NAME

       KiokuDB::LiveObjects::TXNScope - Transaction scope.

VERSION

       version 0.57

SYNOPSIS

           $txn_scope = $live_objects->new_txn;

           $txn_scope->update_entries(@updated);

           $txn_scope->rollback;

DESCRIPTION

       This is an auxiliary class used by transaction scoping to roll back entries updated during
       a transaction when it is aborted.

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

ATTRIBUTES

           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.
