org.apache.uima.analysis_engine.metadata.FixedFlow
A FixedFlow is a simple type of {@link FlowConstraints} that specifies thecomplete flow as a fixed sequence.
Each element in the sequence is specified as a String identifier. The FixedFlow object does not assign any particular meaning to these Strings - it is the user of the FixedFlow object that must understand how to map them to AnalysisEngines themselves.
