Class InstanceSummary

    • Method Detail

      • id

        public final String id()

        The ID for an instance that you created by using a specified service.

        Returns:
        The ID for an instance that you created by using a specified service.

      • hasAttributes

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

      • attributes

        public final Map<String,​String> attributes()

        A string map that contains the following information:

        • The attributes that are associated with the instance.

        • For each attribute, the applicable value.

        Supported attribute keys include the following:

        AWS_ALIAS_DNS_NAME

        For an alias record that routes traffic to an Elastic Load Balancing load balancer, the DNS name that's associated with the load balancer.

        AWS_EC2_INSTANCE_ID (HTTP namespaces only)

        The Amazon EC2 instance ID for the instance. When the AWS_EC2_INSTANCE_ID attribute is specified, then the AWS_INSTANCE_IPV4 attribute contains the primary private IPv4 address.

        AWS_INIT_HEALTH_STATUS

        If the service configuration includes HealthCheckCustomConfig, you can optionally use AWS_INIT_HEALTH_STATUS to specify the initial status of the custom health check, HEALTHY or UNHEALTHY. If you don't specify a value for AWS_INIT_HEALTH_STATUS, the initial status is HEALTHY.

        AWS_INSTANCE_CNAME

        For a CNAME record, the domain name that Route 53 returns in response to DNS queries (for example, example.com).

        AWS_INSTANCE_IPV4

        For an A record, the IPv4 address that Route 53 returns in response to DNS queries (for example, 192.0.2.44).

        AWS_INSTANCE_IPV6

        For an AAAA record, the IPv6 address that Route 53 returns in response to DNS queries (for example, 2001:0db8:85a3:0000:0000:abcd:0001:2345).

        AWS_INSTANCE_PORT

        For an SRV record, the value that Route 53 returns for the port. In addition, if the service includes HealthCheckConfig, the port on the endpoint that Route 53 sends requests to.

        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 hasAttributes() method.

        Returns:
        A string map that contains the following information:

        • The attributes that are associated with the instance.

        • For each attribute, the applicable value.

        Supported attribute keys include the following:

        AWS_ALIAS_DNS_NAME

        For an alias record that routes traffic to an Elastic Load Balancing load balancer, the DNS name that's associated with the load balancer.

        AWS_EC2_INSTANCE_ID (HTTP namespaces only)

        The Amazon EC2 instance ID for the instance. When the AWS_EC2_INSTANCE_ID attribute is specified, then the AWS_INSTANCE_IPV4 attribute contains the primary private IPv4 address.

        AWS_INIT_HEALTH_STATUS

        If the service configuration includes HealthCheckCustomConfig, you can optionally use AWS_INIT_HEALTH_STATUS to specify the initial status of the custom health check, HEALTHY or UNHEALTHY. If you don't specify a value for AWS_INIT_HEALTH_STATUS, the initial status is HEALTHY.

        AWS_INSTANCE_CNAME

        For a CNAME record, the domain name that Route 53 returns in response to DNS queries (for example, example.com).

        AWS_INSTANCE_IPV4

        For an A record, the IPv4 address that Route 53 returns in response to DNS queries (for example, 192.0.2.44).

        AWS_INSTANCE_IPV6

        For an AAAA record, the IPv6 address that Route 53 returns in response to DNS queries (for example, 2001:0db8:85a3:0000:0000:abcd:0001:2345).

        AWS_INSTANCE_PORT

        For an SRV record, the value that Route 53 returns for the port. In addition, if the service includes HealthCheckConfig, the port on the endpoint that Route 53 sends requests to.
