Summary : Perl extension for International Standard Serial Numbers
Description :
* new($issn)
The constructor accepts a scalar representing the ISSN.
The string representing the ISSN may contain characters other than [0-9xX],
although these will be removed in the internal representation. The
resulting string must look like an ISSN - the first seven characters must
be digits and the eighth character must be a digit, 'x', or 'X'.
The string passed as the ISSN need not be a valid ISSN as long as it
superficially looks like one. This allows one to use the 'fix_checksum'
method.
One should check the validity of the ISSN with 'is_valid()' rather than
relying on the return value of the constructor.
If all one wants to do is check the validity of an ISSN, one can skip the
object-oriented interface and use the c function which
is exportable on demand.
If the constructor decides it can't create an object, it returns undef. It
may do this if the string passed as the ISSN can't be munged to the
internal format.
* $obj->checksum
Return the ISSN checksum.
* $obj->as_string
Return the ISSN as a string.
A terminating 'x' is changed to 'X'.
* $obj->is_valid
Returns 1 if the checksum is valid.
Returns 0 if the ISSN does not pass the checksum test. The constructor
accepts invalid ISSN's so that they might be fixed with 'fix_checksum'.
* $obj->fix_checksum
Replace the eighth character with the checksum the corresponds to the
previous seven digits. This does not guarantee that the ISSN corresponds to
the product one thinks it does, or that the ISSN corresponds to any product
at all. It only produces a string that passes the checksum routine. If the
ISSN passed to the constructor was invalid, the error might have been in
any of the other nine positions.
