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.
