- Enum Constant Detail
  - USER
```
public static final ListOrder USER
```
    The list was sorted by a user. The criteria the user used are not specified.
  - SYSTEM
```
public static final ListOrder SYSTEM
```
    The list was sorted by the system. The criteria the user used are not specified; define additional codes to specify a particular order (or use other defined codes).
  - EVENTDATE
```
public static final ListOrder EVENTDATE
```
    The list is sorted by the data of the event. This can be used when the list has items which are dates with past or future events.
  - ENTRYDATE
```
public static final ListOrder ENTRYDATE
```
    The list is sorted by the date the item was added to the list. Note that the date added to the list is not explicit in the list itself.
  - PRIORITY
```
public static final ListOrder PRIORITY
```
    The list is sorted by priority. The exact method in which priority has been determined is not specified.
  - ALPHABETIC
```
public static final ListOrder ALPHABETIC
```
    The list is sorted alphabetically by an unspecified property of the items in the list.
  - CATEGORY
```
public static final ListOrder CATEGORY
```
    The list is sorted categorically by an unspecified property of the items in the list.
  - PATIENT
```
public static final ListOrder PATIENT
```
    The list is sorted by patient, with items for each patient grouped together.
  - NULL
```
public static final ListOrder NULL
```
    added to help the parsers
- Method Detail
  - values
```
public static ListOrder[] values()
```
    Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
    for (ListOrder c : ListOrder.values()) System.out.println(c);
    Returns:
    
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static ListOrder valueOf(String name)
```
    Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
    
    Parameters:
    
    name - the name of the enum constant to be returned.
    
    Returns:
    
    the enum constant with the specified name
    
    Throws:
    
    IllegalArgumentException - if this enum type has no constant with the specified name
    
    NullPointerException - if the argument is null
  - fromCode
```
public static ListOrder fromCode(String codeString)
                          throws org.hl7.fhir.exceptions.FHIRException
```
    Throws:
    
    org.hl7.fhir.exceptions.FHIRException
  - toCode
```
public String toCode()
```
  - getSystem
```
public String getSystem()
```
  - getDefinition
```
public String getDefinition()
```
  - getDisplay
```
public String getDisplay()
```
