Interface ITaskPlanner

All Known Implementing Classes:
FIFOTaskPlanner
public interface ITaskPlanner

ITaskPlanner provides an interface to program your own task planning. It gives you operations for pick a task from the queue according on the criteria that you designed.

The simplest implementation of ITaskPlanner would be a FIFO task planner (see FIFOTaskPlanner.java) which takes jobs from a task queue in the same order they were put. But any kind of planner is possible (SJF, LIFO, RoundRobin, etc.).

  • Method Details

    • nextTask

      IRunnableTask nextTask()
      Takes the next task to be executed.
      Returns:
      IRunnableTask representing the next task to be executed

    • previousTask

      IRunnableTask previousTask()
      Takes the previous executed task. Notice that it may or may not have sense for specific implementations. For example, in a FIFO-like planner, the task is taken from the queue, executed until it is finished and removed from the queue. So, there is no previous task.
      Returns:
      IRunnableTask representing the previous executed task, or null if none.
