[jira] [Created] (ACCUMULO-2439) Add a NOT (!) operator to ColumnVisibility

------------------------------------

             Summary: Add a NOT (!) operator to ColumnVisibility
                 Key: ACCUMULO-2439
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-2439
             Project: Accumulo
          Issue Type: New Feature
          Components: master
    Affects Versions: 1.5.1
            Reporter: Joe Ferner
            Priority: Minor
         Attachments: ACCUMULO_2439.patch

This patch adds a NOT (!) operator to ColumnVisibility.

The syntax is as follows:
!a
(!a)&(!b)
a&(!b)
a&(!(b|c))

Because of the nature of the current visibility parsing algorithm the additional parentheses are required.

In the shell, the "!" requires escaping. This is due to how JLine parses the command and attempts to substitute "!" with history.
