Method Detail

getParameters

IArray getParameters()
                     throws IOException,
                            AutomationException

Array of parameters for this network attribute.

Remarks

This property provides access to the IArray interface that holds the collection of NetworkAttributeParameter objects that are available for this NetworkAttribute.

Product Availability

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

Returns:

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

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

setParametersByRef

void setParametersByRef(IArray parameters)
                        throws IOException,
                               AutomationException

Array of parameters for this network attribute.

Remarks

This property provides access to the IArray interface that holds the collection of NetworkAttributeParameter objects that are available for this NetworkAttribute.

Product Availability

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

Parameters:

parameters - A reference to a com.esri.arcgis.system.IArray (in)

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

refresh

void refresh()
             throws IOException,
                    AutomationException

Refresh the network evaluators assigned to this network attribute.

Remarks

Calling Refresh propogates the call to INetworkEvaluator2::Refresh on the attribute's underlying network evaluators that implement INetworkEvaluator2. This gives the evaluator an opportunity to update its state based on current data or parameter values. This method is called by the network analyst solvers after setting INetworkAttribute2::Parameters prior to performing the solve operation.

Product Availability

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

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

isUseByDefault

boolean isUseByDefault()
                       throws IOException,
                              AutomationException

Indicates if this network attribute is to be used by default.

Remarks

If the UseByDefault property is set to True for a NetworkAttribute, the network attribute will automatically be set as an option (e.g., impedance, restriction, hierarchy) when a new network analysis layer is created in ArcMap.

Product Availability

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

Returns:

The useByDefault

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

setUseByDefault

void setUseByDefault(boolean useByDefault)
                     throws IOException,
                            AutomationException

Indicates if this network attribute is to be used by default.

Product Availability

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

Parameters:

useByDefault - The useByDefault (in)

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.
