org.apache.accumulo.core.security.ColumnVisibility
Validate the column visibility is a valid expression and set the visibility for a Mutation. See {@link ColumnVisibility#ColumnVisibility(byte[])} for thedefinition of an expression.
The expression is a sequence of characters from the set [A-Za-z0-9_-.] along with the binary operators "&" and "|" indicating that both operands are necessary, or the either is necessary. The following are valid expressions for visibility:
```
 A A|B (A|B)&(C|D) orange|(red&yellow) 
```
The following are not valid expressions for visibility:
```
 A|B&C A=B A|B| A&|B () ) dog|!cat 
```
In addition to the base set of visibilities, any character can be used in the expression if it is quoted. If the quoted term contains '"' or '\', then escape the character with '\'. The {@link #quote(String)} method can be used to properly quote and escape terms automatically. The following is an example of a quoted term:
```
 "A#C"&B 
```
