class RubyProf::CallTreeVisitor

The call info visitor class does a depth-first traversal across a list of call infos. At each call_tree node, the visitor executes the block provided in the visit method. The block is passed two parameters, the event and the call_tree instance. Event will be either :enter or :exit.

visitor = RubyProf::CallTreeVisitor.new(result.threads.first.call_tree)

method_names = Array.new

visitor.visit do |call_tree, event|
  method_names << call_tree.target.full_name if event == :enter
end

puts method_names
