Remarks

Fields returns the fields on the NAClass.

Product Availability

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

Returns:

A reference to a com.esri.arcgis.geodatabase.IFields

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

getFieldType

int getFieldType(String fieldName)
                 throws IOException,
                        AutomationException

The field type for a network analyst class field.

Product Availability

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

Parameters:

fieldName - The fieldName (in)

Returns:

The naFieldType

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

getCandidateFieldNames

IStringArray getCandidateFieldNames(String fieldName)
                                    throws IOException,
                                           AutomationException

The field names that will be used by default for the network analyst class.

Product Availability

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

Parameters:

fieldName - The fieldName (in)

Returns:

A reference to a com.esri.arcgis.system.IStringArray

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

isHasLocationFields

boolean isHasLocationFields()
                            throws IOException,
                                   AutomationException

Indicates if the class has location fields.

Remarks

HasLocationFields returns true if the NAClass has the 4 fields (SourceID, SourceOID, PosAlong, and SideOfEdge) that are necessary to represent network locations.

Product Availability

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

Returns:

The hasLocationFields

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

getLowerBound

int getLowerBound()
                  throws IOException,
                         AutomationException

The minimum number of objects required in the class by the solver to perform analysis.

Remarks

LowerBound specifies the minimum number of NALocationObjects that are required by the solver to perform analysis.

For example, an NARouteSolver requires at least 2 stops. This means that the LowerBound property of the Stop's NAClassDefinition would be 2.

Product Availability

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

Returns:

The lowerBound

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

Product Availability

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

Returns:

The isOutput

Throws:
