"https://autoscaling.amazonaws.com"). If the protocol is not specified
here, the default protocol from this client's ClientConfiguration
will be used, which by default is HTTPS.
For more information on using AWS regions with the AWS SDK for Java, and a complete list of all available endpoints for all AWS services, see: http://developer.amazonwebservices.com/connect/entry.jspa?externalID= 3912
This method is not threadsafe. An endpoint should be configured when the client is created and before any service requests are made. Changing it afterwards creates inevitable race conditions for any service requests in transit or retrying.

- The endpoint (ex: "autoscaling.amazonaws.com") or a full URL,
including the protocol (ex: "https://autoscaling.amazonaws.com")
of the region specific AWS endpoint this client will communicate
with.void setRegion(Region region)
setEndpoint(String)
, sets the
regional endpoint for this client's service calls. Callers can use this
method to control which AWS region they want to work with.
By default, all service endpoints in all regions use the https protocol.
To use http instead, specify it in the ClientConfiguration
supplied at construction.
This method is not threadsafe. A region should be configured when the client is created and before any service requests are made. Changing it afterwards creates inevitable race conditions for any service requests in transit or retrying.

void attachInstances(AttachInstancesRequest attachInstancesRequest)
Attaches one or more EC2 instances to the specified Auto Scaling group.
When you attach instances, Auto Scaling increases the desired capacity of the group by the number of instances being attached. If the number of instances being attached plus the desired capacity of the group exceeds the maximum size of the group, the operation fails.
For more information, see Attach EC2 Instances to Your Auto Scaling Group in the Auto Scaling Developer Guide.

Creates or updates tags for the specified Auto Scaling group.
A tag is defined by its resource ID, resource type, key, value, and
propagate flag. The value and the propagate flag are optional parameters.
The only supported resource type is auto-scaling-group
, and
the resource ID must be the name of the group. The
PropagateAtLaunch
flag determines whether the tag is added
to instances launched in the group. Valid values are true
or
false
.
When you specify a tag with a key that already exists, the operation overwrites the previous tag definition, and you do not get an error message.
For more information, see Tagging Auto Scaling Groups and Instances in the Auto Scaling Developer Guide.

- You already have a pending update to an Auto Scaling resource
(for example, a group, instance, or load balancer).RecordLifecycleActionHeartbeatResult recordLifecycleActionHeartbeat(RecordLifecycleActionHeartbeatRequest recordLifecycleActionHeartbeatRequest)
Records a heartbeat for the lifecycle action associated with a specific
token. This extends the timeout by the length of time defined by the
HeartbeatTimeout
parameter of PutLifecycleHook.
This operation is a part of the basic sequence for adding a lifecycle hook to an Auto Scaling group:

Resumes the specified suspended Auto Scaling processes for the specified
Auto Scaling group. To resume specific processes, use the
ScalingProcesses
parameter. To resume all processes, omit
the ScalingProcesses
parameter. For more information, see Suspend and Resume Auto Scaling Processes in the Auto Scaling
Developer Guide.

Suspends the specified Auto Scaling processes for the specified Auto
Scaling group. To suspend specific processes, use the
ScalingProcesses
parameter. To suspend all processes, omit
the ScalingProcesses
parameter.
Note that if you suspend either the Launch
or
Terminate
process types, it can prevent other process types
from functioning properly.
To resume processes that have been suspended, use ResumeProcesses.
For more information, see Suspend and Resume Auto Scaling Processes in the Auto Scaling Developer Guide.

- You already have a pending update to an Auto Scaling resource
(for example, a group, instance, or load balancer).TerminateInstanceInAutoScalingGroupResult terminateInstanceInAutoScalingGroup(TerminateInstanceInAutoScalingGroupRequest terminateInstanceInAutoScalingGroupRequest)
Terminates the specified instance and optionally adjusts the desired group size.
This call simply makes a termination request. The instance is not terminated immediately.

- ScalingActivityInProgressException
- The Auto Scaling group can't be deleted because there are scaling
activities in progress.ResourceContentionException
- You already have a pending update to an Auto Scaling resource
(for example, a group, instance, or load balancer).void updateAutoScalingGroup(UpdateAutoScalingGroupRequest updateAutoScalingGroupRequest)
Updates the configuration for the specified Auto Scaling group.
To update an Auto Scaling group with a launch configuration with
InstanceMonitoring
set to False
, you must first
disable the collection of group metrics. Otherwise, you will get an
error. If you have previously enabled the collection of group metrics,
you can disable it using DisableMetricsCollection.
The new settings are registered upon the completion of this call. Any launch configuration settings take effect on any triggers after this call returns. Scaling activities that are currently in progress aren't affected.
Note the following:
If you specify a new value for MinSize
without specifying a
value for DesiredCapacity
, and the new MinSize
is larger than the current size of the group, we implicitly call
SetDesiredCapacity to set the size of the group to the new value
of MinSize
.
If you specify a new value for MaxSize
without specifying a
value for DesiredCapacity
, and the new MaxSize
is smaller than the current size of the group, we implicitly call
SetDesiredCapacity to set the size of the group to the new value
of MaxSize
.
All other optional parameters are left unchanged if not specified.
