MARC::File - Base class for files of MARC records
use MARC::File::USMARC; # If you have werid control fields... use MARC::Field; MARC::Field->allow_controlfield_tags('FMT', 'LDX'); my $file = MARC::File::USMARC->in( $filename ); while ( my $marc = $file->next() ) { # Do something } $file->close(); undef $file;
None.
Opens a file for import. Ordinarily you will use MARC::File::USMARC or MARC::File::MicroLIF to do this.
MARC::File::USMARC
MARC::File::MicroLIF
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.
MARC::File
undef
$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 MARC::File::USMARC's decode() function for details.
$filter_func
decode()
Returns a MARC::Record reference, or undef on error.
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.
next()
Returns 1 or undef.
Simlilar to the methods in MARC::Record and MARC::Batch, warnings() will return any warnings that have accumulated while processing this file; and as a side-effect will clear the warnings buffer.
warnings()
Closes the file, both from the object's point of view, and the actual file.
Writes a record to the output file. This method must be overridden in your subclass.
Decodes a record into a USMARC format. This method must be overridden in your subclass.
