  - setEndpoint
```
public void setEndpoint(String endpoint)
```
    Description copied from interface: AmazonElasticFileSystem
    
    Overrides the default endpoint for this client ("https://elasticfilesystem.us-east-1.amazonaws.com"). Callers can use this method to control which AWS region they want to work with.
    Callers can pass in just the endpoint (ex: "elasticfilesystem.us-east-1.amazonaws.com") or a full URL, including the protocol (ex: "https://elasticfilesystem.us-east-1.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: https://docs.aws.amazon.com/sdk-for-java/v1/developer-guide/java-dg-region-selection.html#region-selection- choose-endpoint
    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.
    
    Specified by:
    
    setEndpoint in interface AmazonElasticFileSystem
    
    Parameters:
    
    endpoint - The endpoint (ex: "elasticfilesystem.us-east-1.amazonaws.com") or a full URL, including the protocol (ex: "https://elasticfilesystem.us-east-1.amazonaws.com") of the region specific AWS endpoint this client will communicate with.
  - setRegion
```
public void setRegion(Region region)
```
    Description copied from interface: AmazonElasticFileSystem
    
    An alternative to AmazonElasticFileSystem.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.
    
    Specified by:
    
    setRegion in interface AmazonElasticFileSystem
    
    Parameters:
    
    region - The region this client will communicate with. See Region.getRegion(com.amazonaws.regions.Regions) for accessing a given region. Must not be null and must be a region where the service is available.

  - createAccessPoint
```
public CreateAccessPointResult createAccessPoint(CreateAccessPointRequest request)
```
    Description copied from interface: AmazonElasticFileSystem
    
    Creates an EFS access point. An access point is an application-specific view into an EFS file system that applies an operating system user and group, and a file system path, to any file system request made through the access point. The operating system user and group override any identity information provided by the NFS client. The file system path is exposed as the access point's root directory. Applications using the access point can only access data in its own directory and below. To learn more, see Mounting a file system using EFS access points.
    
    This operation requires permissions for the elasticfilesystem:CreateAccessPoint action.
    
    Specified by:
    
    createAccessPoint in interface AmazonElasticFileSystem
    
    Returns:
    
    Result of the CreateAccessPoint operation returned by the service.

  - createFileSystem
```
public CreateFileSystemResult createFileSystem(CreateFileSystemRequest request)
```
    Description copied from interface: AmazonElasticFileSystem
    Creates a new, empty file system. The operation requires a creation token in the request that Amazon EFS uses to ensure idempotent creation (calling the operation with same creation token has no effect). If a file system does not currently exist that is owned by the caller's Amazon Web Services account with the specified creation token, this operation does the following:
    - Creates a new, empty file system. The file system will have an Amazon EFS assigned ID, and an initial lifecycle state creating.
    - Returns with the description of the created file system.
    Otherwise, this operation returns a FileSystemAlreadyExists error with the ID of the existing file system.
    
    For basic use cases, you can use a randomly generated UUID for the creation token.
    
    The idempotent operation allows you to retry a CreateFileSystem call without risk of creating an extra file system. This can happen when an initial call fails in a way that leaves it uncertain whether or not a file system was actually created. An example might be that a transport level timeout occurred or your connection was reset. As long as you use the same creation token, if the initial call had succeeded in creating a file system, the client can learn of its existence from the FileSystemAlreadyExists error.
    
    For more information, see Creating a file system in the Amazon EFS User Guide.
    
    The CreateFileSystem call returns while the file system's lifecycle state is still creating. You can check the file system creation status by calling the DescribeFileSystems operation, which among other things returns the file system state.
    
    This operation accepts an optional PerformanceMode parameter that you choose for your file system. We recommend generalPurpose performance mode for most file systems. File systems using the maxIO performance mode can scale to higher levels of aggregate throughput and operations per second with a tradeoff of slightly higher latencies for most file operations. The performance mode can't be changed after the file system has been created. For more information, see Amazon EFS performance modes.
    
    You can set the throughput mode for the file system using the ThroughputMode parameter.
    
    After the file system is fully created, Amazon EFS sets its lifecycle state to available, at which point you can create one or more mount targets for the file system in your VPC. For more information, see CreateMountTarget. You mount your Amazon EFS file system on an EC2 instances in your VPC by using the mount target. For more information, see Amazon EFS: How it Works.
    
    This operation requires permissions for the elasticfilesystem:CreateFileSystem action.
    Specified by:
    
    createFileSystem in interface AmazonElasticFileSystem
    
    Returns:
    
    Result of the CreateFileSystem operation returned by the service.

  - createMountTarget
```
public CreateMountTargetResult createMountTarget(CreateMountTargetRequest request)
```
    Description copied from interface: AmazonElasticFileSystem
    Creates a mount target for a file system. You can then mount the file system on EC2 instances by using the mount target.
    
    You can create one mount target in each Availability Zone in your VPC. All EC2 instances in a VPC within a given Availability Zone share a single mount target for a given file system. If you have multiple subnets in an Availability Zone, you create a mount target in one of the subnets. EC2 instances do not need to be in the same subnet as the mount target in order to access their file system.
    
    You can create only one mount target for an EFS file system using One Zone storage classes. You must create that mount target in the same Availability Zone in which the file system is located. Use the AvailabilityZoneName and AvailabiltyZoneId properties in the DescribeFileSystems response object to get this information. Use the subnetId associated with the file system's Availability Zone when creating the mount target.
    
    For more information, see Amazon EFS: How it Works.
    
    To create a mount target for a file system, the file system's lifecycle state must be available. For more information, see DescribeFileSystems.
    
    In the request, provide the following:
    - The file system ID for which you are creating the mount target.
    - A subnet ID, which determines the following:
      
      The VPC in which Amazon EFS creates the mount target
      
      The Availability Zone in which Amazon EFS creates the mount target
      
      The IP address range from which Amazon EFS selects the IP address of the mount target (if you don't specify an IP address in the request)
    After creating the mount target, Amazon EFS returns a response that includes, a MountTargetId and an IpAddress. You use this IP address when mounting the file system in an EC2 instance. You can also use the mount target's DNS name when mounting the file system. The EC2 instance on which you mount the file system by using the mount target can resolve the mount target's DNS name to its IP address. For more information, see How it Works: Implementation Overview.
    
    Note that you can create mount targets for a file system in only one VPC, and there can be only one mount target per Availability Zone. That is, if the file system already has one or more mount targets created for it, the subnet specified in the request to add another mount target must meet the following requirements:
    - Must belong to the same VPC as the subnets of the existing mount targets
    - Must not be in the same Availability Zone as any of the subnets of the existing mount targets
    If the request satisfies the requirements, Amazon EFS does the following:
    - Creates a new mount target in the specified subnet.
    - Also creates a new network interface in the subnet as follows:
      
      If the request provides an IpAddress, Amazon EFS assigns that IP address to the network interface. Otherwise, Amazon EFS assigns a free address in the subnet (in the same way that the Amazon EC2 CreateNetworkInterface call does when a request does not specify a primary private IP address).
      
      If the request provides SecurityGroups, this network interface is associated with those security groups. Otherwise, it belongs to the default security group for the subnet's VPC.
      
      Assigns the description Mount target fsmt-id for file system fs-id where fsmt-id is the mount target ID, and fs-id is the FileSystemId.
      
      Sets the requesterManaged property of the network interface to true, and the requesterId value to EFS.
      
      Each Amazon EFS mount target has one corresponding requester-managed EC2 network interface. After the network interface is created, Amazon EFS sets the NetworkInterfaceId field in the mount target's description to the network interface ID, and the IpAddress field to its address. If network interface creation fails, the entire CreateMountTarget operation fails.
    The CreateMountTarget call returns only after creating the network interface, but while the mount target state is still creating, you can check the mount target creation status by calling the DescribeMountTargets operation, which among other things returns the mount target state.
    
    We recommend that you create a mount target in each of the Availability Zones. There are cost considerations for using a file system in an Availability Zone through a mount target created in another Availability Zone. For more information, see Amazon EFS. In addition, by always using a mount target local to the instance's Availability Zone, you eliminate a partial failure scenario. If the Availability Zone in which your mount target is created goes down, then you can't access your file system through that mount target.

  - deleteFileSystem
```
public DeleteFileSystemResult deleteFileSystem(DeleteFileSystemRequest request)
```
    Description copied from interface: AmazonElasticFileSystem
    
    Deletes a file system, permanently severing access to its contents. Upon return, the file system no longer exists and you can't access any contents of the deleted file system.
    
    You can't delete a file system that is in use. That is, if the file system has any mount targets, you must first delete them. For more information, see DescribeMountTargets and DeleteMountTarget.
    
    The DeleteFileSystem call returns while the file system state is still deleting. You can check the file system deletion status by calling the DescribeFileSystems operation, which returns a list of file systems in your account. If you pass file system ID or creation token for the deleted file system, the DescribeFileSystems returns a 404 FileSystemNotFound error.
    
    This operation requires permissions for the elasticfilesystem:DeleteFileSystem action.

  - deleteMountTarget
```
public DeleteMountTargetResult deleteMountTarget(DeleteMountTargetRequest request)
```
    Description copied from interface: AmazonElasticFileSystem
    Deletes the specified mount target.
    
    This operation forcibly breaks any mounts of the file system by using the mount target that is being deleted, which might disrupt instances or applications using those mounts. To avoid applications getting cut off abruptly, you might consider unmounting any mounts of the mount target, if feasible. The operation also deletes the associated network interface. Uncommitted writes might be lost, but breaking a mount target using this operation does not corrupt the file system itself. The file system you created remains. You can mount an EC2 instance in your VPC by using another mount target.
    
    This operation requires permissions for the following action on the file system:
    - elasticfilesystem:DeleteMountTarget
    The DeleteMountTarget call returns while the mount target state is still deleting. You can check the mount target deletion by calling the DescribeMountTargets operation, which returns a list of mount target descriptions for the given file system.
    
    The operation also requires permissions for the following Amazon EC2 action on the mount target's network interface:
    - ec2:DeleteNetworkInterface
    Specified by:

  - describeFileSystems
```
public DescribeFileSystemsResult describeFileSystems(DescribeFileSystemsRequest request)
```
    Description copied from interface: AmazonElasticFileSystem
    
    Returns the description of a specific Amazon EFS file system if either the file system CreationToken or the FileSystemId is provided. Otherwise, it returns descriptions of all file systems owned by the caller's Amazon Web Services account in the Amazon Web Services Region of the endpoint that you're calling.
    
    When retrieving all file system descriptions, you can optionally specify the MaxItems parameter to limit the number of descriptions in a response. Currently, this number is automatically set to 10. If more file system descriptions remain, Amazon EFS returns a NextMarker, an opaque token, in the response. In this case, you should send a subsequent request with the Marker request parameter set to the value of NextMarker.
    
    To retrieve a list of your file system descriptions, this operation is used in an iterative process, where DescribeFileSystems is called first without the Marker and then the operation continues to call it with the Marker parameter set to the value of the NextMarker from the previous response until the response has no NextMarker.
    
    The order of file systems returned in the response of one DescribeFileSystems call and the order of file systems returned across the responses of a multi-call iteration is unspecified.

  - modifyMountTargetSecurityGroups
```
public ModifyMountTargetSecurityGroupsResult modifyMountTargetSecurityGroups(ModifyMountTargetSecurityGroupsRequest request)
```
    Description copied from interface: AmazonElasticFileSystem
    Modifies the set of security groups in effect for a mount target.
    
    When you create a mount target, Amazon EFS also creates a new network interface. For more information, see CreateMountTarget. This operation replaces the security groups in effect for the network interface associated with a mount target, with the SecurityGroups provided in the request. This operation requires that the network interface of the mount target has been created and the lifecycle state of the mount target is not deleted.
    
    The operation requires permissions for the following actions:
    - elasticfilesystem:ModifyMountTargetSecurityGroups action on the mount target's file system.
    - ec2:ModifyNetworkInterfaceAttribute action on the mount target's network interface.
    Specified by:
    
    modifyMountTargetSecurityGroups in interface AmazonElasticFileSystem
    
    Returns:
    
    Result of the ModifyMountTargetSecurityGroups operation returned by the service.

  - putAccountPreferences
```
public PutAccountPreferencesResult putAccountPreferences(PutAccountPreferencesRequest request)
```
    Description copied from interface: AmazonElasticFileSystem
    
    Use this operation to set the account preference in the current Amazon Web Services Region to use long 17 character (63 bit) or short 8 character (32 bit) resource IDs for new EFS file system and mount target resources. All existing resource IDs are not affected by any changes you make. You can set the ID preference during the opt-in period as EFS transitions to long resource IDs. For more information, see Managing Amazon EFS resource IDs.
    
    Starting in October, 2021, you will receive an error if you try to set the account preference to use the short 8 character format resource ID. Contact Amazon Web Services support if you receive an error and need to use short IDs for file system and mount target resources.
    
    Specified by:
    
    putAccountPreferences in interface AmazonElasticFileSystem
    
    Returns:
    
    Result of the PutAccountPreferences operation returned by the service.

  - putFileSystemPolicy
```
public PutFileSystemPolicyResult putFileSystemPolicy(PutFileSystemPolicyRequest request)
```
    Description copied from interface: AmazonElasticFileSystem
    
    Applies an Amazon EFS FileSystemPolicy to an Amazon EFS file system. A file system policy is an IAM resource-based policy and can contain multiple policy statements. A file system always has exactly one file system policy, which can be the default policy or an explicit policy set or updated using this API operation. EFS file system policies have a 20,000 character limit. When an explicit policy is set, it overrides the default policy. For more information about the default file system policy, see Default EFS File System Policy.
    
    EFS file system policies have a 20,000 character limit.
    
    This operation requires permissions for the elasticfilesystem:PutFileSystemPolicy action.
    
    Specified by:
    
    putFileSystemPolicy in interface AmazonElasticFileSystem
    
    Returns:
    
    Result of the PutFileSystemPolicy operation returned by the service.

  - putLifecycleConfiguration
```
public PutLifecycleConfigurationResult putLifecycleConfiguration(PutLifecycleConfigurationRequest request)
```
    Description copied from interface: AmazonElasticFileSystem
    Enables lifecycle management by creating a new LifecycleConfiguration object. A LifecycleConfiguration object defines when files in an Amazon EFS file system are automatically transitioned to the lower-cost EFS Infrequent Access (IA) storage class. To enable EFS Intelligent Tiering, set the value of TransitionToPrimaryStorageClass to AFTER_1_ACCESS. For more information, see EFS Lifecycle Management.
    
    Each Amazon EFS file system supports one lifecycle configuration, which applies to all files in the file system. If a LifecycleConfiguration object already exists for the specified file system, a PutLifecycleConfiguration call modifies the existing configuration. A PutLifecycleConfiguration call with an empty LifecyclePolicies array in the request body deletes any existing LifecycleConfiguration and turns off lifecycle management for the file system.
    
    In the request, specify the following:
    - The ID for the file system for which you are enabling, disabling, or modifying lifecycle management.
    - A LifecyclePolicies array of LifecyclePolicy objects that define when files are moved to the IA storage class. Amazon EFS requires that each LifecyclePolicy object have only have a single transition, so the LifecyclePolicies array needs to be structured with separate LifecyclePolicy objects. See the example requests in the following section for more information.
    This operation requires permissions for the elasticfilesystem:PutLifecycleConfiguration operation.
    
    To apply a LifecycleConfiguration object to an encrypted file system, you need the same Key Management Service permissions as when you created the encrypted file system.
    Specified by:
    
    putLifecycleConfiguration in interface AmazonElasticFileSystem
    
    Returns:
    
    Result of the PutLifecycleConfiguration operation returned by the service.

  - shutdown
```
public void shutdown()
```
    Description copied from interface: AmazonElasticFileSystem
    
    Shuts down this client object, releasing any resources that might be held open. This is an optional method, and callers are not expected to call it, but can if they want to explicitly release any open resources. Once a client has been shutdown, it should not be used to make any more requests.

  - getCachedResponseMetadata
```
public ResponseMetadata getCachedResponseMetadata(AmazonWebServiceRequest request)
```
    Description copied from interface: AmazonElasticFileSystem
    
    Returns additional metadata for a previously executed successful request, typically used for debugging issues where a service isn't acting as expected. This data isn't considered part of the result data returned by an operation, so it's available through this separate, diagnostic interface.
    Response metadata is only cached for a limited period of time, so if you need to access this extra diagnostic information for an executed request, you should use this method to retrieve it as soon as possible after executing a request.
    
    Specified by:
    
    getCachedResponseMetadata in interface AmazonElasticFileSystem
    
    Parameters:
    
    request - The originally executed request.
    
    Returns:
    
    The response metadata for the specified request, or null if none is available.
