Renders a row object.

This usually passes through to a theme template of some form, but not always.

Parameters

object $row: A single row of the query result, so an element of $view->result.

Return value

string The rendered output of a single row, used by the style plugin.

Overrides RowPluginBase::render

File

core/modules/node/src/Plugin/views/row/Rss.php, line 74

Class

Rss

Performs a node_view on the resulting object and formats it as an RSS item.

Namespace

Drupal\node\Plugin\views\row

Code

public function render($row) {
  global $base_url;
