Hi all,
In my Edge code (using WS-EMS and Lua Script Resource), I am using code similar to the following to store values to an infotable I have created like that.
dataShapes.GasLogEntry( { name = "Timestamp", baseType = "INTEGER" }, { name = "Channel", baseType = "INTEGER" }, { name = "GasReading", baseType = "NUMBER" } ) ... tw_mutex.lock() local gasDS = DataShape.GasLogEntry:clone() tw_mutex.unlock() local gasIT = tw_infotable.createInfoTable(gasDS) |
and then the following to add rows to that infotable
local success, err = gasIT:addRow({ Timestamp = GasLogTime, Channel = 100, --channelIterator, GasReading = varGasReading }) |
However, I cannot seem to find a way of clearing rows inserted into the infotable. As I use this infotable to send accumulated data (within this infotable) on-demand to the platform, then clearing and re-using it multiple times, what I use right now to empty my infotable and re-initialise it is breaking the link to the infotable object by pointing the variable previously bound to it to a freshly instantiated infotable each time, assuming the garbage collector will get rid of the redundant object. However, I am suspecting I may be running out of memory gradually as I find the machine running the EMS and LSR has crashed after several hours (during which I have emptied and re-used the same table about a couple of hundred times).
So my questions are these:
1. Is there a way to go through the infotable and remove rows one by one? Is there something like i.e. gasIT:removeRow? I ahven't found anything in the documentation.
2. Even if I left my code as-is, wouldn't the garbage collector tidy up the leftovers? It's really frustrating to have the whole EMS/LSR processes going down and taking the machine down with them (crashing).
I would really appreciate any help, thanks in advance.
Marios
