Examples of org.apache.uima.fit.pipeline.JCasIterator

org.apache.uima.fit.pipeline.JCasIterator
A class implementing iteration over a the documents of a collection. Each element in the Iterable is a JCas containing a single document. The documents have been loaded by the CollectionReader and processed by the AnalysisEngine (if any).
