Container for the parameters to the ModifyInstanceGroups operation.

ModifyInstanceGroups modifies the number of nodes and configuration settings of an instance group. The input parameters include the new target instance count for the group and the instance group ID. The call will either succeed or fail atomically.

 
 public class ModifyInstanceGroupsRequest extends AmazonWebServiceRequest implements SerializableCloneable {

    
Instance groups to change.
 
Default constructor for a new ModifyInstanceGroupsRequest object. Callers should use the setter or fluent setter (with...) methods to initialize this object after creating it.
 
     public ModifyInstanceGroupsRequest() {}
    
    
Constructs a new ModifyInstanceGroupsRequest object. Callers should use the setter or fluent setter (with...) methods to initialize any additional object members.

Parameters:
instanceGroups Instance groups to change.
 
         setInstanceGroups(instanceGroups);
     }

    
Instance groups to change.

Returns:
Instance groups to change.
 
         if ( == null) {

Instance groups to change.

NOTE: This method appends the values to the existing list (if any). Use setInstanceGroups(java.util.Collection) or withInstanceGroups(java.util.Collection) if you want to override the existing values.

Returns a reference to this object so that method calls can be chained together.

Parameters:
instanceGroups Instance groups to change.
Returns:
A reference to this updated object so that method calls can be chained together.
