Examples of redis.clients.jedis.Transaction

redis.clients.jedis.Transaction
Transaction is nearly identical to Pipeline, only differences are the multi/discard behaviors

            if (!conn.sismember(inventory, itemId)){
                conn.unwatch();
                return false;
            }


            Transaction trans = conn.multi();
            trans.zadd("market:", price, item);
            trans.srem(inventory, itemId);
            List<Object> results = trans.exec();
            // null response indicates that the transaction was aborted due to
            // the watched key changing.
            if (results == null){
                continue;
