Provides access to members that create, add, and hand out topologies.

When To Use
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.

Remarks
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.
