Built-in Objects and Variables
------------------------------

When using this component inside a Symfony application, certain objects and
variables are automatically injected by Symfony so you can use them in your
expressions (e.g. the request, the current user, etc.):

* :doc:`Variables available in security expressions </security/expressions>`;
* :doc:`Variables available in service container expressions </service_container/expression_language>`;
* :doc:`Variables available in routing expressions </routing/conditions>`.
