NAME
PICA::Writer::Base - Base class of PICA+ writers
SYNOPSIS
use PICA::Writer::Plain;
my $writer = PICA::Writer::Plain->new( $fh );
foreach my $record (@pica_records) {
$writer->write($record);
}
use PICA::Writer::Plus;
$writer = PICA::Writer::Plus->new( $fh );
...
use PICA::Writer::XML;
$writer = PICA::Writer::XML->new( $fh );
...
DESCRIPTION
This abstract base class of PICA+ writers should not be instantiated directly. Use one of the following subclasses instead:
METHODS
new( [ $fh | fh => $fh ] [ %options ] )
Create a new PICA writer, writing to STDOUT by default. The optional fh
argument can be a filename, a handle or any other blessed object with a print
method, e.g. IO::Handle.
PICA::Data also provides a functional constructor pica_writer
.
write ( @records )
Writes one or more records, given as hash with key 'record
' or as array reference with a list of fields, as described in PICA::Data.
write_record ( $record )
Writes one record.
end
Finishes writing by closing the file handle (unless writing to STDOUT).
OPTIONS
color
Syntax highlighting can be enabled for PICA::Writer::Plain and PICA::Writer::Plus using color names from Term::ANSIColor, e.g.
pica_writer('plain', color => {
tag => 'blue',
occurrence => 'magenta',
code => 'green',
value => 'white',
syntax => 'yellow',
})
SEE ALSO
See Catmandu::Exporter::PICA for usage of this module within the Catmandu framework (recommended).
Alternative (outdated) PICA+ writers had been implemented as PICA::Writer and PICA::XMLWriter included in the release of PICA::Record.
