Class SystemPolicyV1Client

public class SystemPolicyV1Client implements BackgroundResource

Service Description: API for working with the system policy.

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 (SystemPolicyV1Client systemPolicyV1Client = SystemPolicyV1Client.create()) {
   PolicyName name = PolicyName.ofProjectName("[PROJECT]");
   Resources.Policy response = systemPolicyV1Client.getSystemPolicy(name);
 }
 

Note: close() needs to be called on the SystemPolicyV1Client 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 SystemPolicyV1Settings to create(). For example:

To customize credentials:


 SystemPolicyV1Settings systemPolicyV1Settings =
     SystemPolicyV1Settings.newBuilder()
         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
         .build();
 SystemPolicyV1Client systemPolicyV1Client = SystemPolicyV1Client.create(systemPolicyV1Settings);
 

To customize the endpoint:


 SystemPolicyV1Settings systemPolicyV1Settings =
     SystemPolicyV1Settings.newBuilder().setEndpoint(myEndpoint).build();
 SystemPolicyV1Client systemPolicyV1Client = SystemPolicyV1Client.create(systemPolicyV1Settings);

SystemPolicyV1Client
Exceptions
TypeDescription
IOException

create(SystemPolicyV1Settings settings)

public static final SystemPolicyV1Client create(SystemPolicyV1Settings settings)

Constructs an instance of SystemPolicyV1Client, using the given settings. The channels are created based on the settings passed in, or defaults for any settings that are not set.

SystemPolicyV1Client
Exceptions
TypeDescription
IOException

create(SystemPolicyV1Stub stub)

public static final SystemPolicyV1Client create(SystemPolicyV1Stub stub)

Constructs an instance of SystemPolicyV1Client, using the given stub for making calls. This is for advanced usage - prefer using create(SystemPolicyV1Settings).

TypeDescription
SystemPolicyV1Client

Constructors

SystemPolicyV1Client(SystemPolicyV1Settings settings)

protected SystemPolicyV1Client(SystemPolicyV1Settings settings)

Constructs an instance of SystemPolicyV1Client, 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.
