/* Macro that registers the ITrigger subclass named in the trigger table.
|
| 7 |
*
|
| 8 |
* This macro works by creating a new class called <triggername>Factory that calls TriggerTable::registerTrigger()
|
| 9 |
* in its constructor. It also has a static method that creates an instance of the ITrigger subclass, this is the
|
| 10 |
* function pointer that is supplied to the TriggerTable.
|
| 11 |
*
|
| 12 |
* A single instance of the <triggername>Factory is instantiated at global scope (within whatever namespace the
|
| 13 |
* macro was called in) so that the trigger will be registered before control passes to main, or whatever the user
|
| 14 |
* entry point is.
