* ITaskPlanner provides an interface to program your own task planning. It gives
|
| 44 |
* you operations for pick a task from the queue according on the criteria that

| 45 |
* you designed.<br>

|

|

* The simplest implementation of ITaskPlanner would be a FIFO task planner (see
|
| 49 |
* FIFOTaskPlanner.java) which takes jobs from a task queue in the same order
|
| 50 |
* they were put. But any kind of planner is possible (SJF, LIFO, RoundRobin, etc.).
