/**

|
* Loads a template from a string.
|
|
14
|
*
|
|
15
|
* This loader should only be used for unit testing as it has many limitations
|
|
16
|
* (for instance, the include or extends tag does not make any sense for a string
|
|
17
|
* loader).
|
|
18
|
*
|
|
19
|
* When using this loader with a cache mechanism, you should know that a new cache
|
|
20
|
* key is generated each time a template content "changes" (the cache key being the
|
|
21
|
* source code of the template). If you don't want to see your cache grows out of
|
|
22
|
* control, you need to take care of clearing the old cache file by yourself.
