getByKeyf_t and getByKeyf_T

($type, $value) = $session->getByKeyf_t( $object, $table,
     [ $keytype, $keyvalue ], $freshness )

Identical to getByKey_t() but takes the “freshness” of the entry into account. The section “$freshness” on page 73 provides additional information.

 ($type, $data) = $session->getByKeyf_t(
   "GA_CompoundDriver::Bridge-Generic-Driver",
   "drivers", [ "INT", 10 ], 120 );
