org.apache.uima.analysis_engine.metadata.FlowConstraints
A FlowConstraints object represents constraints on the order of execution of delegate Analysis Engines within an aggregate Analysis Engine. In the most constrained case, this is a fixed flow.
This interface implements no methods for flow constraint specification. It serves as a common superclass for different ways of specifying flow constraints.
Flow constraints must refer to delegate AnalysisEngines; the FlowConstraints object refers to these AEs using String identifiers. The FlowConstraints object does not assign any particular meaning to these Strings - it is the user of the FlowConstraints object that must understand how to map them to the AnalysisEngines themselves. It may be desirable to remap these identifiers; FlowConstraints implementations must support this via the {@link #remapIDs(Map)} method.
