All Known Implementing Classes:

Topology
```
public interface TopologyElement
```
Any element in a Topology. All elements in a Topology, including Topology itself, implement TopologyElement.
Some methods, typically those that create source streams, require a TopologyElement to identify the topology that the new element needs to be added to. Any other TStream or TWindow can be used as the TopologyElement passed to those methods, rather than having to pass the Topology reference all throughout the code that builds the topology.
