Class JObserve.PictureFormat

java.lang.Object
   |
   +----JObserve.PictureFormat

public class PictureFormat
extends Object

Implement PictureFormat from a now dead language (PL/I) This class consists solely of static functions. Result character arrays are the same size as the Pattern array and each character in the pattern controls the corresponding value in the output. E.g. "1234.56" with pattern "ZZ,ZZ,ZZ.ZZZ" => "00,12,34.560". Special characters in pattern:

'Z' - a digit from the input string; a blank is used if there are no more digits from the input string.
'9' - a digit from the input string; a '0' is used if there are no more digits from the input string.
'B' - a blank
'-' - a digit from the input string; the sign character in the least signifigant digit for which there is not an input digit.
'+' - like '-' but + sign is replaced by a blank
Anything else is written to the output string.

PictureFormat(String, String): Format a numeric string from a given pattern.
StringLeft(String, int): Reformat a string in a left justified, blank filled character array.
StringRight(String, int): Reformat a string in a right justified, blank filled character array.

PictureFormat

 public static char[] PictureFormat(String Digits,
                                    String Pattern)

Format a numeric string from a given pattern. Since Java string handling is so weak the string is returned in a character array.

Parameters:: String - The digits string (to be reformatted); String - The pattern, each character defines the contents of the corresponding position in the output,
Returns:: char[] The formatted string in a character array.

StringLeft

 public static char[] StringLeft(String Digits,
                                 int size)

Reformat a string in a left justified, blank filled character array. In the input string is longer than the output string, truncate on the right

Parameters:: String - The digits string (to be reformatted); int - The size of the output character array.
Returns:: char[] The formatted string in a character array.

StringRight

 public static char[] StringRight(String Digits,
                                  int size)

Reformat a string in a right justified, blank filled character array. In the input string is longer than the output string, truncate on the right

Parameters:: String - The digits string (to be reformatted); int - The size of the output character array.
