Examples of FinalStep

org.apache.uima.flow.FinalStep
Indicates that a CAS has finished being processed by the aggregate. After returning a FinalStep, the {@link Flow#next()} method will not be called again for this CAS.
If the CAS was passed in as an input to the aggregate's process method, then the aggregate's processing is completed and ownership of this CAS is returned to the caller.
If the CAS was generated internally to this aggregate (by a CAS Multiplier that is part of this aggregate), then it will either be output from the aggregate or it will be dropped. A CAS can only be output if the aggregate's metadata includes declares the operational property outputsNewCASes == true. (see {@link org.apache.uima.resource.metadata.OperationalProperties#getOutputsNewCASes()}).
By default, if the aggregate's metadata declares outputsNewCASes == true, then all CASes generated internal to the aggregate are output. However, by passing true to the {@link #FinalStep(boolean)} constructor, the Flow Controller can force a particular CAS to bedropped. This allows the Flow Controller to output some CASes but not others.
It is not permitted to drop a CAS that was passed as input to the AnalysisEngine, and using FinalStep(true) for such a CAS is an error.
