module RubyProf

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

visitor = RubyProf::CallInfoVisitor.new(result.threads.first)

method_names = Array.new

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

puts method_names

These methods are here for backwards compatability with previous RubyProf releases

Returns what ruby-prof is measuring. Valid values include:

*RubyProf::PROCESS_TIME - Measure process time. This is default. It is implemented using the clock functions in the C Runtime library. *RubyProf::WALL_TIME - Measure wall time using gettimeofday on Linx and GetLocalTime on Windows *RubyProf::CPU_TIME - Measure time using the CPU clock counter. This mode is only supported on Pentium or PowerPC platforms. *RubyProf::ALLOCATIONS - Measure object allocations. This requires a patched Ruby interpreter. *RubyProf::MEMORY - Measure memory size. This requires a patched Ruby interpreter. *RubyProf::GC_RUNS - Measure number of garbage collections. This requires a patched Ruby interpreter. *RubyProf::GC_TIME - Measure time spent doing garbage collection. This requires a patched Ruby interpreter.*/
