Members

	Name	Description
	AddLocatorAgent	Add a locator agent.
	Bind	Re-associate the locators with the given network dataset and its schema.
	CacheRestrictedElements	The locator will examine the NAContext and its associated NASolver to build a cache of network elements that cannot be located on due to restrictions, barriers, etc. This method should be called before querying the locator whenever ExcludeRestrictedElements i
	CreateDefault	Make the default locators.
	ExcludeRestrictedElements	Indicates whether to exclude restricted portions of the network when locating points.
	FindClosestAmongAllAgents	Indicates if the closest location (only) should be returned.
	GeocodeLocation	The network location at the specified address. Honors side of street if the address locator does.
	LocatorAgent	The locator agent by index.
	LocatorAgentCount	The number of locator agents added.
	MaxSnapTolerance	The maximum distance that can be searched when expanding the snap tolerance. Has the same units as the snap tolerance.
	NetworkDataset	The associated network dataset.
	OutputSpatialReference	The spatial reference for points returned by the locator.
	QueryLocationByPoint	Use the locator agents to find a network location from a point.
	QueryLocationByPointEx	Use the locator agents to find a network location from a point and curb approach.
	QueryLocationByRow	Use the locator agents to find a network location from a row.
	QueryLocationByRowEx	Use the locator agents to find a network location from a row and curb approach.
	QueryLocationRangesByGeometry	Use the locator agents to find network location ranges from a geometry.
	QueryLocationRangesByRow	Use the locator agents to find a network location ranges from a row.
	QueryOffsetPoint	The point offset from a network location.
	QueryPoint	The point for a network location.
	RemoveLocatorAgent	Remove a locator agent by index.
	ReverseGeocodeLocation	The address of the network location. Honors side of street if the address locator does.
	SnapTolerance	The distance to search.
	SnapToleranceUnits	The units of the snap tolerance.

Inherited Interfaces

Classes that implement INALocator3

Remarks

The INALocator3 interface provides methods to specify settings and make calls to associated NALocatorAgents.

The interface also provides methods that allow the NALocator to automatically expand the snap tolerance when loading network locations.  The tolerance begins at the SnapTolerance and doubles each time until either a network location is found or the MaxSnapTolerance value is reached.

Generally, the NALocator should be retrieved from an NAContext.  However, if you do create an NALocator, or have added a new locator agent, then, before querying the NALocator, Bind should be called on the NALocator to set up the locator agents and associate it with the NetworkDataset.
