@Generated(value="jsii-pacmak/1.84.0 (build 5404dcf)", date="2023-06-19T16:29:57.358Z") @Stability(Stable) public class PolicyStatement extends software.amazon.jsii.JsiiObject
Represents a statement in an IAM policy document.

Example: 

 // Add gateway endpoints when creating the VPC
 Vpc vpc = Vpc.Builder.create(this, "MyVpc")
         .gatewayEndpoints(Map.of(
                 "S3", GatewayVpcEndpointOptions.builder()
                         .service(GatewayVpcEndpointAwsService.S3)
                         .build()))
         .build();
 // Alternatively gateway endpoints can be added on the VPC
 GatewayVpcEndpoint dynamoDbEndpoint = vpc.addGatewayEndpoint("DynamoDbEndpoint", GatewayVpcEndpointOptions.builder()
         .service(GatewayVpcEndpointAwsService.DYNAMODB)
         .build());
 // This allows to customize the endpoint policy
 dynamoDbEndpoint.addToPolicy(
 PolicyStatement.Builder.create() // Restrict to listing and describing tables
         .principals(List.of(new AnyPrincipal()))
         .actions(List.of("dynamodb:DescribeTable", "dynamodb:ListTables"))
         .resources(List.of("*")).build());
 // Add an interface endpoint
 vpc.addInterfaceEndpoint("EcrDockerEndpoint", InterfaceVpcEndpointOptions.builder()
         .service(InterfaceVpcEndpointAwsService.ECR_DOCKER)
         .build());

    • addAccountCondition

      @Stability(Stable) public void addAccountCondition(@NotNull String accountId)
      Add a condition that limits to a given account.

      This method can only be called once: subsequent calls will overwrite earlier calls.

      Parameters:
      accountId - This parameter is required.

    • addAccountRootPrincipal

      @Stability(Stable) public void addAccountRootPrincipal()
      Adds an AWS account root user principal to this policy statement.

    • addActions

      @Stability(Stable) public void addActions(@NotNull @NotNull String... actions)
      Specify allowed actions into the "Action" section of the policy statement.

      Parameters:
      actions - actions that will be allowed. This parameter is required.
      See Also:

    • addAllResources

      @Stability(Stable) public void addAllResources()
      Adds a "*" resource to this statement.

    • addAnyPrincipal

      @Stability(Stable) public void addAnyPrincipal()
      Adds all identities in all accounts ("*") to this policy statement.

    • addArnPrincipal

      @Stability(Stable) public void addArnPrincipal(@NotNull String arn)
      Specify a principal using the ARN identifier of the principal.

      You cannot specify IAM groups and instance profiles as principals.

      Parameters:
      arn - ARN identifier of AWS account, IAM user, or IAM role (i.e. arn:aws:iam::123456789012:user/user-name). This parameter is required.

    • addAwsAccountPrincipal

      @Stability(Stable) public void addAwsAccountPrincipal(@NotNull String accountId)
      Specify AWS account ID as the principal entity to the "Principal" section of a policy statement.

      Parameters:
      accountId - This parameter is required.

    • addCanonicalUserPrincipal

      @Stability(Stable) public void addCanonicalUserPrincipal(@NotNull String canonicalUserId)
      Adds a canonical user ID principal to this policy document.

    • addCondition

      @Stability(Stable) public void addCondition(@NotNull String key, @NotNull Object value)
      Add a condition to the Policy.

      If multiple calls are made to add a condition with the same operator and field, only the last one wins. For example: 

       PolicyStatement stmt;
 stmt.addCondition("StringEquals", Map.of("aws:SomeField", "1"));
 stmt.addCondition("StringEquals", Map.of("aws:SomeField", "2"));

      Will end up with the single condition StringEquals: { 'aws:SomeField': '2' }.

      If you meant to add a condition to say that the field can be either 1 or 2, write this: 

       PolicyStatement stmt;
 stmt.addCondition("StringEquals", Map.of("aws:SomeField", List.of("1", "2")));

      Parameters:
      key - This parameter is required.
      value - This parameter is required.
