|
* One of the two classes that make up a core of event system in Acedia. |
|
* |
|
* 'Listener' (or it's child) class shouldn't be instantiated. |
|
* Usually module would provide '...ListenerBase' class that defines |
|
* certain set of static functions, corresponding to events it can listen to. |
|
* In order to handle those events you must create it's child class and |
|
* override said functions. But they will only be called if |
|
* 'SetActive(true)' is called for that child class. |
|
* To create you own '...ListenerBase' class you need to define |
|
* a static function for each event you wish it to catch and |
|
* set 'relatedEvents' variable to point at the 'Events' class |
|
* that will generate your events. |
|
* For concrete example look at |
|
* 'ConnectionEvents' and 'ConnectionListenerBase'. |
