|
|
|
* Factory class registered in ServiceProvider to create a ViewHelperResolver. |
|
25
|
|
|
* |
|
26
|
|
|
* Note fluid is a failsafe mode aware extensions since its used in the install |
|
27
|
|
|
* tool. We thus need a ServiceProvider.php to correctly instantiate / inject |
|
28
|
|
|
* these class objects. This would be simple, but ViewHelperResolver has state, |
|
29
|
|
|
* and the failsafe mode expects injected services to not have state. |
|
30
|
|
|
* |
|
31
|
|
|
* So, to retrieve a ViewHelperResolver instance, an instance of this factory |
|
32
|
|
|
* is retrieved instead (which is a singleton), which then creates a 'fresh' |
|
33
|
|
|
* instance of the ViewHelperResolver each time create() is called. |
|
34
|
|
|
* |
|
35
|
|
|
* @internal May change / vanish any time |
