```
public class SimpleFlow
extends java.lang.Object
implements Flow, org.springframework.beans.factory.InitializingBean
```
A Flow that branches conditionally depending on the exit status of the last State. The input parameters are the state transitions (in no particular order). The start state name can be specified explicitly (and must exist in the set of transitions), or computed from the existing transitions, if unambiguous.
