- visitor
- ExpressionVisitor
An instance of ExpressionVisitor.
Returns
The expression being visited, or an expression which should replace it in the tree.
Remarks
Override this method to provide logic to walk the node's children. A typical implementation will call visitor.Visit on each of its children, and if any of them change, should return a new copy of itself with the modified children.
