Interface TopologySource

public interface TopologySource
Marker interface for objects that can produce `StormTopology` objects.

If a `topology-source` class implements the `getTopology()` method, Flux will call that method. Otherwise, it will introspect the given class and look for a similar method that produces a `StormTopology` instance.

Note that it is not strictly necessary for a class to implement this interface. If a class defines a method with a similar signature, Flux should be able to find and invoke it.
