Parameters

node

Expression

The expression to visit.

Returns

Expression

The modified expression, if it or any subexpression was modified; otherwise, returns the original expression.

Remarks

This can be overridden to visit or rewrite specific extension nodes.

If it is not overridden, this method will call VisitChildren, which gives the node a chance to walk its children. By default, VisitChildren will try to reduce the node.
