string::parity

Parity(3)						User Contributed Perl Documentation						 Parity(3)

NAME

       String::Parity, setEvenParity, setOddParity, setSpaceParity, setMarkParity, isEvenParity, isOddParity isSpaceParity, isMarkParity, Even-
       Bytes, OddBytes, SpaceBytes, MarkBytes, showParity, showMarkSpace - 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.

       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
