class StringLoader

Loads string templates, also known as inline templates.

This loader is intended to be used in a Twig loader chain and only loads string templates that begin with the following comment:

{# inline_template_start #}

This class override ensures that the string loader behaves as expected in the loader chain. If Twig's string loader is used as is, any string (even a reference to a file-based Twig template) is treated as a valid template and is rendered instead of a \Twig\Error\LoaderError exception being thrown.
