Method Details

setContent

public void setContent(String content,
 boolean autoComplete,
 boolean appendOptionalChecksum)
                throws BarcodeException

Sets the EAN-8 number to be encoded in the barcode.

The number must be either 8 (with check digit) or 7 (without check digit) in length.

• If the number contains 8 digits, the 8th digit is checked to see if it is a valid check digit according to the EAN-8 standard. If the check digit is invalid, a BarcodeException is thrown.
• If the number contains 7 digits and autoComplete is set to true, the method calculates the missing check digit and appends it to the specified number. If autoComplete is set to false, a BarcodeException is thrown.

Specified by:

setContent in class Barcode

Parameters:

content - the EAN-8 number to be encoded in the barcode

autoComplete - whether to automatically calculate and append a check digit if it is missing

appendOptionalChecksum - has no function, as EAN-8 uses a fixed check digit which is not optional

Throws:

BarcodeException - if the content is empty, contains non-numeric characters, is of invalid length, or has an invalid check digit
