public class DbParenthesis

extends DbExpr

This expression has the result of putting parenthesis around another expression. i.e. "expr" becomes "( expr )". It should be noted that you won't usually use this class in your application code. Normally the order of evaluation of the SQL is implied by the parethesis in your Java code. i.e.

 DbExpr x = a.and((b.or(c)).and(d))
 

This will automatically retain the Java evaluation order...

 A AND ( (B OR C) AND D)
