Subject [jira] [Commented] (UIMA-1524) JFSIndexRepository should be enhanced with new generic methods
Date Mon, 12 Sep 2016 21:50:20 GMT

    [ https://issues.apache.org/jira/browse/UIMA-1524?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15485398#comment-15485398

Richard Eckart de Castilho commented on UIMA-1524:
--------------------------------------------------

How about using the "established" vocabulary from uimaFIT (J)CasUtil? E.g. coveredBy(), covering(),
etc. at least when there are equivalents?

Do we need to to use a no-args method called stream or could we be more flexible and maybe
add methods directly to CAS instead of having to go through indexes, e.g.

{code}
int filteredTextSum = cas.select(Token.class)  //create a stream over the standard annotation
index for the Token type
       .reverse()    
       .boundedBy(boundingAnnotation) // like subiterator
       .boundsRespectTypePriorities(true) // default is false
       .strict(true)  // default is false; same as nonOverlappingFSs(true)
       .mapToInt(f -> f.getEnd() - f.getBegin()) // get the length of the covered text
       .sum(); // add all of these</code>
{code}

or

{code}
int filteredTextSum = cas.select("myindex", Token.class)  // create a stream over the  index
"myindex" for the Token type
       .reverse()    
       .boundedBy(boundingAnnotation) // like subiterator
       .boundsRespectTypePriorities(true) // default is false
       .strict(true)  // default is false; same as nonOverlappingFSs(true)
       .mapToInt(f -> f.getEnd() - f.getBegin()) // get the length of the covered text
       .sum(); // add all of these</code>
{code}

> Existing methods should be overloaded with an additional Class argument to specify the
exact return type. This changes make down casting of returned objects unnecessary.
