[TYPO3-english] extension codes

[tom]

Hi,

...
  $conf = $this->conf['list.'];
  $conf['edit.']['parse.']['stdWrap.']['typolink.']['parameter'] =
$this->pi_getFFvalue($this->cObj->data['pi_flexform'], 'EDIT', 'list');
  $this->fields = t3lib_div::trimExplode(',', $conf['fields'], TRUE);
...

what is the meaning of above codes? It is from one extension source code.

Thanks.

Tom
