Class ClassLoader

ClassLoader implements a PSR-0, PSR-4 and classmap class loader.

$loader = new \Composer\Autoload\ClassLoader(); // register classes with namespaces $loader->add('Symfony\Component', DIR.'/component'); $loader->add('Symfony', DIR.'/framework'); // activate the autoloader $loader->register(); // to enable searching the include path (eg. for PEAR packages) $loader->setUseIncludePath(true);

In this example, if you try to use a class in the Symfony\Component namespace or one of its children (Symfony\Component\Console for instance), the autoloader will first look for the class under the component/ directory, and it will then fallback to the framework/ directory if not found before giving up.

This class is loosely based on the Symfony UniversalClassLoader.

`public boolean`	# `getUseIncludePath( )` Can be used to check if the autoloader uses the include path to check for classes. Can be used to check if the autoloader uses the include path to check for classes. Returns boolean
`public`	# `setClassMapAuthoritative( boolean $classMapAuthoritative )` Turns off searching the prefix and fallback directories for classes that have not been registered with the class map. Turns off searching the prefix and fallback directories for classes that have not been registered with the class map. Parameters `$classMapAuthoritative`
`public boolean`	# `isClassMapAuthoritative( )` Should class lookup fail if not found in the current class map? Should class lookup fail if not found in the current class map? Returns boolean
`public`	# `setApcuPrefix( string\|null $apcuPrefix )` APCu prefix to use to cache found/not-found classes, if the extension is enabled. APCu prefix to use to cache found/not-found classes, if the extension is enabled. Parameters `$apcuPrefix`
`public string\|null`	# `getApcuPrefix( )` The APCu prefix in use, or null if APCu caching is not enabled. The APCu prefix in use, or null if APCu caching is not enabled. Returns string\|null

`public boolean\|null`	# `loadClass( string $class )` Loads the given class or interface. Loads the given class or interface. Parameters `$class` The name of the class Returns boolean\|null True if loaded, null otherwise
`public string\|false`	# `findFile( string $class )` Finds the path to the file where the class is defined. Finds the path to the file where the class is defined. Parameters `$class` The name of the class Returns string\|false The path if found, false otherwise
