  - instanceFleetType
```
public InstanceFleetType instanceFleetType()
```
    The node type of the instance fleet. For example MASTER, CORE, or TASK.
    
    If the service returns an enum value that is not available in the current SDK version, instanceFleetType will return InstanceFleetType.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from instanceFleetTypeAsString().
    
    Returns:
    
    The node type of the instance fleet. For example MASTER, CORE, or TASK.
    
    See Also:
    
    InstanceFleetType
  - instanceFleetTypeAsString
```

  - instanceStatesAsStrings
```
public List<String> instanceStatesAsStrings()
```
    A list of instance states that will filter the instances returned with this request.

    Specified by:
    
    toBuilder in interface ToCopyableBuilder<ListInstancesRequest.Builder,ListInstancesRequest>
    
    Specified by:
    
    toBuilder in class EmrRequest
    
    Returns:
    
    a builder for type T

```
  - hashCode
```
public int hashCode()
```
    Overrides:
    
    hashCode in class AwsRequest
  - equals
```
public boolean equals(Object obj)
```
    Overrides:
    
    equals in class AwsRequest
  - equalsBySdkFields
```
public boolean equalsBySdkFields(Object obj)
```
    Description copied from interface: SdkPojo
    
    Indicates whether some other object is "equal to" this one by SDK fields. An SDK field is a modeled, non-inherited field in an SdkPojo class, and is generated based on a service model.
    If an SdkPojo class does not have any inherited fields, equalsBySdkFields and equals are essentially the same.
    
    Specified by:
    
    equalsBySdkFields in interface SdkPojo
    
    Parameters:
    
    obj - the object to be compared with
    
    Returns:
    
    true if the other object equals to this object by sdk fields, false otherwise.
  - toString
```
public String toString()
```
    Returns a string representation of this object. This is useful for testing and debugging. Sensitive data will be redacted from this string using a placeholder value.
    
    Overrides:
    
    toString in class Object
  - getValueForField
```
public <T> Optional<T> getValueForField(String fieldName,
                                        Class<T> clazz)
```
    Description copied from class: SdkRequest
    
    Used to retrieve the value of a field from any class that extends SdkRequest. The field name specified should match the member name from the corresponding service-2.json model specified in the codegen-resources folder for a given service. The class specifies what class to cast the returned value to. If the returned value is also a modeled class, the SdkRequest.getValueForField(String, Class) method will again be available.
    
    Overrides:
    
    getValueForField in class SdkRequest
    
    Parameters:
    
    fieldName - The name of the member to be retrieved.
    
    clazz - The class to cast the returned object to.
    
    Returns:
    
    Optional containing the casted return value
  - sdkFields
```
public List<SdkField<?>> sdkFields()
```
    Specified by:
    
    sdkFields in interface SdkPojo
    
    Returns:
    
    List of SdkField in this POJO. May be empty list but should never be null.
