Subject [jira] [Updated] (ACCUMULO-2439) Add a NOT (!) operator to ColumnVisibility
Date Mon, 10 Mar 2014 15:39:51 GMT

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

Mike Drob 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.
