    • Method Detail

      • innerEnd

        protected void innerEnd​(E category,
                        long duration)
        Description copied from class: AbstractActionStatsCollector
        The specific implementation of the "end" operation
        Specified by:
        innerEnd in class AbstractActionStatsCollector<E extends Enum<E>>
        Parameters:
        category - The action category
        duration - The measured action duration, in micros

      • startAndEnd

        public void startAndEnd​(E category)
        Description copied from interface: ActionStatsCollector
        Indicates the starting and termination of an "instant" action (duration = 0)
        Parameters:
        category - The category to place the action stats into

      • getRunning

        public int getRunning()
        Returns:
        The number of actions currently in execution

      • getCompletedCount

        public long getCompletedCount​(E category)
        Parameters:
        category - A stats category
        Returns:
        The number of actions of the given category that has been completed so far

      • getAll

        public ActionStatsMap<E> getAll()
        Returns:
