Class: RBS::AST::Visitor

Relationships & Source Files
Inherits: Object
Defined in: lib/rbs/ast/visitor.rb

Overview

The Visitor class implements the Visitor pattern for traversing the ::RBS Abstract Syntax Tree (AST).

It provides methods to visit each type of node in the ::RBS::AST, allowing for custom processing of each node type.

This class is designed to be subclassed, with specific visit methods overridden to implement custom behavior for different node types.

Example usage:

~~~rb class MyVisitor < Visitor

def visit_declaration_class(node)
  puts "Visiting class: #{node.name}"

  super # call {super} to run the default visiting behavior
end

end

visitor = MyVisitor.new visitor.visit(ast_node) ~~~
