hisWrite method
Write a set of history time-series data to the given point record.
The record must already be defined and must be properly tagged as a historized point. The timestamp timezone must exactly match the point's configured "tz" tag. If duplicate or out-of-order items are inserted then they must be gracefully merged.
Implementation
Future<HGrid> hisWrite(HRef id, List<HHisItem> items) {
HDict meta = HDictBuilder().add("id", id).toDict();
HGrid req = HGridBuilder.hisItemsToGrid(meta, items);
return call("hisWrite", req);
}
