- values
  
  public static EmptyTuple[] values()
  
  Returns an array containing the constants of this enum type, in the order they are declared.
  
  Returns:
  
  an array containing the constants of this enum type, in the order they are declared
- valueOf
  
  public static EmptyTuple 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
- toString
  
  public String toString()
  
  Overrides:
  
  toString in class Enum<EmptyTuple>
- canonicalize
  
  public EmptyTuple canonicalize(@NotNull UnaryOperator<Object> canonicalizer)
  
  Description copied from interface: CanonicalizableTuple
  
  Canonicalize this tuple.
  
  Specified by:
  
  canonicalize in interface CanonicalizableTuple<EmptyTuple>
  
  Parameters:
  
  canonicalizer - The canonicalization operator to use on each object element.
  
  Returns:
  
  This tuple if already canonical, else a new, canonical tuple of the same type
