Debugging a Class Loader

.. versionadded:: 2.1
    The ``DebugClassLoader`` class was introduced in Symfony 2.1.

The :class:`Symfony\\Component\\ClassLoader\\DebugClassLoader` attempts to throw more helpful exceptions when a class isn't found by the registered autoloaders. All autoloaders that implement a findFile() method are replaced with a DebugClassLoader wrapper.

Using the DebugClassLoader is as easy as calling its static :method:`Symfony\\Component\\ClassLoader\\DebugClassLoader::enable` method:

use Symfony\Component\ClassLoader\DebugClassLoader;

DebugClassLoader::enable();
