      Returns:
      The ID of the Amazon Machine Image (AMI) to use to launch your EC2 instances. For more information, see Find a Linux AMI in the Amazon EC2 User Guide for Linux Instances.

    • keyName

      public final String keyName()

      The name of the key pair.

      For more information, see Amazon EC2 key pairs and Amazon EC2 instances in the Amazon EC2 User Guide for Linux Instances.

    • hasSecurityGroups

      public final boolean hasSecurityGroups()
      For responses, this returns true if the service returned a value for the SecurityGroups 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.

    • securityGroups

      public final List<String> securityGroups()

      A list that contains the security groups to assign to the instances in the Auto Scaling group. For more information, see Control traffic to your Amazon Web Services resources using security groups in the Amazon Virtual Private Cloud User Guide.

      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 hasSecurityGroups() method.

      Returns:
      A list that contains the security groups to assign to the instances in the Auto Scaling group. For more information, see Control traffic to your Amazon Web Services resources using security groups in the Amazon Virtual Private Cloud User Guide.

    • classicLinkVPCId

      Returns:
      Available for backward compatibility.

    • hasClassicLinkVPCSecurityGroups

      public final boolean hasClassicLinkVPCSecurityGroups()
      For responses, this returns true if the service returned a value for the ClassicLinkVPCSecurityGroups 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.

    • classicLinkVPCSecurityGroups

      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 hasClassicLinkVPCSecurityGroups() method.

      Returns:
      Available for backward compatibility.
