A container for defining to the NetSolver which network elements have barriers.
Product Availability
Description
The NetElementBarriers object contains references to barriers on a geometric network.
Supported Platforms
Extended Error Information
Use the ISupportErrorInfo method InterfaceSupportsErrorInfo to determine if the object supports extended error information. If the object supports extended error info, VC++ developers should use the OLE/COM IErrorInfo interface to access the ErrorInfo object. Visual Basic developers should use the global error object Err to retrieve this extended error information.
Interfaces
| Interfaces | Description |
|---|---|
| INetElementBarriersGEN | Provides access to members that specify a set of barriers by EIDs for the TraceFlowSolver object. |
| ISupportErrorInfo | Indicates whether a specific interface can return Automation error objects. |
Remarks
A NetElementBarriers object is used to specify element barriers for the TraceFlowSolver object. Because NetElementBarriers objects are co-creatable, you can use this class to specify barriers using code. Alternatively, by calling INetworkAnalysisExtBarriers::CreateElementBarriers, you can create NetElementBarriers objects that represent all the edge or junction barriers that were placed on the current network using the Utility Network Analyst toolbar.
