Character Set Declarations

type Character_Set is private;

Representation for a set of character values:

type Character_Range is record
   Low  : Character;
   High : Character;
end record;

Represents Character range Low .. High

type Character_Ranges is array (Positive range <>) of Character_Range;

function To_Set    (Ranges : in Character_Ranges) return Character_Set;

function To_Set    (Span   : in Character_Range)  return Character_Set;

function To_Ranges (Set    : in Character_Set)    return Character_Ranges;

Operations on Character Sets

function "="   (Left, Right : in Character_Set) return Boolean;

function "not" (Right       : in Character_Set) return Character_Set;

function "and" (Left, Right : in Character_Set) return Character_Set;

function "or"  (Left, Right : in Character_Set) return Character_Set;

function "xor" (Left, Right : in Character_Set) return Character_Set;

function "-"   (Left, Right : in Character_Set) return Character_Set;

function Is_In
  (Element : in Character;
   Set     : in Character_Set)
   return    Boolean;

function Is_Subset
  (Elements : in Character_Set;
   Set      : in Character_Set)
   return     Boolean;

function "<="
  (Left  : in Character_Set;
   Right : in Character_Set)
   return  Boolean
renames Is_Subset;

subtype Character_Sequence is String;

Alternative representation for a set of character values

function To_Set (Sequence  : in Character_Sequence) return Character_Set;

function To_Set (Singleton : in Character)          return Character_Set;

function To_Sequence (Set : in Character_Set) return Character_Sequence;

Character Mapping Declarations

type Character_Mapping is private;

Representation for a character to character mapping:

function Value
  (Map     : in Character_Mapping;
   Element : in Character)
   return    Character;

function To_Mapping
  (From, To : in Character_Sequence)
   return     Character_Mapping;

function To_Domain
  (Map  : in Character_Mapping)
   return Character_Sequence;

function To_Range
  (Map  : in Character_Mapping)
   return Character_Sequence;

type Character_Mapping_Function is
   access function (From : in Character) return Character;
