------------------------------------
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.
