MARC::File - Base class for files of MARC records
use MARC::File::USMARC;
my $file = MARC::File::USMARC->in( $filename );
while ( my $marc = $file->next() ) {
# Do something
}
$file->close();
undef $file;
None.
in()Opens a file for import. Ordinarily you will use MARC::File::USMARC
or MARC::File::MicroLIF to do this.
my $file = MARC::File::USMARC->in( 'file.marc' );
Returns a MARC::File object, or undef on failure. If you
encountered an error the error message will be stored in
$MARC::File::ERROR.
Optionally you can also pass in a filehandle, and MARC::File.
will ``do the right thing''.
my $handle = IO::File->new( 'gunzip -c file.marc.gz |' );
my $file = MARC::File::USMARC->in( $handle );
Reads the next record from the file handle passed in.
The $filter_func is a reference to a filtering function. Currently,
only USMARC records support this. See the MARC::File::USMARC manpage's decode()
function for details.
Returns a MARC::Record reference, or undef on error.
skip()Skips over the next record in the file. Same as next(),
without the overhead of parsing a record you're going to throw away
anyway.
Returns 1 or undef.
warnings()Simlilar to the methods in the MARC::Record manpage and the MARC::Batch manpage,
warnings() will return any warnings that have accumulated while
processing this file; and as a side-effect will clear the warnings buffer.
out() method
