Any lower case characters present in S will be folded - -- to their upper case equivalent except for character literals. If S - -- consists of entirely blanks then Constraint_Error is raised. - -- - -- Note: if S is the null string, F is set to S'First, L to S'Last - - procedure Scan_Sign - (Str : String; - Ptr : access Integer; - Max : Integer; - Minus : out Boolean; - Start : out Positive); - -- The Str, Ptr, Max parameters are as for the scan routines (Str is the - -- string to be scanned starting at Ptr.all, and Max is the index of the - -- last character in the string). Scan_Sign first scans out any initial - -- blanks, raising Constraint_Error if the field is all blank. It then - -- checks for and skips an initial plus or minus, requiring a non-blank - -- character to follow (Constraint_Error is raised if plus or minus - -- appears at the end of the string or with a following blank). Minus is - -- set True if a minus sign was skipped, and False otherwise. On exit - -- Ptr.all points to the character after the sign, or to the first - -- non-blank character if no sign is present. Start is set to the point - -- to the first non-blank character (sign or digit after it). - -- - -- Note: if Str is null, i.e. if Max is less than Ptr, then this is a - -- special case of an all-blank string, and Ptr is unchanged, and hence - -- is greater than Max as required in this case. Constraint_Error is - -- also raised in this case. - - procedure Scan_Plus_Sign - (Str : String; - Ptr : access Integer; - Max : Integer; - Start : out Positive); - -- Same as Scan_Sign, but allows only plus, not minus. - -- This is used for modular types. - - function Scan_Exponent - (Str : String; - Ptr : access Integer; - Max : Integer; - Real : Boolean := False) return Integer; - -- Called to scan a possible exponent. Str, Ptr, Max are as described above - -- for Scan_Sign. If Ptr.all < Max and Str (Ptr.all) = 'E' or 'e', then an - -- exponent is scanned out, with the exponent value returned in Exp, and - -- Ptr.all updated to point past the exponent. If the exponent field is - -- incorrectly formed or not present, then Ptr.all is unchanged, and the - -- returned exponent value is zero. Real indicates whether a minus sign - -- is permitted (True = permitted). Very large exponents are handled by - -- returning a suitable large value. If the base is zero, then any value - -- is allowed, and otherwise the large value will either cause underflow - -- or overflow during the scaling process which is fine. - - procedure Scan_Trailing_Blanks (Str : String; P : Positive); - -- Checks that the remainder of the field Str (P .. Str'Last) is all - -- blanks. Raises Constraint_Error if a non-blank character is found. - - procedure Scan_Underscore - (Str : String; - P : in out Natural; - Ptr : access Integer; - Max : Integer; - Ext : Boolean); - -- Called if an underscore is encountered while scanning digits. Str (P) - -- contains the underscore. Ptr it the pointer to be returned to the - -- ultimate caller of the scan routine, Max is the maximum subscript in - -- Str, and Ext indicates if extended digits are allowed. In the case - -- where the underscore is invalid, Constraint_Error is raised with Ptr - -- set appropriately, otherwise control returns with P incremented past - -- the underscore. - -end System.Val_Util; |
