This class is a step handler that does nothing.
This class is provided as a convenience for users who are only interested in the final state of an integration and not in the intermediate steps. Its handleStep method does nothing.
Since this class has no internal state, it is implemented using the Singleton design pattern. This means that only one instance is ever created, which can be retrieved using the getInstance method. This explains why there is no public constructor.
