ElementVisitor2<R> class abstract

An object that can be used to visit an element structure.

Clients may not extend, implement or mix-in this class. There are classes that implement this interface that provide useful default behaviors in package:analyzer/dart/element/visitor.dart. A couple of the most useful include

• SimpleElementVisitor which implements every visit method by doing nothing,
• RecursiveElementVisitor which will cause every node in a structure to be visited, and
• ThrowingElementVisitor which implements every visit method by throwing an exception.

Implementers

• GeneralizingElementVisitor2
• RecursiveElementVisitor2
• SimpleElementVisitor2
• ThrowingElementVisitor2
