- visitor
- ExpressionVisitor
An instance of Func<T,TResult>.
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.
