- Method Detail
  - instanceGroupId
```
public final String instanceGroupId()
```
    Unique ID of the instance group to modify.
    
    Returns:
    
    Unique ID of the instance group to modify.
  - instanceCount
```
public final Integer instanceCount()
```
    Target size for the instance group.
    
    Returns:
    
    Target size for the instance group.
  - hasEc2InstanceIdsToTerminate
```
public final boolean hasEc2InstanceIdsToTerminate()
```
    For responses, this returns true if the service returned a value for the EC2InstanceIdsToTerminate 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.
  - ec2InstanceIdsToTerminate
```
public final List<String> ec2InstanceIdsToTerminate()
```
    The Amazon EC2 InstanceIds to terminate. After you terminate the instances, the instance group will not return to its original requested size.
    
    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 hasEc2InstanceIdsToTerminate() method.
    
    Returns:
    
    The Amazon EC2 InstanceIds to terminate. After you terminate the instances, the instance group will not return to its original requested size.
  - shrinkPolicy
```
public final ShrinkPolicy shrinkPolicy()
```
    Policy for customizing shrink operations.
    
    Returns:
    
    Policy for customizing shrink operations.
  - reconfigurationType
```
public final ReconfigurationType reconfigurationType()
```
    Type of reconfiguration requested. Valid values are MERGE and OVERWRITE.
    
    If the service returns an enum value that is not available in the current SDK version, reconfigurationType will return ReconfigurationType.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from reconfigurationTypeAsString().
    
    Returns:
    
    Type of reconfiguration requested. Valid values are MERGE and OVERWRITE.
    
    See Also:
    
    ReconfigurationType
  - reconfigurationTypeAsString
```
public final String reconfigurationTypeAsString()
```
    Type of reconfiguration requested. Valid values are MERGE and OVERWRITE.
    
    If the service returns an enum value that is not available in the current SDK version, reconfigurationType will return ReconfigurationType.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from reconfigurationTypeAsString().
    
    Returns:
    
    Type of reconfiguration requested. Valid values are MERGE and OVERWRITE.

  - hasConfigurations
```
public final boolean hasConfigurations()
```
    For responses, this returns true if the service returned a value for the Configurations 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.
  - configurations
```
public final List<Configuration> configurations()
```
    A list of new or modified configurations to apply for an instance group.
    
    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 hasConfigurations() method.
    
    Returns:
    
    A list of new or modified configurations to apply for an instance group.
