DEFINITION MODULE WholeConv;
(* Low-level whole-number/string conversions *)
IMPORT
ConvTypes;
TYPE
ConvResults = ConvTypes.ConvResults;
(* strAllRight, strOutOfRange, strWrongFormat, strEmpty *)
PROCEDURE ScanInt (inputCh: CHAR; VAR chClass: ConvTypes.ScanClass;
VAR nextState: ConvTypes.ScanState);
(*
* Represents the start state of a finite state scanner for signed whole numbers -
* assigns class of inputCh to chClass and a procedure representing the next state
* to nextState.
*)
PROCEDURE FormatInt (str: ARRAY OF CHAR): ConvResults;
(*
* Returns the format of the string value for conversion to INTEGER.
*)
PROCEDURE ValueInt (str: ARRAY OF CHAR): INTEGER;
(*
* Returns the value corresponding to the signed whole number string value str if
* str is well-formed; otherwise raises the WholeConv exception.
*)
PROCEDURE LengthInt (int: INTEGER): CARDINAL;
(*
* Returns the number of characters in the string representation of int.
*)
PROCEDURE ScanCard (inputCh: CHAR; VAR chClass: ConvTypes.ScanClass;
VAR nextState: ConvTypes.ScanState);
(*
* Represents the start state of a finite state scanner for unsigned whole numbers -
* assigns class of inputCh to chClass and a procedure representing the next state
* to nextState.
*)
PROCEDURE FormatCard (str: ARRAY OF CHAR): ConvResults;
(*
* Returns the format of the string value for conversion to CARDINAL.
*)
PROCEDURE ValueCard (str: ARRAY OF CHAR): CARDINAL;
(*
* Returns the value corresponding to the unsigned whole number string value str if
* str is well-formed; otherwise raises the WholeConv exception.
*)
PROCEDURE LengthCard (card: CARDINAL): CARDINAL;
(*
* Returns the number of characters in the string representation of card.
*)
PROCEDURE IsWholeConvException (): BOOLEAN;
(*
* Returns TRUE if the current coroutine is in the exceptional execution state
* because of the raising of an exception in a routine from this module;
* otherwise returns FALSE.
