public class RegionInstanceGroupManagerClient
extends Object
implements com.google.api.gax.core.BackgroundResource
```
Service Description: Creates and runs virtual machines on Google Cloud Platform.
This class provides the ability to make remote calls to the backing service through method calls that map to API methods. Sample code to get started:
```
 
 try (RegionInstanceGroupManagerClient regionInstanceGroupManagerClient = RegionInstanceGroupManagerClient.create()) {
   ProjectRegionInstanceGroupManagerName instanceGroupManager = ProjectRegionInstanceGroupManagerName.of("[PROJECT]", "[REGION]", "[INSTANCE_GROUP_MANAGER]");
   RegionInstanceGroupManagersAbandonInstancesRequest regionInstanceGroupManagersAbandonInstancesRequestResource = RegionInstanceGroupManagersAbandonInstancesRequest.newBuilder().build();
   Operation response = regionInstanceGroupManagerClient.abandonInstancesRegionInstanceGroupManager(instanceGroupManager, regionInstanceGroupManagersAbandonInstancesRequestResource);
 }
 
 
```
Note: close() needs to be called on the regionInstanceGroupManagerClient object to clean up resources such as threads. In the example above, try-with-resources is used, which automatically calls close().
The surface of this class includes several types of Java methods for each of the API's methods:
1. A "flattened" method. With this type of method, the fields of the request type have been converted into function parameters. It may be the case that not all fields are available as parameters, and not every API method will have a flattened method entry point.
2. A "request object" method. This type of method only takes one parameter, a request object, which must be constructed before the call. Not every API method will have a request object method.
3. A "callable" method. This type of method takes no parameters and returns an immutable API callable object, which can be used to initiate calls to the service.
See the individual methods for example code.
Many parameters require resource names to be formatted in a particular way. To assist with these names, this class includes a format method for each type of name, and additionally a parse method to extract the individual identifiers contained within names that are returned.
This class can be customized by passing in a custom instance of RegionInstanceGroupManagerSettings to create(). For example:
To customize credentials:
```
 
 RegionInstanceGroupManagerSettings regionInstanceGroupManagerSettings =
     RegionInstanceGroupManagerSettings.newBuilder()
         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
         .build();
 RegionInstanceGroupManagerClient regionInstanceGroupManagerClient =
     RegionInstanceGroupManagerClient.create(regionInstanceGroupManagerSettings);
 
 
```
To customize the endpoint:
```
 
 RegionInstanceGroupManagerSettings regionInstanceGroupManagerSettings =
     RegionInstanceGroupManagerSettings.newBuilder().setEndpoint(myEndpoint).build();
 RegionInstanceGroupManagerClient regionInstanceGroupManagerClient =
     RegionInstanceGroupManagerClient.create(regionInstanceGroupManagerSettings);
 
 
```

```
Flags the specified instances to be immediately removed from the managed instance group. Abandoning an instance does not delete the instance, but it does remove the instance from any target pools that are applied by the managed instance group. This method reduces the targetSize of the managed instance group by the number of instances that you abandon. This operation is marked as DONE when the action is scheduled even if the instances have not yet been removed from the group. You must separately verify the status of the abandoning action with the listmanagedinstances method.
If the group is part of a backend service that has enabled connection draining, it can take up to 60 seconds after the connection draining duration has elapsed before the VM instance is removed or deleted.
You can specify a maximum of 1000 instances with this method per request.
Sample code:
```
 try (RegionInstanceGroupManagerClient regionInstanceGroupManagerClient = RegionInstanceGroupManagerClient.create()) {
   ProjectRegionInstanceGroupManagerName instanceGroupManager = ProjectRegionInstanceGroupManagerName.of("[PROJECT]", "[REGION]", "[INSTANCE_GROUP_MANAGER]");
   RegionInstanceGroupManagersAbandonInstancesRequest regionInstanceGroupManagersAbandonInstancesRequestResource = RegionInstanceGroupManagersAbandonInstancesRequest.newBuilder().build();
   Operation response = regionInstanceGroupManagerClient.abandonInstancesRegionInstanceGroupManager(instanceGroupManager, regionInstanceGroupManagersAbandonInstancesRequestResource);
 }
 
```
Parameters:

instanceGroupManager - Name of the managed instance group.

If the group is part of a backend service that has enabled connection draining, it can take up to 60 seconds after the connection draining duration has elapsed before the VM instance is removed or deleted.

Parameters:

size - Number of instances that should exist in this instance group manager.

instanceGroupManager - Name of the managed instance group.

Throws:

com.google.api.gax.rpc.ApiException - if the remote call fails

@BetaApi
public final Operation resizeRegionInstanceGroupManager(Integer size,
                                                                 String instanceGroupManager)
```
Changes the intended size of the managed instance group. If you increase the size, the group creates new instances using the current instance template. If you decrease the size, the group deletes one or more instances.
The resize operation is marked DONE if the resize request is successful. The underlying actions take additional time. You must separately verify the status of the creating or deleting actions with the listmanagedinstances method.
If the group is part of a backend service that has enabled connection draining, it can take up to 60 seconds after the connection draining duration has elapsed before the VM instance is removed or deleted.
Sample code:
```
 try (RegionInstanceGroupManagerClient regionInstanceGroupManagerClient = RegionInstanceGroupManagerClient.create()) {
   Integer size = 0;
   ProjectRegionInstanceGroupManagerName instanceGroupManager = ProjectRegionInstanceGroupManagerName.of("[PROJECT]", "[REGION]", "[INSTANCE_GROUP_MANAGER]");
   Operation response = regionInstanceGroupManagerClient.resizeRegionInstanceGroupManager(size, instanceGroupManager.toString());
 }
 
```
Parameters:

size - Number of instances that should exist in this instance group manager.

instanceGroupManager - Name of the managed instance group.

Throws:

com.google.api.gax.rpc.ApiException - if the remote call fails
