INASolver Interface

Provides access to the common interface for all network solvers.

Product Availability

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

Members

	Name	Description
	Bind	Re-associate the solver with the given network dataset and its schema.
	CanAccumulateAttributes	Indicates if the solver supports using accumulate network attributes.
	CanUseHierarchy	Indicates if the solver supports using a hierarchy network attribute.
	ClassDefinitions	The inputs and outputs defined by the solver.
	CreateContext	Creates the analysis context for the solver.
	CreateLayer	Makes a new network analysis layer for the solver context.
	DisplayName	The display name of the solver.
	Name	The name of the solver.
	Properties	The properties for the solver.
	Solve	Perform the network analysis and construct results.
	UpdateContext	Update the analysis context for the solver.
	UpdateLayer	Updates the layer and indicates if the layer was updated.

Classes that implement INASolver

Classes	Description
NAClosestFacilitySolver	Performs closest facility analysis.
NALocationAllocationSolver	Solves various location-allocation problem types
NAODCostMatrixSolver	Performs origin-destination matrix analysis.
NARouteSolver	Performs shortest path and tour analysis.
NAServiceAreaSolver	Performs service area analysis.
NAVRPSolver	Performs VRP network analysis.

Remarks

The INASolver interface is a common interface used by all of the network solvers. It can be used to access some of the standard properties from the solver. It is also used to create NAContext and NALayer objects and to perform the actual network analysis.
