공개 메소드들

메소드	설명
Flip ( ) : IJoinExpression	For some implementations, it's simpler to only implement one-sided joins. So to handle right (or left) joins, you want to flip the criteria so the right and left daos are swapped and you can do a left (or right) join instead.
Invert ( ) : IExpression	Produces an expression that is the exact opposite of this expression. The new expression should exclude everything this one includes, and include everything this one excludes.
ToString ( ) : string
TrueOrNot ( ) : bool	This tells you whether you want things that match, or things that don't match, this expression.
