File

Class

MediaEmbed

Provides a filter to embed media items using a custom tag.

Namespace

Drupal\media\Plugin\Filter

Code

    // Due to render caching and delayed calls, filtering happens later
    // in the rendering process through a '#pre_render' callback, so we
    // need to generate a counter for the media entity that is being embedded.
