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. $oflags 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:
