vembedr S3 Classes

Description

Knowledge of these classes is not needed for day-to-day use. Rather, it is a bookkeeping device used to make it clearer to a developer how to add a new service.

Details

We use S3 classes to distinguish an embed object, and to denote which service it uses. Objects of these classes are created by embed_url() and each service's embed function.

vembedr_embed

• base class for all services

• HTML ⁠<div>⁠

• contains the embed code

There is an additional class attached according to the service:

• vembedr_embed_youtube

• vembedr_embed_youtube_short

• vembedr_embed_vimeo

• vembedr_embed_channel9

• vembedr_embed_box

• vembedr_embed_msstream

To support parsing, there is an internal S3 class attached to the URL being processed. It is named according to the service:

• vembedr_url_youtube

• vembedr_url_youtube_short

• vembedr_url_vimeo

• vembedr_url_channel9

• vembedr_url_box

• vembedr_url_msstream
