-- updating rrd_update to use accessor fks
-
-Plan:
-
-Encapsulating access to the RRD files through
-special accessor functions which provide
-access to the datastructures within the
-RRDfiles.
-
-pseudo code by Jake
-
-For example, here is a current code block from rrd_update.c:
-
- for (i=0;i<rrd.stat_head->ds_cnt;i++) {
- if(isnan(pdp_new[i]))
- rrd.pdp_prep[i].scratch[PDP_unkn_sec_cnt].u_cnt += interval;
- else
- rrd.pdp_prep[i].scratch[PDP_val].u_val+= pdp_new[i];
- }
-
-This could read:
-
- for (i=0 ; i < getDSCount(&rrd) ;i++) {
- if(isnan(pdp_new[i])) {
- temp = getPDPParam(&rrd, i, PDP_unkn_sec_cnt);
- temp.u_cnt += interval;
- setPDPParam(&rrd, i, PDP_unkn_sec_cnt, temp);
- } else {
- temp = getPDPParam(&rrd, i, PDP_val);
- temp.u_val += pdp_new[i];
- setPDPParam(&rrd, i, PDP_val, temp);
- }
- }
