Class CatalogServiceClient (2.3.0)

public class CatalogServiceClient implements BackgroundResource

Service Description: Service for managing catalog configuration.

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 for illustrative purposes only.
 // It may require modifications to work in your environment.
 try (CatalogServiceClient catalogServiceClient = CatalogServiceClient.create()) {
   Catalog catalog = Catalog.newBuilder().build();
   FieldMask updateMask = FieldMask.newBuilder().build();
   Catalog response = catalogServiceClient.updateCatalog(catalog, updateMask);
 }

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

The surface of this class includes several types of Java methods for each of the API's methods:

A "flattened" method. With this type of method, the fields of the request type have been converted into function parameters. It may be the case that not all fields are available as parameters, and not every API method will have a flattened method entry point.
A "request object" method. This type of method only takes one parameter, a request object, which must be constructed before the call. Not every API method will have a request object method.
A "callable" method. This type of method takes no parameters and returns an immutable API callable object, which can be used to initiate calls to the service.

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 CatalogServiceSettings to create(). For example:

To customize credentials:


 // This snippet has been automatically generated for illustrative purposes only.
 // It may require modifications to work in your environment.
 CatalogServiceSettings catalogServiceSettings =
     CatalogServiceSettings.newBuilder()
         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
         .build();
 CatalogServiceClient catalogServiceClient = CatalogServiceClient.create(catalogServiceSettings);

To customize the endpoint:


 // This snippet has been automatically generated for illustrative purposes only.
 // It may require modifications to work in your environment.
 CatalogServiceSettings catalogServiceSettings =
     CatalogServiceSettings.newBuilder().setEndpoint(myEndpoint).build();
 CatalogServiceClient catalogServiceClient = CatalogServiceClient.create(catalogServiceSettings);

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


 // This snippet has been automatically generated for illustrative purposes only.
 // It may require modifications to work in your environment.
 CatalogServiceSettings catalogServiceSettings =
     CatalogServiceSettings.newBuilder()
         .setTransportChannelProvider(
             CatalogServiceSettings.defaultHttpJsonTransportProviderBuilder().build())
         .build();
 CatalogServiceClient catalogServiceClient = CatalogServiceClient.create(catalogServiceSettings);

setDefaultBranch(CatalogName catalog)

public final void setDefaultBranch(CatalogName catalog)

Set a specified branch id as default branch. API methods such as SearchService.Search, ProductService.GetProduct, ProductService.ListProducts will treat requests using "default_branch" to the actual branch id set as default.

For example, if projects/*/locations/*/catalogs/*/branches/1 is set as default, setting SearchRequest.branch to projects/*/locations/*/catalogs/*/branches/default_branch is equivalent to setting SearchRequest.branch to projects/*/locations/*/catalogs/*/branches/1.

Using multiple branches can be useful when developers would like to have a staging branch to test and verify for future usage. When it becomes ready, developers switch on the staging branch using this API while keeping using projects/*/locations/*/catalogs/*/branches/default_branch as SearchRequest.branch to route the traffic to this staging branch.

CAUTION: If you have live predict/search traffic, switching the default branch could potentially cause outages if the ID space of the new branch is very different from the old one.

More specifically:

PredictionService will only return product IDs from branch {newBranch}.
SearchService will only return product IDs from branch {newBranch} (if branch is not explicitly set).
UserEventService will only join events with products from branch {newBranch}.

Sample code:


 // This snippet has been automatically generated for illustrative purposes only.
 // It may require modifications to work in your environment.
 try (CatalogServiceClient catalogServiceClient = CatalogServiceClient.create()) {
   CatalogName catalog = CatalogName.of("[PROJECT]", "[LOCATION]", "[CATALOG]");
   catalogServiceClient.setDefaultBranch(catalog);
 }

Parameter

Name	Description
catalog	`CatalogName` Full resource name of the catalog, such as `projects/*/locations/global/catalogs/default_catalog`.

setDefaultBranch(SetDefaultBranchRequest request)

public final void setDefaultBranch(SetDefaultBranchRequest request)

CAUTION: If you have live predict/search traffic, switching the default branch could potentially cause outages if the ID space of the new branch is very different from the old one.

More specifically:

PredictionService will only return product IDs from branch {newBranch}.
SearchService will only return product IDs from branch {newBranch} (if branch is not explicitly set).
UserEventService will only join events with products from branch {newBranch}.

Sample code:


 // This snippet has been automatically generated for illustrative purposes only.
