class TestProf::MemoryProf::Tracker

  • track - a method that fetches the amount of memory in use at a certain point.
    * groups – the top n groups, an instance of Utils::SizedOrderedSet.
    * examples – the top n examples, an instance of Utils::SizedOrderedSet.
    list is an instance of LinkedList (for more info see tracker/linked_list.rb)
    * list - a linked list that is being used to track memmory for individual groups/examples.
    A tracker consists of four main parts:
    AllocTracker and RssTracker.
    the top n examples and groups. There are two types of trackers:
    Tracker is responsible for tracking memory usage and determining
