All Implemented Interfaces:

BackgroundResource, AutoCloseable

@Generated(value="by gapic-generator")
 @BetaApi
public class RegionClient
extends Object
implements BackgroundResource

Service Description: Creates and runs virtual machines on Google Cloud Platform.

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:

 
 try (RegionClient regionClient = RegionClient.create()) {
   ProjectRegionName region = ProjectRegionName.of("[PROJECT]", "[REGION]");
   Region response = regionClient.getRegion(region);
 }
 
 

Note: close() needs to be called on the regionClient 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 RegionSettings to create(). For example:

To customize credentials:

 
 RegionSettings regionSettings =
     RegionSettings.newBuilder()
         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
         .build();
 RegionClient regionClient =
     RegionClient.create(regionSettings);
 
 

To customize the endpoint:

 
 RegionSettings regionSettings =
     RegionSettings.newBuilder().setEndpoint(myEndpoint).build();
 RegionClient regionClient =
     RegionClient.create(regionSettings);

Constructor Detail

RegionClient

protected RegionClient(RegionSettings settings)
                throws IOException

Constructs an instance of RegionClient, using the given settings. This is protected so that it is easy to make a subclass, but otherwise, the static factory methods should be preferred.

Throws:

IOException

RegionClient

@BetaApi(value="A restructuring of stub classes is planned, so this may break in the future")
protected RegionClient(RegionStub stub)

Method Detail

create

public static final RegionClient create()
                                 throws IOException

Throws:

IOException

create

public static final RegionClient create(RegionSettings settings)
                                 throws IOException

Constructs an instance of RegionClient, using the given settings. The channels are created based on the settings passed in, or defaults for any settings that are not set.

Throws:

IOException

create

@BetaApi(value="A restructuring of stub classes is planned, so this may break in the future")
public static final RegionClient create(RegionStub stub)

Constructs an instance of RegionClient, using the given stub for making calls. This is for advanced usage - prefer to use RegionSettings}.
