Product Reference

Service Description: An interface for managing Identity and Access Management (IAM) policies.

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 (PoliciesClient policiesClient = PoliciesClient.create()) {
   String name = "name3373707";
   Policy response = policiesClient.getPolicy(name);
 }
 

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

Methods

Method	Description	Method Variants
ListPolicies	Retrieves the policies of the specified kind that are attached to a resource. The response lists only policy metadata. In particular, policy rules are omitted.	Request object method variants only take one parameter, a request object, which must be constructed before the call. listPolicies(ListPoliciesRequest request) "Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method. listPolicies(String parent) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. listPoliciesPagedCallable() listPoliciesCallable()
GetPolicy	Gets a policy.	Request object method variants only take one parameter, a request object, which must be constructed before the call. getPolicy(GetPolicyRequest request) "Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method. getPolicy(String name) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. getPolicyCallable()
CreatePolicy	Creates a policy.	Request object method variants only take one parameter, a request object, which must be constructed before the call. createPolicyAsync(CreatePolicyRequest request) Methods that return long-running operations have "Async" method variants that return OperationFuture, which is used to track polling of the service. createPolicyAsync(String parent, Policy policy, String policyId) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. createPolicyOperationCallable() createPolicyCallable()
UpdatePolicy	Updates the specified policy. You can update only the rules and the display name for the policy. To update a policy, you should use a read-modify-write loop: 1. Use GetPolicy to read the current version of the policy. 2. Modify the policy as needed. 3. Use UpdatePolicy to write the updated policy. This pattern helps prevent conflicts between concurrent updates.	Request object method variants only take one parameter, a request object, which must be constructed before the call. updatePolicyAsync(UpdatePolicyRequest request) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. updatePolicyOperationCallable() updatePolicyCallable()
DeletePolicy	Deletes a policy. This action is permanent.	Request object method variants only take one parameter, a request object, which must be constructed before the call. deletePolicyAsync(DeletePolicyRequest request) Methods that return long-running operations have "Async" method variants that return OperationFuture, which is used to track polling of the service. deletePolicyAsync(String name) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. deletePolicyOperationCallable() deletePolicyCallable()

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 PoliciesSettings 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
 PoliciesSettings policiesSettings =
     PoliciesSettings.newBuilder()
         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
         .build();
 PoliciesClient policiesClient = PoliciesClient.create(policiesSettings);
 

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
 PoliciesSettings policiesSettings =
     PoliciesSettings.newBuilder().setEndpoint(myEndpoint).build();
 PoliciesClient policiesClient = PoliciesClient.create(policiesSettings);
 

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
 PoliciesSettings policiesSettings = PoliciesSettings.newHttpJsonBuilder().build();
 PoliciesClient policiesClient = PoliciesClient.create(policiesSettings);

updatePolicyAsync(UpdatePolicyRequest request)

public final OperationFuture<Policy,PolicyOperationMetadata> updatePolicyAsync(UpdatePolicyRequest request)

Updates the specified policy.

You can update only the rules and the display name for the policy.

To update a policy, you should use a read-modify-write loop:

1. Use GetPolicy to read the current version of the policy. 2. Modify the policy as needed. 3. Use UpdatePolicy to write the updated policy.

This pattern helps prevent conflicts between concurrent updates.

Sample code:

 // 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

updatePolicyOperationCallable()

public final OperationCallable<UpdatePolicyRequest,Policy,PolicyOperationMetadata> updatePolicyOperationCallable()

Updates the specified policy.

You can update only the rules and the display name for the policy.

To update a policy, you should use a read-modify-write loop:

1. Use GetPolicy to read the current version of the policy. 2. Modify the policy as needed. 3. Use UpdatePolicy to write the updated policy.

This pattern helps prevent conflicts between concurrent updates.
