IStringArray getRequiredFieldNames() throws java.io.IOException, AutomationException
RequiredFieldNames returns the field names that the evaluator requires in order to correctly evaluate the row. This property is used to minimize the data that is returned by the query to the database by only returning the required fields. Return a NULL pointer if you want it to include all the field names in the query.
java.io.IOException
- If there are interop problems.
AutomationException
- If the ArcObject component throws an exception.void refresh() throws java.io.IOException, AutomationException
The Refresh method is an opportunity to update any internal state within the evaluator based on changes to parameters, dynamic data feeds, etc. The Refresh method is called on every evaluator assigned to a network attribute when INetworkAttribute2::Refresh() is called. For example, this is called internally during a solve operation after setting the network attribute parameters and prior to performing the actual solve.
java.io.IOException
- If there are interop problems.
AutomationException
- If the ArcObject component throws an exception.
