marc::charset::table
MARC::Charset::Table(3pm) User Contributed Perl Documentation MARC::Charset::Table(3pm)
NAME
MARC::Charset::Table - character mapping db
SYNOPSIS
use MARC::Charset::Table;
use MARC::Charset::Constants qw(:all);
# create the table object
my $table = MARC::Charset::Table->new();
# get a code using the marc8 character set code and the character
my $code = $table->lookup_by_marc8(CYRILLIC_BASIC, 'K');
# get a code using the utf8 value
$code = $table->lookup_by_utf8(chr(0x043A));
DESCRIPTION
MARC::Charset::Table is a wrapper around the character mapping database, which is implemented as a tied hash on disk. This database gets
generated by Makefile.PL on installation of MARC::Charset using MARC::Charset::Compiler.
The database is essentially a key/value mapping where a key is a MARC-8 character set code + a MARC-8 character, or an integer representing
the UCS code point. These keys map to a serialized MARC::Charset::Code object.
new()
The consturctor.
add_code()
Add a MARC::Charset::Code to the table.
get_code()
Retrieve a code using a hash key.
lookup_by_marc8()
Looks up MARC::Charset::Code entry using a character set code and a MARC-8 value.
use MARC::Charset::Constants qw(HEBREW);
$code = $table->lookup_by_marc8(HEBREW, chr(0x60));
lookup_by_utf8()
Looks up a MARC::Charset::Code object using a utf8 value.
db()
Returns a reference to a tied character database. MARC::Charset::Table wraps access to the db, but you can get at it if you want.
db_path()
Returns the path to the character encoding database. Can be called statically too:
print MARC::Charset::Table->db_path();
brand_new()
An alternate constructor which removes the existing database and starts afresh. Be careful with this one, it's really only used on
MARC::Charset installation.
