Expression.VisitChildren(ExpressionVisitor) Expression.VisitChildren(ExpressionVisitor) Expression.VisitChildren(ExpressionVisitor) Expression.VisitChildren(ExpressionVisitor) Method

Definition

Reduces the node and then calls the visitor delegate on the reduced expression. The method throws an exception if the node is not reducible.

protected public:
 virtual System::Linq::Expressions::Expression ^ VisitChildren(System::Linq::Expressions::ExpressionVisitor ^ visitor);
protected internal virtual System.Linq.Expressions.Expression VisitChildren (System.Linq.Expressions.ExpressionVisitor visitor);
abstract member VisitChildren : System.Linq.Expressions.ExpressionVisitor -> System.Linq.Expressions.Expression
override this.VisitChildren : System.Linq.Expressions.ExpressionVisitor -> System.Linq.Expressions.Expression
Protected Friend Overridable Function VisitChildren (visitor As ExpressionVisitor) As Expression

Parameters

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.
