  • Method Details

    • getNode

      @Stability(Stable) @NotNull default software.constructs.Node getNode()
      The tree node.
      Specified by:
      getNode in interface software.constructs.IConstruct
      Specified by:
      getNode in interface software.constructs.IConstruct.Jsii$Default

    • getEnv

      @Stability(Stable) @NotNull default ResourceEnvironment getEnv()
      The environment this resource belongs to.

      For resources that are created and managed by the CDK (generally, those created by creating new class instances like Role, Bucket, etc.), this is always the same as the environment of the stack they belong to; however, for imported resources (those obtained from static methods like fromRoleArn, fromBucketName, etc.), that might be different than the stack they were imported into.

      Specified by:
      getEnv in interface IResource
      Specified by:
      getEnv in interface IResource.Jsii$Default

    • getStack

      @Stability(Stable) @NotNull default Stack getStack()
      The stack in which this resource is defined.
      Specified by:
      getStack in interface IResource
      Specified by:
      getStack in interface IResource.Jsii$Default

    • getPlacementGroupName

      @Stability(Stable) @NotNull default String getPlacementGroupName()
      The name of this placement group.
      Specified by:
      getPlacementGroupName in interface IPlacementGroup

    • getPartitions

      @Stability(Stable) @Nullable default Number getPartitions()
      The number of partitions.

      Valid only when Strategy is set to PARTITION.

      Default: 0

      Specified by:
      getPartitions in interface IPlacementGroup

    • getSpreadLevel

      @Stability(Stable) @Nullable default PlacementGroupSpreadLevel getSpreadLevel()
      Places instances on distinct hardware.

      Spread placement groups are recommended for applications that have a small number of critical instances that should be kept separate from each other. Launching instances in a spread level placement group reduces the risk of simultaneous failures that might occur when instances share the same equipment. Spread level placement groups provide access to distinct hardware, and are therefore suitable for mixing instance types or launching instances over time. If you start or launch an instance in a spread placement group and there is insufficient unique hardware to fulfill the request, the request fails. Amazon EC2 makes more distinct hardware available over time, so you can try your request again later. Placement groups can spread instances across racks or hosts. You can use host level spread placement groups only with AWS Outposts.

      Default: - no spread level

      Specified by:
      getSpreadLevel in interface IPlacementGroup

    • getStrategy

      @Stability(Stable) @Nullable default PlacementGroupStrategy getStrategy()
      Which strategy to use when launching instances.

      Default: - `PlacementGroupStrategy.PARTITION` if `partitions` is defined, `CLUSTER` otherwise

      Specified by:
      getStrategy in interface IPlacementGroup

    • applyRemovalPolicy

      @Stability(Stable) default void applyRemovalPolicy(@NotNull RemovalPolicy policy)
      Apply the given removal policy to this resource.

      The Removal Policy controls what happens to this resource when it stops being managed by CloudFormation, either because you've removed it from the CDK application or because you've made a change that requires the resource to be replaced.

      The resource can be deleted (RemovalPolicy.DESTROY), or left in your AWS account for data recovery and cleanup later (RemovalPolicy.RETAIN).

      Specified by:
      applyRemovalPolicy in interface IResource
      Specified by:
      applyRemovalPolicy in interface IResource.Jsii$Default
      Parameters:
      policy - This parameter is required.
