NAME

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

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.
