Osservazioni

Event chronicle rules maintain the data in event chronicle tables. Each event chronicle has a name, an action, and an action time-out, and a parent event class.

Esempio

The following example shows how to create an event chronicle rule that simply copies all events to a chronicle:

// Define the event chronicle rule
EventChronicleRule ec1Rule = 
    new EventChronicleRule(flightEvents, 
    "FlightEventChronicleRule");
ec1Rule.Action = "INSERT MyAppSchema.FlightEventChronicle " + 
    " (LeavingFrom, GoingTo, Price) " + 
    " SELECT LeavingFrom, GoingTo, Price " + 
    " FROM MyAppSchema.FlightEvents;";
ec1Rule.ActionTimeout = new TimeSpan(0, 1, 20);
flightEvents.EventChronicleRule = ec1Rule;

' Define the event chronicle rule
Dim ec1Rule As EventChronicleRule = _
    New EventChronicleRule(flightEvents, _
        "FlightEventChronicleRule")
ec1Rule.Action = _
    "INSERT MyAppSchema.FlightEventChronicle " + _
    " (LeavingFrom, GoingTo, Price) " + _
    " SELECT LeavingFrom, GoingTo, Price " + _
    " FROM MyAppSchema.FlightEvents;"
ec1Rule.ActionTimeout = New TimeSpan(0, 1, 20)
flightEvents.EventChronicleRule = ec1Rule
