             Summary: Split JCasIterable into iterable and iterator parts
                 Key: UIMA-3097
                 URL: https://issues.apache.org/jira/browse/UIMA-3097
             Project: UIMA
          Issue Type: Improvement
          Components: uimaFIT
            Reporter: Richard Eckart de Castilho
            Assignee: Richard Eckart de Castilho
             Fix For: 2.0.0uimaFIT


The JCasIterable is an Iterable and an Iterator at the same time. The 
iterator() method returns just "this". This goes against the expectation that 
an Iterable should return a fresh iterator when iterator() is called.

JCasIterable should therefore be split. The JCasIterable should only be 
creatable with descriptions.

Calling iterator should create a new JCasIterator which then is based on 
concrete reader and AE instances.
