Constructor Detail

Interleaved2Of5LogicImpl

public Interleaved2Of5LogicImpl(ChecksumMode mode,
                                boolean displayChecksum)

Main constructor.

Parameters:

mode - the checksum mode

displayChecksum - Controls whether to display checksum in the human-readable message

Method Detail

getChecksumMode

public ChecksumMode getChecksumMode()

Returns the current checksum mode

Returns:

the checksum mode

calcChecksum

public static char calcChecksum(java.lang.String msg,
                                int oddMultiplier,
                                int evenMultiplier)

Calculates the checksum for a message to be encoded as an Interleaved 2 of 5 barcode. The algorithm is a weighted modulo 10 scheme.

Parameters:

msg - message to calculate the check digit for

oddMultiplier - multiplier to be used for odd positions (usually 3 or 4)

evenMultiplier - multiplier to be used for even positions (usually 1 or 9)

Returns:

char the check digit

calcChecksum

public static char calcChecksum(java.lang.String msg)

Calculates the checksum for a message to be encoded as an Interleaved 2 of 5 barcode. The algorithm is a weighted modulo 10 scheme. This method uses the default specification (ITF-14, EAN-14, SSC-14, DUN14 and USPS).

Parameters:

msg - message to calculate the check digit for

Returns:

char the check digit

validateChecksum

public static boolean validateChecksum(java.lang.String msg)

Verifies the checksum for a message.

Parameters:

msg - message (check digit included)

Returns:

boolean True, if the checksum is correct

generateBarcodeLogic

public void generateBarcodeLogic(ClassicBarcodeLogicHandler logic,
                                 java.lang.String msg)

Generates the barcode logic.

Parameters:

logic - the logic handler to receive generated events

msg - the message to encode
