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

["Joe Ferner (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/ACCUMULO-2439?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Joe Ferner updated ACCUMULO-2439:
---------------------------------

    Description: 
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.
