public function EmptyParagraphKiller::prepare in Empty paragraph killer 8

Prepares the text for processing.

Filters should not use the prepare method for anything other than escaping, because that would short-circuit the control the user has over the order in which filters are applied.

Parameters

string $text: The text string to be filtered.

string $langcode: The language code of the text to be filtered.

Return value

string The prepared, escaped text.

Overrides FilterBase::prepare
