|
16 |
- * ClassLoader implements a PSR-0, PSR-4 and classmap class loader. |
|
17 |
- * |
|
18 |
- * $loader = new \Composer\Autoload\ClassLoader(); |
|
19 |
- * |
|
20 |
- * // register classes with namespaces |
|
21 |
- * $loader->add('Symfony\Component', __DIR__.'/component'); |
|
22 |
- * $loader->add('Symfony', __DIR__.'/framework'); |
|
23 |
- * |
|
24 |
- * // activate the autoloader |
|
25 |
- * $loader->register(); |
|
26 |
- * |
|
27 |
- * // to enable searching the include path (eg. for PEAR packages) |
|
28 |
- * $loader->setUseIncludePath(true); |
|
29 |
- * |
|
30 |
- * In this example, if you try to use a class in the Symfony\Component |
|
31 |
- * namespace or one of its children (Symfony\Component\Console for instance), |
|
32 |
- * the autoloader will first look for the class under the component/ |
|
33 |
- * directory, and it will then fallback to the framework/ directory if not |
|
34 |
- * found before giving up. |
|
35 |
- * |
|
36 |
- * This class is loosely based on the Symfony UniversalClassLoader. |
