public abstract class Step extends Object
Represents the next destination or destinations to which a CAS should be routed. AStep
is the output of theFlow.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 routedParallelStep
- 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.
