public class CloudMemcacheClient implements BackgroundResource

Service Description: Configures and manages Cloud Memorystore for Memcached instances.

The memcache.googleapis.com service implements the Google Cloud Memorystore for Memcached API and defines the following resource model for managing Memorystore Memcached (also called Memcached below) instances:

• The service works with a collection of cloud projects, named: /projects/*
• Each project has a collection of available locations, named: /locations/*
• Each location has a collection of Memcached instances, named: /instances/*
• As such, Memcached instances are resources of the form: /projects/{project_id}/locations/{location_id}/instances/{instance_id}

Note that location_id must be a GCP region; for example:

• projects/my-memcached-project/locations/us-central1/instances/my-memcached

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 (CloudMemcacheClient cloudMemcacheClient = CloudMemcacheClient.create()) {
   InstanceName name = InstanceName.of("[PROJECT]", "[LOCATION]", "[INSTANCE]");
   Instance response = cloudMemcacheClient.getInstance(name);
 }
 

Note: close() needs to be called on the CloudMemcacheClient 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:

1. 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.
2. 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.
3. 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 CloudMemcacheSettings 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
 CloudMemcacheSettings cloudMemcacheSettings =
     CloudMemcacheSettings.newBuilder()
         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
         .build();
 CloudMemcacheClient cloudMemcacheClient = CloudMemcacheClient.create(cloudMemcacheSettings);
 

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
 CloudMemcacheSettings cloudMemcacheSettings =
     CloudMemcacheSettings.newBuilder().setEndpoint(myEndpoint).build();
 CloudMemcacheClient cloudMemcacheClient = CloudMemcacheClient.create(cloudMemcacheSettings);
 

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
 CloudMemcacheSettings cloudMemcacheSettings =
     CloudMemcacheSettings.newHttpJsonBuilder().build();
 CloudMemcacheClient cloudMemcacheClient = CloudMemcacheClient.create(cloudMemcacheSettings);
