NAME

String::Parity - parity (odd/even/mark/space) handling functions

CONTENTS

SYNOPSIS



 use String::Parity;
 use String::Parity qw(:DEFAULT /show/);



DESCRIPTION

setEvenParity LIST Copies the elements of LIST to a new list and converts the new elements to strings of bytes with even parity. In array context returns the new list. In scalar context joins the elements of the new list into a single string and returns the string.
setOddParity LIST Like setEvenParity function, but converts to strings with odd parity.
setSpaceParity LIST Like setEvenParity function, but converts to strings with space (High bit cleared) parity.
setMarkParity LIST Like setEvenParity function, but converts to strings with mark (High bit set) parity.
EvenBytes LIST Returns the number of even parity bytes in the elements of LIST.
OddBytes LIST Returns the number of odd parity bytes in the elements of LIST.
SpaceBytes LIST Returns the number of space parity bytes in the elements of LIST.
MarkBytes LIST Returns the number of mark parity bytes in the elements of LIST.
isEvenParity LIST Returns TRUE if the LIST contains no byte with odd parity, FALSE otherwise.
isOddParity LIST Returns TRUE if the LIST contains no byte with even parity, FALSE otherwise.
isSpaceParity LIST Returns TRUE if the LIST contains no byte with mark parity, FALSE otherwise.
isMarkParity LIST Returns TRUE if the LIST contains no byte with space parity, FALSE otherwise.
showParity LIST Like setEvenParity function, but converts bytes with even parity to ’e’ and other bytes to ’o’. The function showParity must be imported by a specialised import list.
showMarkSpace LIST Like setEvenParity function, but converts bytes with space parity to ’s’ and other bytes to ’m’. The function showMarkSpace must be imported by a specialised import list.

NOTES

Don’t use this module unless you have to communicate with some old device or protocol. Please make your application 8 bit clean and use the internationally standardised ISO-8859-1 character set.

SEE ALSO

I don’t know of any other modules that provide similar functionality. If you do, please let me know so I can update this section.
