Yoast\WP\SEO\Generators

Open_Graph_Image_Generator::generate() public Yoast 1.0

Retrieves the images for an indexable.

For legacy reasons some plugins might expect we filter a WPSEO_Opengraph_Image object. That might cause type errors. This is why we try/catch our filters.

{} Это метод класса: Open_Graph_Image_Generator{}

Возвращает
