AstVisitor2<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

• SimpleAstVisitor2 which implements every visit method by doing nothing,
• RecursiveAstVisitor2 which causes every node in a structure to be visited, and
• ThrowingAstVisitor2 which implements every visit method by throwing an exception.

Implementers

• RecursiveAstVisitor2
• SimpleAstVisitor2
• ThrowingAstVisitor2
• TimedAstVisitor2
• UnifyingAstVisitor2

Annotations

• @experimental
• @AnalyzerPublicApi.new(message: 'exported by lib/dart/ast/ast.dart')
