Interface INetElementBarriers

All Superinterfaces:

Serializable

All Known Subinterfaces:

INetElementBarriers2

All Known Implementing Classes:

INetElementBarriers2Proxy, INetElementBarriersProxy

public interface INetElementBarriers
extends Serializable

Provides access to members that specify a set of barriers for the TraceFlowSolver object.

Superseded By

INetElementBarriers2

Remarks

Sets of junction barriers and edge barriers should be created seperately.

When To Use

Use the INetElementBarriers interface to create a set of barriers to pass to the TraceFlowSolver object.

Barriers are stopping points affecting a trace. For example, a downed powerline can be a barrier that affects a trace. Barriers do not affect the flow through a network. If you want to change the flow through a stand-alone logical network you can disable individual elements using the INetAttributesEdit::SetDisabledState method. For geometric networks, set the INetworkFeature::Enabled property to False.

Product Availability

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

Not all members are callable from Java. Please use INetElementBarriersGEN instead.

Method Summary

int	getElementType() Type of network element on which the barriers are placed.
INetwork	getNetwork() Network on which the barrier set is placed.
void	setBarriers(int userClassID, int count, int[] userIDs) Specifies a set of network features to use as barriers.
void	setElementType(int elementType) Type of network element on which the barriers are placed.
void	setNetworkByRef(INetwork network) Network on which the barrier set is placed.
