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();
