    The number of nodes in the cluster that are active (i.e., capable of serving requests).
    
    Returns:
    
    The number of nodes in the cluster that are active (i.e., capable of serving requests).
  - nodeType
```
public final String nodeType()
```
    The node type for the nodes in the cluster. (All nodes in a DAX cluster are of the same type.)
    
    Returns:
    
    The node type for the nodes in the cluster. (All nodes in a DAX cluster are of the same type.)
  - status
```
public final String status()
```
    The current status of the cluster.
    
    Returns:
    
    The current status of the cluster.
  - clusterDiscoveryEndpoint
```
public final Endpoint clusterDiscoveryEndpoint()
```
    The endpoint for this DAX cluster, consisting of a DNS name, a port number, and a URL. Applications should use the URL to configure the DAX client to find their cluster.
    
    Returns:
    
    The endpoint for this DAX cluster, consisting of a DNS name, a port number, and a URL. Applications should use the URL to configure the DAX client to find their cluster.
  - hasNodeIdsToRemove
```
public final boolean hasNodeIdsToRemove()
```
    For responses, this returns true if the service returned a value for the NodeIdsToRemove 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.
  - nodeIdsToRemove
```
public final List<String> nodeIdsToRemove()
```
    A list of nodes to be removed from the cluster.
    
    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 hasNodeIdsToRemove() method.
    
    Returns:
    
    A list of nodes to be removed from the cluster.
  - hasNodes
```
public final boolean hasNodes()
```
    For responses, this returns true if the service returned a value for the Nodes 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.
  - nodes
```
public final List<Node> nodes()
```
    A list of nodes that are currently in the cluster.
    
    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 hasNodes() method.
    
    Returns:
    
    A list of nodes that are currently in the cluster.
  - preferredMaintenanceWindow
```
public final String preferredMaintenanceWindow()
```
    A range of time when maintenance of DAX cluster software will be performed. For example: sun:01:00-sun:09:00. Cluster maintenance normally takes less than 30 minutes, and is performed automatically within the maintenance window.
    
    Returns:
    
    A range of time when maintenance of DAX cluster software will be performed. For example: sun:01:00-sun:09:00. Cluster maintenance normally takes less than 30 minutes, and is performed automatically within the maintenance window.
  - notificationConfiguration
```
public final NotificationConfiguration notificationConfiguration()
```
    Describes a notification topic and its status. Notification topics are used for publishing DAX events to subscribers using Amazon Simple Notification Service (SNS).
    
    Returns:
    
    Describes a notification topic and its status. Notification topics are used for publishing DAX events to subscribers using Amazon Simple Notification Service (SNS).
  - subnetGroup
```
public final String subnetGroup()
```
    The subnet group where the DAX cluster is running.
    
    Returns:
    
    The subnet group where the DAX cluster is running.
  - hasSecurityGroups
```
public final boolean hasSecurityGroups()
```
    For responses, this returns true if the service returned a value for the SecurityGroups 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.
  - securityGroups
```
public final List<SecurityGroupMembership> securityGroups()
```
    A list of security groups, and the status of each, for the nodes in the cluster.
    
    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 hasSecurityGroups() method.
    
    Returns:
    
    A list of security groups, and the status of each, for the nodes in the cluster.
  - iamRoleArn

    The description of the server-side encryption status on the specified DAX cluster.
    
    Returns:
    
    The description of the server-side encryption status on the specified DAX cluster.
  - clusterEndpointEncryptionType
```
public final ClusterEndpointEncryptionType clusterEndpointEncryptionType()
```
    The type of encryption supported by the cluster's endpoint. Values are:
    
    NONE for no encryption
    
    TLS for Transport Layer Security
    
    If the service returns an enum value that is not available in the current SDK version, clusterEndpointEncryptionType will return ClusterEndpointEncryptionType.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from clusterEndpointEncryptionTypeAsString().
