NAME
IO::Journal::Transaction - Perl interface to IO::Journal transactions
VERSION
Version 0.2 ($Id: Transaction.pm 8239 2009-07-26 03:28:55Z FREQUENCY@cpan.org $)
DESCRIPTION
This module provides the facilities for handling IO::Journal transactions. Operations can be added to the transaction object via the exposed interface; they can then be either saved to file (commit) or simply discarded (rollback).
SYNOPSIS
my $trans = $journal->begin_transaction();
$trans->write("Hello ");
$trans->write("World\n");
$trans->commit(); # may die
# File either contains "Hello World\n" or nothing
# Transactions can be rolled back even after committing! (But only if we
# have a current handle to the transaction)
$trans->rollback();METHODS
