The Esri TinNodeEnumerator component.
TinNodeEnumerator is a non-creatable object. References to non-creatable objects must be obtained through other objects.
The TinNodeEnumerator object is used for iterative TinNode processing on TINs. For example, to return all nodes within the interpolation zone (domain) of a TIN or the nodes of a TinPolyline. TinFilters, like TinValueFilter and TinDataElementFilter are used to control which nodes are passed back by the enumerator. Custom, application specific, filters can be used as well.
The TinNodeEnumerator object isn't co-creatable. Other functions are used to create it. Tin, TinPolyline, and TinPolygon objects can create and return TinNodeEnumerators.
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.
