Product Reference

Service Description: Service for Branch Management

Branches are automatically created when a Catalog is created. There are fixed three branches in each catalog, and may use ListBranches method to get the details of all branches.

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 (BranchServiceClient branchServiceClient = BranchServiceClient.create()) {
   CatalogName parent = CatalogName.of("[PROJECT]", "[LOCATION]", "[CATALOG]");
   ListBranchesResponse response = branchServiceClient.listBranches(parent);
 }
 

Note: close() needs to be called on the BranchServiceClient 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
ListBranches	Lists all Branchs under the specified parent Catalog.	Request object method variants only take one parameter, a request object, which must be constructed before the call. listBranches(ListBranchesRequest request) "Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method. listBranches(CatalogName parent) listBranches(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. listBranchesCallable()
GetBranch	Retrieves a Branch.	Request object method variants only take one parameter, a request object, which must be constructed before the call. getBranch(GetBranchRequest request) "Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method. getBranch(BranchName name) getBranch(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. getBranchCallable()

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 BranchServiceSettings 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
 BranchServiceSettings branchServiceSettings =
     BranchServiceSettings.newBuilder()
         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
         .build();
 BranchServiceClient branchServiceClient = BranchServiceClient.create(branchServiceSettings);
 

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
 BranchServiceSettings branchServiceSettings =
     BranchServiceSettings.newBuilder().setEndpoint(myEndpoint).build();
 BranchServiceClient branchServiceClient = BranchServiceClient.create(branchServiceSettings);
 

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
 BranchServiceSettings branchServiceSettings =
     BranchServiceSettings.newHttpJsonBuilder().build();
 BranchServiceClient branchServiceClient = BranchServiceClient.create(branchServiceSettings);
