Class SimulatorClient (0.12.0)

Service Description: Policy Simulator API service.

Policy Simulator is a collection of endpoints for creating, running, and viewing a Replay. A Replay is a type of simulation that lets you see how your principals' access to resources might change if you changed your IAM policy.

During a Replay, Policy Simulator re-evaluates, or replays, past access attempts under both the current policy and your proposed policy, and compares those results to determine how your principals' access might change under the proposed 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:


 // 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 (SimulatorClient simulatorClient = SimulatorClient.create()) {
   ReplayName name =
       ReplayName.ofProjectLocationReplayName("[PROJECT]", "[LOCATION]", "[REPLAY]");
   Replay response = simulatorClient.getReplay(name);
 }

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

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 SimulatorSettings 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
 SimulatorSettings simulatorSettings =
     SimulatorSettings.newBuilder()
         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
         .build();
 SimulatorClient simulatorClient = SimulatorClient.create(simulatorSettings);

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
 SimulatorSettings simulatorSettings =
     SimulatorSettings.newBuilder().setEndpoint(myEndpoint).build();
 SimulatorClient simulatorClient = SimulatorClient.create(simulatorSettings);

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
 SimulatorSettings simulatorSettings = SimulatorSettings.newHttpJsonBuilder().build();
 SimulatorClient simulatorClient = SimulatorClient.create(simulatorSettings);
