---------------------------------------
This code
{noformat}
import org.apache.accumulo.core.security.ColumnVisibility;
import org.apache.accumulo.core.security.ColumnVisibility.Node;
public class Test {
static void printTree(int indent, String v, Node node) {
for (int i = 0; i < indent; i++)
System.out.print(' ');
System.out.println(node.getType() + " " + v.substring(node.getTermStart(),
node.getTermEnd()) + " " + node.getTermStart() + " " + node.getTermEnd());
for (Node child : node.getChildren()) {
printTree(indent + 1, v, child);
}
}
public static void main(String[] args) {
String s = "(W)|(U|V)";
ColumnVisibility v = new ColumnVisibility(s);
System.out.println(s);
printTree(0, s, v.getParseTree());
}
}
{noformat}
prints this:
{noformat}
(W)|(U|V)
OR 0 0
TERM W 1 2
OR (W)|(U|V 0 8
TERM U 5 6
TERM V 7 8
{noformat}
> ColumnVisibility parse tree nodes do not have correct location offsets for
> AND and OR nodes

> Project: Accumulo
> Issue Type: Bug
> Components: client
> Affects Versions: 1.4.0, 1.4.1, 1.4.2, 1.4.3, 1.4.4, 1.5.0
> Reporter: John Stoneham
> Assignee: Eric Newton
> Priority: Trivial
> Fix For: 1.4.5, 1.5.1, 1.6.0
>
>
> 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?
