Public Methods

Method Description
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.
LeftPropertyValueEqualJoinExpression ( string property, object value ) : System

For joins that use one field from the Left DAO and compares on a value.
LeftPropertyValueEqualJoinExpression ( string property, object value, bool trueOrNot ) : System

For joins that use one field from the Left DAO and compares on a value.
