Is possibile to hide $article object

Question

I'm developing a content plugin to filter articles according to a field in CB profile.

Something like:

public function onContentPrepare ($context, &$article, &$params, $limitstart)
    {
    ...code for CB setup...

Global $_CB_framework;
$CB=$_CB_framework;
$cbUser =& CBuser::getInstance( $myId );

if ( ! $cbUser ) {
     $cbUser =& CBuser::getInstance( null );
}

//Select the value choosen by the user in a specific field
    $category = $cbUser->getField( 'cb_category' );
//Catch the category title
    $cat=&$article->category_title;
//Put the user value in $esc
    $esc= array ($category); 
//If the value of the user choice correspond to the name of the category
    if(in_array($cat, $esc) ) {

// Hide the entire article.
// Now what i do is hide title, text, hits and other properties of $article
    unset($article->title);
    unset($article->introtext);
    unset($article->text);
    unset($article->hits);

}

 else
    echo (' </br>Nothing to do</br>'); 
    }

To hide all content I've tried to unset $article property like $article->text and it's work.

But...I need more...
I need to unset the entire $article object.

Unset or hide.
I've tried to change $article state property to state->0 (unpublished) but works like a simple label and the article was still displayed. Any idea about it?

Thanks in advance!

No you cannot unset the whole $article object, you can only unset its properties.
