Create and route an event of this type to update a data item by specifying a sequence of new filed values. If the update does not succeed, a response is provided by a DataViewItemException event.
Syntax description
msgId
Optional field for a message ID that applications can use to identify responses.
dvName
Unique name of this item's associated DataView definition.
dvItemId
Service-generated ID (see DataViewItem) of the item to be updated.
timeStamp
Timestamp for this update (seconds since epoch). If the value given is -1.0, the service will populate it using correlator currentTime. Note that the default value of the field is 0.0, which prevents trend graphs from updating.
fieldValues
A sequence of new field values in string form. The ith value in this sequence is the value that you want as the value of the ith field specified in the fieldNames sequence of the associated DataView definition.
extraParams
Optional field that future implementations may use.
