Subject [jira] [Commented] (ACCUMULO-1730) ColumnVisibility parse tree not always correct
Date Thu, 19 Sep 2013 19:11:57 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-1730?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13772177#comment-13772177
] 

John Stoneham commented on ACCUMULO-1730:
-----------------------------------------

It builds out the tree. There's only two children of the top node.

> Trying to do some transformations on visibility strings and running into issues working
with the parse tree:
> Clojure 1.5.1
> user=> (import [org.apache.accumulo.core.security ColumnVisibility])
> org.apache.accumulo.core.security.ColumnVisibility
> user=> (def vis (ColumnVisibility. "(W)|(U|V)"))
> #'user/vis
> user=> (.getTermStart (first (.getChildren (.getParseTree vis))))
> 1
> user=> (.getTermEnd (first (.getChildren (.getParseTree vis))))
> 2
> user=> (.getTermStart (second (.getChildren (.getParseTree vis))))
> 0
> user=> (.getTermEnd (second (.getChildren (.getParseTree vis))))
> 8
> Shouldn't those last two be 5 and 8?
