IArray getParameters() throws IOException, AutomationException
This property provides access to the IArray interface that holds the collection of NetworkAttributeParameter objects that are available for this NetworkAttribute.
IOException
- If there are interop problems.
AutomationException
- If the ArcObject component throws an exception.void setParametersByRef(IArray parameters) throws IOException, AutomationException
This property provides access to the IArray interface that holds the collection of NetworkAttributeParameter objects that are available for this NetworkAttribute.
parameters
- A reference to a com.esri.arcgis.system.IArray (in)
IOException
- If there are interop problems.
AutomationException
- If the ArcObject component throws an exception.void refresh() throws IOException, AutomationException
Calling Refresh propogates the call to INetworkEvaluator2::Refresh on the attribute's underlying network evaluators that implement INetworkEvaluator2. This gives the evaluator an opportunity to update its state based on current data or parameter values. This method is called by the network analyst solvers after setting INetworkAttribute2::Parameters prior to performing the solve operation.
When solving against live traffic data, Refresh puts the NetworkAttribute in a state to check for a dynamic traffic file (DTF) on the next time-based attribute query. That first query will decide which DTF will apply to all subsequent solves, until the next call to Refresh.
IOException
- If there are interop problems.
AutomationException
- If the ArcObject component throws an exception.boolean isUseByDefault() throws IOException, AutomationException
If the UseByDefault property is set to True for a NetworkAttribute, the network attribute will automatically be set as an option (e.g., impedance, restriction, hierarchy) when a new network analysis layer is created in ArcMap.
IOException
- If there are interop problems.
AutomationException
- If the ArcObject component throws an exception.void setUseByDefault(boolean useByDefault) throws IOException, AutomationException
useByDefault
- The useByDefault (in)
IOException
- If there are interop problems.
AutomationException
- If the ArcObject component throws an exception.
