NAME
Lux::IO - A Perl Interface to Lux IO
SYNOPSIS
use Lux::IO;
use Lux::IO::Btree;
my $bt = Lux::IO::Btree->new(Lux::IO::CLUSTER);
$bt->open('test', Lux::DB_CREAT);
$bt->put('key', 'value', Lux::IO::OVERWRITE); #=> true
$bt->get('key'); #=> 'value'
$bt->del('key'); #=> true
$bt->get('key'); #-> false
$bt->close;
DESCRIPTION
Lux IO is a yet another database manager. Lux::IO provides a Perl interface to it. You must note that it supports only BTree-based database so far, though Lux IO supports also hash-based database.
METHODS
new ( $index_type )
my $bt = Lux::IO::Btree->new(Lux::IO::CLUSTER);
Creates and returns a new Lux::IO::Btree object. $insert_type
can be one of the types below:
over 4
* Lux::IO::CLUSTER
* Lux::IO::NONCLUSTER
back
open ( $filename, $oflags )
$bt->open($filename, Lux::DB_CREAT);
Opens a database specified by $filename

can be one of or a combination of the flags below:
over 4
* Lux::DB_RDONLY
* Lux::DB_RDWR
* Lux::DB_CREAT
* Lux::DB_TRUNC
back
close ()
$bt->close();
Closes the database.
get ( $key )
$bt->get($key);
Retrieves a value which is correspondent to the $key
from the database.
put ( $key, $value, $insert_mode )
$bt->put($key, $value, Lux::IO::OVERWRITE);
Stores the key-value pair into the database. $insert_mode
can be one of the modes below:
