Method Detail
- values
```
public static Token[] 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 (Token c : Token.values())
    System.out.println(c);
```
  Returns:
  
  an array containing the constants of this enum type, in the order they are declared
- valueOf
```
public static Token valueOf(java.lang.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:
  
  java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
  
  java.lang.NullPointerException - if the argument is null
- arity
```
public static int arity(Token token)
```
  If the arity isn't always the same, this function returns -1
