IJunctionFeatureSource.AddClassConnectivityGroup Method

Adds a connectivity group in which this junction feature source participates.

Public Sub AddClassConnectivityGroup ( _

Remarks

A JunctionFeatureSource can be assigned to connectivity group(s) in the network dataset in one of two ways:

• All features in the JunctionFeatureSource are assigned to the same connectivity group(s), or
• Features in the JunctionFeatureSource are assigned to connectivity group(s) based on their Subtype values.

If all features are assigned to the same connectivity group(s), then use the AddClassConnectivityGroup method to add a new connectivity group to the list of connectivity groups that this JunctionFeatureSource is assigned.

If features are assigned to connectivity group(s) based on their Subtype values, then the AddClassConnectivityGroup method is not used. See the AddSubtypeConnectivityGroup method.

If all features are assigned to the same connectivity group(s), then the UsesSubtypes property should be set to False. This means that the ClassConnectivityGroups and ClassConnectivityPolicy settings will apply to this JunctionFeatureSource.

If features are assigned to connectivity group(s) based on their Subtype values, then the UsesSubtypes property should be set to True. This means that the SubtypeConnectivityGroups and SubtypeConnectivityPolicy settings will apply to this JunctionFeatureSource.

Classes that implement IJunctionFeatureSource

Classes	Description
JunctionFeatureSource	A container for describing a network dataset source whose junction elements are derived from point feature geometry.

Remarks

The IJunctionFeatureSource interface is used to access the properties of the junction feature source, such as its connectivity groups and elevation field name.

To access the JunctionFeatureSource object for an existing network dataset source, use the Source, SourceByID, or SourceByName methods on the INetworkDataset interface.

The IJunctionFeatureSource interface is also used to define a new junction feature source. To create a new junction feature source, cocreate the JunctionFeatureSource object, specify its properties on both the INetworkSource and IJunctionFeatureSource interfaces, and pass the object to the INetworkBuild::AddSource method on the network dataset.
