Member Function Documentation

AutoScalingClient::AutoScalingClient(const QtAws::Core::AwsRegion::Region region = QtAws::Core::AwsRegion::InvalidRegion, QtAws::Core::AwsAbstractCredentials *credentials = NULL, QNetworkAccessManager * const manager = NULL, QObject * const parent = 0)

Constructs a AutoScalingClient object.

The new client object will region, credentials, and manager for network operations.

The new object will be owned by parent, if set.

AutoScalingClient::AutoScalingClient(const QUrl &endpoint, QtAws::Core::AwsAbstractCredentials *credentials = NULL, QNetworkAccessManager * const manager = NULL, QObject * const parent = 0)

This function overloads AutoScalingClient().

This overload allows the caller to specify the specific endpoint to send requests to. Typically, it is easier to use the alternative constructor, which allows the caller to specify an AWS region instead, in which case this client will determine the correct endpoint for the given region automatically (via AwsEndpoint::getEndpoint).

See also QtAws::Core::AwsEndpoint::getEndpoint.

[slot] AttachInstancesResponse *AutoScalingClient::attachInstances(const AttachInstancesRequest &request)

Sends request to the AutoScalingClient service, and returns a pointer to an AttachInstancesResponse object to track the result.

Note: The caller is to take responsbility for the resulting pointer.

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>

If there is a Classic Load Balancer attached to your Auto Scaling group, the instances are also registered with the load balancer. If there are target groups attached to your Auto Scaling group, the instances are also registered with the target
