IJunctionConnectivityRule Interface

Provides access to members that supply information about, modify and manage junction-edge connectivity rules. Note: the IJunctionConnectivityRule interface has been superseded by IJunctionConnectivityRule2. Please consider using the more recent version.

Product Availability

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

Description

When To Use

The IJunctionConnectivityRule is the main interface for creating and getting information about a junction connectivity rule. Use this interface to create a new junction connectivity rule between subtypes in an edge network feature class and a junction network feature class. This interface also allows you to specify valid cardinality ranges for the rule.

Members

	Name	Description
	Category	The name associated with the validation rule.
	EdgeClassID	The ID of the NetworkEdge FeatureClass.
	EdgeMaximumCardinality	The maxnimum cardinality value of the NetworkEdge FeatureClass.
	EdgeMinimumCardinality	The minimum cardinality value of the NetworkEdge FeatureClass.
	EdgeSubtypeCode	The subtype value of the NetworkEdge FeatureClass.
	Helpstring	The helpstring associated with the validation rule.
	ID	The ID of the validation rule.
	JunctionClassID	The ID of the NetworkJunction FeatureClass.
	JunctionMaximumCardinality	The maximum cardinality value of the NetworkJunction FeatureClass.
	JunctionMinimumCardinality	The minimum cardinality value of the NetworkJunction FeatureClass.
	JunctionSubtypeCode	The subtype value of the NetworkJunction FeatureClass.
	Type	The type associated with the validation rule.

Inherited Interfaces

JunctionConnectivityRule	Esri Junction-Edge NetworkConnectivity rule object.

Remarks

IJunctionConnectivityRule interface allows a user to constrain the type of network junction features that may be connected to one another, by specifying edge cardinalities and junction cardinalities. This allows a user to more effectively manage junctions in a network and maintain dabase integrity by not allowing invalid junction features.
