/* A Task is some piece of code that must be executed regularly, no matter whether |
9 |
|
|
* the daemon has received any SMS. |
10 |

|

* Tasks exist in two flavours: persistant and temporary. |
12 |
torben |

* |
13 |
torben |
129 |
* A persistant task is one which lives throughout the execution of the smsdaemon instance. |
14 |
|
|
* A pointer to a persistant task can be retrieved via TaskManager::GetTask(std::string name), |
15 |
torben |
96 |
* and thus it must have a unique name. |
16 |
|
|
* |
17 |
|
|
* A temporary tasks is of a more short-lived nature. It behaves like a fire-and-forget piece of code. |
18 |
|
|
* A temporary task can be created at any time by any piece of code. This creation must be dynamicaly |
19 |
|
|
* through the new() operator. When created it registers itself with the task manager, and here after any |
20 |
|
|
* references to the task must be nulled. |
21 |
|
|
* When the temporary task has done its work it must set the protected variale to true, and the |
22 |
|
|
* task instance will here after be deleted by the task-manager. |
23 |
|
|
* Temporary tasks does not need a unique name, and once created you cannot get a pointer to it again. |
