Prism::BasicVisitor

Class

A class that knows how to walk down the tree. None of the individual visit methods are implemented on this visitor, so it forces the consumer to implement each one that they need. For a default implementation that continues walking the tree, see the Visitor class.

Instance Methods

visit(node)

            # File tmp/rubies/ruby-3.3.0/lib/prism/visitor.rb, line 16
def visit(node)
  node&.accept(self)
end

Calls ‘accept` on the given node if it is not `nil`, which in turn should call back into this visitor by calling the appropriate `visit_*` method.

def visit_all(nodes)
  nodes.each { |node| node&.accept(self) }
end

Visits each node in ‘nodes` by calling `accept` on each one.

def visit_child_nodes(node)
  node.compact_child_nodes.each { |node| node.accept(self) }
end

Visits the child nodes of ‘node` by calling `accept` on each one.
