No subject

ext_typoscript_setup.txt, but some not.

So my question is:

what is inside $conf? or what files compose $conf?


2. class.tx_jcjob_pi1.php

...
$this->template = $this->cObj->fileResource($this->conf['templateFile']);
...

class.tslib_pibase.php

...
var $cObj;
...

class.tslib_content.php

...
function fileResource
...

Question: How does this line work:
$this->cObj->fileResource($this->conf['templateFile']);?

a. there is not such codes: such as $cObj = new tslib_cObj(), how did $cObj get
instantiated?
b. there is no such codes like require_once('class.tslib_content.php'); how
could $this->cObjuse the method in class.tslib_content.php?


Thanks.
