INAClassLoader Interface

Provides access to populate network analysis classes in preparation for analysis. Note: the INAClassLoader interface has been superseded byINAClassLoader2. Please consider using the more recent version.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server. Requires Network Analyst Extension.

Members

Description
Read/write property FieldMap The field mapping definition.
Method Load Populate the network analysis class.
Read/write property Locator The locator to be used.
Read/write property NAClass The network analysis class.

CoClasses that implement INAClassLoader

CoClasses and Classes Description
NAClassLoader Loads a network class based on its field maps.

Remarks

INAClassLoader has been superseded by INAClassLoader2.
