module RubyProf
# 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
