# Class Step

java.lang.Object
org.apache.uima.flow.Step

Direct Known Subclasses:
  `FinalStep`, `ParallelStep`, `SimpleStep`

public abstract class Step extends Object
Represents the next destination or destinations to which a CAS should be routed. A `Step` is the output of the `Flow.next()` method. A Flow should output an instance of a concrete class that extends Step. Currently, these are:

- `SimpleStep` - specifies a single AnalysisEngine to which the CAS should next be routed
- `ParallelStep` - specifies multiple AnalysisEngine to which the CAS should next be routed, where the relative order in which these Analysis Engines execute does not matter.
- `FinalStep` - indicates that there are no more destinations for this CAS.
