Remarks

The NALocatorLocationFieldsAgent object uses existing source ID, OID and position information to find network locations.  This is much faster than the spatial searching that the NALocatorFeatureAgent uses.

When you solve a network analysis problem, you can export, for example, the stops with this information.  If your network locations are not changing often (e.g., your restaurants don't move around), then using network location fields and this locator agent is the most efficient way to store and restore network locations.
