[jira] [Created] (UIMA-3097) Split JCasIterable into iterable and iterator parts

Richard Eckart de Castilho created UIMA-3097:
------------------------------------------------

             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.
