That depends. In many cases you could use the $TSFE->cObj but in many
others you'll have to create your own.

So in the latter case I'd use the singleton design pattern. Here you go:

In your main class you create a function like this:

class mybaseclass {
   function &getCObjInstance()  {
      static $instance;
      if (!isset ($instance)) {
         $instance = t3lib_div::makeInstance('tslib_cObj');
      }
      return $instance;
}

Then, in all your other classes, it goes like this:

class myclassname {
   var $cObj;

   function myclassname () {
      $this->cObj =& mybaseclass::getCObjInstance;
   }
}

This advice was for free ;-)
