NAME

KiokuDB::LiveObjects::TXNScope - Transaction scope.

SYNOPSIS

    $txn_scope = $live_objects->new_txn;

DESCRIPTION

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

METHODS

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