DatabaseTableAgent.ReadRow

• 2 minutes to read

Scripting events called on the ReadRow method on the IDatabaseTableAgent service agent.

BeforeReadRow

    static void BeforeReadRow(
       String  tableName,
       Int32  id,
       ref object  eventState
      );

Executes before the service method is invoked. The return value is not calculated yet, so this method can't affect the result. It can store some state in the eventState parameter, that is passed to the After and AfterAsync methods in this service call. Event state is not preserved between different service calls. It is set to null at the start of each service call.

AfterReadRow

    static void AfterReadRow(
       String  tableName,
       Int32  id,
       ref TableRecord  returnValue,
       ref object  eventState
      );

Executes after the service method has been invoked. The service waits for this method to complete before returning the result to the caller. The return value has been set. The script may modify the return value by altering the returnValue parameter. Any state you set in the Before method is passed in through the eventState parameter.

AfterReadRowAsync

    static void AfterReadRowAsync(
       String  tableName,
       Int32  id,
       ref TableRecord  returnValue,
       ref object  eventState
      );

Executes after the service method is invoked, without waiting for the call to return. The service call is not blocked waiting for this method to complete. The async event handler cannot modify the return value of the service call. Any state you set in the Before method is passed in through the eventState parameter.
