AstVisitor<R> class abstract

An object that can be used to visit an AST 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/ast/visitor.dart. A couple of the most useful include

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

Implementers

• GeneralizingAstVisitor
• RecursiveAstVisitor
• SimpleAstVisitor
• ThrowingAstVisitor
• TimedAstVisitor
• UnifyingAstVisitor
