published? api call?

Is there a api call or function to determine if a document page is published or not? I cant seem to find or seach for it anywhere.

something like:

$page = $modx->getDocument(2);
if ($page[ispublish]) {

....

}

or something like that

Use the published document object:

published - [0|1] Whether or not the document is published.

Also the getDocument function has a built in setting to filter published/unpublished files
