    • stackPolicyDuringUpdateBody

      public final String stackPolicyDuringUpdateBody()

      Structure containing the temporary overriding stack policy body. You can specify either the StackPolicyDuringUpdateBody or the StackPolicyDuringUpdateURL parameter, but not both.

      If you want to update protected resources, specify a temporary overriding stack policy during this update. If you don't specify a stack policy, the current policy that is associated with the stack will be used.

      Returns:
      Structure containing the temporary overriding stack policy body. You can specify either the StackPolicyDuringUpdateBody or the StackPolicyDuringUpdateURL parameter, but not both.

      If you want to update protected resources, specify a temporary overriding stack policy during this update. If you don't specify a stack policy, the current policy that is associated with the stack will be used.

      If you want to update protected resources, specify a temporary overriding stack policy during this update. If you don't specify a stack policy, the current policy that is associated with the stack will be used.

    • hasParameters

      public final boolean hasParameters()
      For responses, this returns true if the service returned a value for the Parameters property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

    • parameters

      public final List<Parameter> parameters()

      A list of Parameter structures that specify input parameters for the stack. For more information, see the Parameter data type.

      Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

      This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasParameters() method.

      Returns:
      A list of Parameter structures that specify input parameters for the stack. For more information, see the Parameter data type.

    • capabilities

      public final List<Capability> capabilities()

      In some cases, you must explicitly acknowledge that your stack template contains certain capabilities in order for CloudFormation to update the stack.

      • CAPABILITY_IAM and CAPABILITY_NAMED_IAM

        Some stack templates might include resources that can affect permissions in your Amazon Web Services account; for example, by creating new Identity and Access Management (IAM) users. For those stacks, you must explicitly acknowledge this by specifying one of these capabilities.

        The following IAM resources require you to specify either the CAPABILITY_IAM or CAPABILITY_NAMED_IAM capability.

        • If you have IAM resources, you can specify either capability.

        • If you have IAM resources with custom names, you must specify CAPABILITY_NAMED_IAM.

        • If you don't specify either of these capabilities, CloudFormation returns an InsufficientCapabilities error.

        If your stack template contains these resources, we suggest that you review all permissions associated with them and edit their permissions if necessary.

        For more information, see Acknowledging IAM Resources in CloudFormation Templates.

      • CAPABILITY_AUTO_EXPAND

        Some template contain macros. Macros perform custom processing on templates; this can include simple actions like find-and-replace operations, all the way to extensive transformations of entire templates. Because of this, users typically create a change set from the processed template, so that they can review the changes resulting from the macros before actually updating the stack. If your stack template contains one or more macros, and you choose to update a stack directly from the processed template, without first reviewing the resulting changes in a change set, you must acknowledge this capability. This includes the AWS::Include and AWS::Serverless transforms, which are macros hosted by CloudFormation.

        If you want to update a stack from a stack template that contains macros and nested stacks, you must update the stack directly from the template using this capability.

        You should only update stacks directly from a stack template that contains macros if you know what processing the macro performs.

        Each macro relies on an underlying Lambda service function for processing stack templates. Be aware that the Lambda function owner can update the function operation without CloudFormation being notified.

        For more information, see Using CloudFormation Macros to Perform Custom Processing on Templates.

      Only one of the Capabilities and ResourceType parameters can be specified.

      Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

      This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasCapabilities() method.

      Returns:

    • hasResourceTypes

      public final boolean hasResourceTypes()
      For responses, this returns true if the service returned a value for the ResourceTypes property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map.

    • resourceTypes

      public final List<String> resourceTypes()

      The template resource types that you have permissions to work with for this update stack action, such as AWS::EC2::Instance, AWS::EC2::*, or Custom::MyCustomInstance.

      If the list of resource types doesn't include a resource that you're updating, the stack update fails. By default, CloudFormation grants permissions to all resource types. Identity and Access Management (IAM) uses this parameter for CloudFormation-specific condition keys in IAM policies. For more information, see Controlling Access with Identity and Access Management.

      Only one of the Capabilities and ResourceType parameters can be specified.

      Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

      This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasResourceTypes() method.

    • roleARN

      public final String roleARN()

      The Amazon Resource Name (ARN) of an Identity and Access Management (IAM) role that CloudFormation assumes to update the stack. CloudFormation uses the role's credentials to make calls on your behalf. CloudFormation always uses this role for all future operations on the stack. Provided that users have permission to operate on the stack, CloudFormation uses this role even if the users don't have permission to pass it. Ensure that the role grants least privilege.

      If you don't specify a value, CloudFormation uses the role that was previously associated with the stack. If no role is available, CloudFormation uses a temporary session that is generated from your user credentials.

      Returns:

    • stackPolicyBody

      public final String stackPolicyBody()

      Structure containing a new stack policy body. You can specify either the StackPolicyBody or the StackPolicyURL parameter, but not both.

      You might update the stack policy, for example, in order to protect a new resource that you created during a stack update. If you don't specify a stack policy, the current policy that is associated with the stack is unchanged.

      Returns:
      Structure containing a new stack policy body. You can specify either the StackPolicyBody or the StackPolicyURL parameter, but not both.

      You might update the stack policy, for example, in order to protect a new resource that you created during a stack update. If you don't specify a stack policy, the current policy that is associated with the stack is unchanged.

    • stackPolicyURL

      public final String stackPolicyURL()

      Location of a file containing the updated stack policy. The URL must point to a policy (max size: 16KB) located in an S3 bucket in the same Region as the stack. The location for an Amazon S3 bucket must start with https://. You can specify either the StackPolicyBody or the StackPolicyURL parameter, but not both.

      You might update the stack policy, for example, in order to protect a new resource that you created during a stack update. If you don't specify a stack policy, the current policy that is associated with the stack is unchanged.

    • hasNotificationARNs

      public final boolean hasNotificationARNs()
      For responses, this returns true if the service returned a value for the NotificationARNs property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

    • notificationARNs

      public final List<String> notificationARNs()

      Amazon Simple Notification Service topic Amazon Resource Names (ARNs) that CloudFormation associates with the stack. Specify an empty list to remove all notification topics.

      Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

      This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasNotificationARNs() method.

      Returns:
      Amazon Simple Notification Service topic Amazon Resource Names (ARNs) that CloudFormation associates with the stack. Specify an empty list to remove all notification topics.

    • hasTags

      public final boolean hasTags()
      For responses, this returns true if the service returned a value for the Tags property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

    • tags

      public final List<Tag> tags()

      Key-value pairs to associate with this stack. CloudFormation also propagates these tags to supported resources in the stack. You can specify a maximum number of 50 tags.

      If you don't specify this parameter, CloudFormation doesn't modify the stack's tags. If you specify an empty value, CloudFormation removes all associated tags.

      Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

      This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasTags() method.

      Returns:
      Key-value pairs to associate with this stack. CloudFormation also propagates these tags to supported resources in the stack. You can specify a maximum number of 50 tags.

      If you don't specify this parameter, CloudFormation doesn't modify the stack's tags. If you specify an empty value, CloudFormation removes all associated tags.

    • disableRollback

      public final Boolean disableRollback()

      Preserve the state of previously provisioned resources when an operation fails.

      Default: False

      Returns:
      Preserve the state of previously provisioned resources when an operation fails.

      Default: False

    • clientRequestToken

      public final String clientRequestToken()

      A unique identifier for this UpdateStack request. Specify this token if you plan to retry requests so that CloudFormation knows that you're not attempting to update a stack with the same name. You might retry UpdateStack requests to ensure that CloudFormation successfully received them.

      All events triggered by a given stack operation are assigned the same client request token, which you can use to track operations. For example, if you execute a CreateStack operation with the token token1, then all the StackEvents generated by that operation will have ClientRequestToken set as token1.

      In the console, stack operations display the client request token on the Events tab. Stack operations that are initiated from the console use the token format Console-StackOperation-ID, which helps you easily identify the stack operation . For example, if you create a stack using the console, each stack event would be assigned the same token in the following format: Console-CreateStack-7f59c3cf-00d2-40c7-b2ff-e75db0987002.

      Returns:
      A unique identifier for this UpdateStack request. Specify this token if you plan to retry requests so that CloudFormation knows that you're not attempting to update a stack with the same name. You might retry UpdateStack requests to ensure that CloudFormation successfully received them.

    • retainExceptOnCreate

      public final Boolean retainExceptOnCreate()

      When set to true, newly created resources are deleted when the operation rolls back. This includes newly created resources marked with a deletion policy of Retain.

      Default: false

      Returns:
      When set to true, newly created resources are deleted when the operation rolls back. This includes newly created resources marked with a deletion policy of Retain.

      Default: false
