SYNOPSIS

$txn_scope = $live_objects->new_txn;
$txn_scope->update_entries(@updated);
$txn_scope->rollback;

DESCRIPTION

This is used internally in ``txn_do'' in KiokuDB and should not need to be used directly.

ATTRIBUTES

entries

An ordered log of updated entries.

METHODS

update_entries

Called by ``update_entries'' in KiokuDB::LiveObjects. Adds entries to "entries".

rollback

Calls "KiokuDB::LiveObjects/rollback_entries" with all the recorded entries.
