The current authenticated user must be either an owner of the project or an owner of the billing account for the project. Note that associating a project with a closed billing account will have much the same effect as disabling billing on the project: any paid resources used by the project will be shut down. Thus, unless you wish to disable billing, you should always call this method with the name of an open* billing account.	Request object method variants only take one parameter, a request object, which must be constructed before the call. updateProjectBillingInfo(UpdateProjectBillingInfoRequest request) "Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method. updateProjectBillingInfo(String name, ProjectBillingInfo projectBillingInfo) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. updateProjectBillingInfoCallable()
GetIamPolicy	Gets the access control policy for a billing account. The caller must have the `billing.accounts.getIamPolicy` permission on the account, which is often given to billing account [viewers](https://cloud.google.com/billing/docs/how-to/billing-access).	Request object method variants only take one parameter, a request object, which must be constructed before the call. getIamPolicy(GetIamPolicyRequest request) "Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method. getIamPolicy(ResourceName resource) getIamPolicy(String resource) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. getIamPolicyCallable()
SetIamPolicy	Sets the access control policy for a billing account. Replaces any existing policy. The caller must have the `billing.accounts.setIamPolicy` permission on the account, which is often given to billing account [administrators](https://cloud.google.com/billing/docs/how-to/billing-access).	Request object method variants only take one parameter, a request object, which must be constructed before the call. setIamPolicy(SetIamPolicyRequest request) "Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method. setIamPolicy(ResourceName resource, Policy policy) setIamPolicy(String resource, Policy policy) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. setIamPolicyCallable()
TestIamPermissions	Tests the access control policy for a billing account. This method takes the resource and a set of permissions as input and returns the subset of the input permissions that the caller is allowed for that resource.	Request object method variants only take one parameter, a request object, which must be constructed before the call. testIamPermissions(TestIamPermissionsRequest request) "Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method. testIamPermissions(ResourceName resource, List<String> permissions) testIamPermissions(String resource, List<String> permissions) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. testIamPermissionsCallable()
MoveBillingAccount	Changes which parent organization a billing account belongs to.	Request object method variants only take one parameter, a request object, which must be constructed before the call. moveBillingAccount(MoveBillingAccountRequest request) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. moveBillingAccountCallable()

See the individual methods for example code.

Many parameters require resource names to be formatted in a particular way. To assist with these names, this class includes a format method for each type of name, and additionally a parse method to extract the individual identifiers contained within names that are returned.

This class can be customized by passing in a custom instance of CloudBillingSettings to create(). For example:

To customize credentials:


 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 CloudBillingSettings cloudBillingSettings =
     CloudBillingSettings.newBuilder()
         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
         .build();
 CloudBillingClient cloudBillingClient = CloudBillingClient.create(cloudBillingSettings);

To customize the endpoint:


 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 CloudBillingSettings cloudBillingSettings =
     CloudBillingSettings.newBuilder().setEndpoint(myEndpoint).build();
 CloudBillingClient cloudBillingClient = CloudBillingClient.create(cloudBillingSettings);

To use REST (HTTP1.1/JSON) transport (instead of gRPC) for sending and receiving requests over the wire:


 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 CloudBillingSettings cloudBillingSettings = CloudBillingSettings.newHttpJsonBuilder().build();
 CloudBillingClient cloudBillingClient = CloudBillingClient.create(cloudBillingSettings);
