Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Method Summary

boolean	applies(INAContext nAContext) Indicates if the symbolizer applies to the analysis context.
INALayer	createLayer(INAContext nAContext) Creates a new analysis layer.
int	getPriority() The priority is used to determine the best symbolizer to symbolize a network analysis layer.
boolean	updateLayer(INALayer nALayer) Updates an existing analysis layer.

Method Detail

applies

boolean applies(INAContext nAContext)
                throws IOException,
                       AutomationException

Indicates if the symbolizer applies to the analysis context.

Remarks

Applies returns true or false if the symbolizer applies to the solver context specified by NAContext.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Parameters:

nAContext - A reference to a com.esri.arcgis.networkanalyst.INAContext (in)

Returns:

The flag

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

getPriority

int getPriority()
                throws IOException,
                       AutomationException

The priority is used to determine the best symbolizer to symbolize a network analysis layer. If multiple symbolizers apply to the network analysis layer, the one with the largest numeric value for priority is used to create and update the network analysis laye?Ÿ??&

Remarks

get_Priority returns the priority of the NASymbolizer. This allows a custom symbolizer with higher priority to be registered with NASymbolizer to be used in place of the default symbolizer for a particular NAContext.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Returns:

The priority

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

createLayer

INALayer createLayer(INAContext nAContext)
                     throws IOException,
                            AutomationException

Creates a new analysis layer.

Remarks

CreateLayer creates the symbology for an NALayer's sublayers. For example, the stops for a route solver are symbolized with located, unlocated, or error symbols.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Parameters:

nAContext - A reference to a com.esri.arcgis.networkanalyst.INAContext (in)

Returns:

A reference to a com.esri.arcgis.networkanalyst.INALayer

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

updateLayer

boolean updateLayer(INALayer nALayer)
                    throws IOException,
                           AutomationException

Updates an existing analysis layer.

Remarks

UpdateLayer updates the existing renderer such as when a service area solver is run again with a different set of breaks.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Parameters:

nALayer - A reference to a com.esri.arcgis.networkanalyst.INALayer (in)

Returns:

The updated

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.
