Overview

The RubyProf::MethodInfo class stores profiling data for a method. One instance of the RubyProf::MethodInfo class is created per method called per thread. Thus, if a method is called in two different thread then there will be two RubyProf::MethodInfo objects created. RubyProf::MethodInfo objects can be accessed via the RubyProf::Profile object.
