    • updateLevelPriority

      public boolean updateLevelPriority()
      Updates the (potentially stale) priority value cached in this object. This should be called when this object is outside the queue.
      Returns:
      true if the level changed.

    • resetLevelPriority

      public void resetLevelPriority()
      Updates the task level priority to be greater than or equal to the minimum priority within that level. This ensures that tasks that spend time blocked do not return and starve already-running tasks. Also updates the cached priority object.

    • compareTo

      public int compareTo(PrioritizedSplitRunner o)
      Specified by:
      compareTo in interface Comparable<PrioritizedSplitRunner>

    • getSplitId

      public int getSplitId()

    • getPriority

      public Priority getPriority()

    • getInfo

      public String getInfo()

    • toString

      public String toString()
      Overrides:
      toString in class Object
