CoClasses that implement IFeatureClassContainer

CoClasses and Classes Description
FeatureDataset Esri Feature Dataset object.
GeometricNetwork Esri Geometric Network object.
NetworkDataset A container for querying information about a network dataset.
Topology Esri Topology object.


The IFeatureClassContainer interface provides access to feature classes.  For feature datasets, it can be seen as an alternative to the functionality available on other objects.  Also, since IFeatureClassContainer is implemented by IGeometricNetwork and ITopology, it can be used to return the feature classes which participate in those types of datasets. 

There is no guarentee on the order that the feature classes will be returned for IFeatureClassContainer::Classes.

Opening a feature class that participates in a topology or geometric network will also open all other feature classes participating in the topology or geometric network in memory.
