    values
    +
```
public static CreateMode[] 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 (CreateMode c : CreateMode.values())
+    System.out.println(c);
+
```
    +
    Returns:
    an array containing the constants of this enum type, in +the order they are declared

  + + + +
  - +
    valueOf
    +
```
public static CreateMode 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
