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.

    Map delegates = desc.getDelegateAnalysisEngineSpecifiersWithImports();
    delegates.put("Pear1", impPear1);
    delegates.put("Pear2", impPear2);


    // add sequence - fixed flow
    FixedFlow fixedFlow = UIMAFramework.getResourceSpecifierFactory().createFixedFlow();
    fixedFlow.setFixedFlow(new String[] { "Pear1", "Pear2" });


    // add analysis engine meta data
    AnalysisEngineMetaData md = desc.getAnalysisEngineMetaData();
    md.setName("PEAR aggregate");
    md.setDescription("combines tow PEARs");
