Provides access to members that create, add, and hand out topologies.
The ITopologyContainer2 interface should be used to create topologies that will contain at least one feature class that is Z aware. The ITopologyContainer2::CreateTopologyEx method allows the specification of a Z cluster tolerance, which indicates which Z clustering model will be used; Building or Terrain.

The ITopologyContainer2 interface can be used to manage and create topologies within a feature dataset. If your intention is to simply browse for the set of topologies in a feature dataset, it is not necessary to open the feature dataset and call the methods on ITopologyContainer. The IFeatureDatasetName2::TopologyNames method can be used to efficiently obtain this information. Careful consideration should be given to specifying the parameters when creating a topology. Once the topology is built, none of the parameters can be modified. In order to change properties such as the Z cluster tolerance, the topology must be deleted and rebuilt with the new parameters.
