+# The AutoloaderFactory
+
+zend-loader provides multiple autoloader strategies.
+`Zend\Loader\AutoloaderFactory` allows you to define configuration for each
+strategy you wish to use and register them at once. As an example, you may have
+a class map for your most used classes, but want to use a PSR-0 style autoloader
+for 3rd party libraries. The factory uses configuration, allowing you to cache
+your autoloader definitions or define them centrally for your application.
+
+## Quick Start
+
+The `AutoloaderFactory` expects an array of configuration.
+
+```php
+$config = [
+    'Zend\Loader\ClassMapAutoloader' => [
+        'application' => APPLICATION_PATH . '/.classmap.php',
+        'zf'          => APPLICATION_PATH . '/../library/Zend/.classmap.php',
+    ],
+    'Zend\Loader\StandardAutoloader' => [
+        'namespaces' => [
+            'Phly\Mustache' => APPLICATION_PATH . '/../library/Phly/Mustache',
+            'Doctrine'      => APPLICATION_PATH . '/../library/Doctrine',
+        ],
+    ],
+];
+```
+
+Once you have your configuration in a PHP array, pass it to the
+`AutoloaderFactory`:
+
+```php
+// This example assumes that the AutoloaderFactory is itself autoloadable!
+use Zend\Loader\AutoloaderFactory;
+
+AutoloaderFactory::factory($config);
+```
+
+The `AutoloaderFactory` will instantiate each autoloader with the given options,
+and also call its `register()` method to register it with the SPL autoloader.
+
+## Configuration options
+
+The `AutoloaderFactory` expects an associative array or `Traversable` object.
+Keys should be valid autoloader class names, and the values should be the
+options that should be passed to the class constructor.
+
+Internally, the `AutoloaderFactory` checks to see if the autoloader class
+referenced exists. If not, it will use the [StandardAutoloader](standard-autoloader.md)
+to attempt to load the class via the [include_path](http://php.net/include_path).
+If the class is not found, or does not implement the
+[SplAutoloader](spl-autoloader.md) interface, an exception will be raised.
+
+## Available methods
+
+### factory  
+
+```php
+static factory(array|Traversable $options) : void
+```
+
+Instantiate and register autoloaders.
+
+This method is **static**, and is used to instantiate autoloaders and register them
+with the SPL autoloader. It expects either an array or `Traversable` object as denoted in the
+[options section](#configuration options).
+
+### getRegisteredAutoloaders  
+
+```php
+static getRegisteredAutoloaders() : SplAutoloader[]
+```
+
+Retrieve a list of all autoloaders registered using the factory.
+
+This method is **static**, and may be used to retrieve a list of all autoloaders
+registered via the `factory()` method. It returns an array of `SplAutoloader`
+instances.
+
+### getRegisteredAutoloader  
+
+```php
+static getRegisteredAutoloader($class) : SplAutoloader
+```
+
+Retrieve an autoloader by class name.
+
+This method is **static**, and is used to retrieve a specific autoloader by
+class name. If the autoloader is not registered, an exception will be thrown.
+
+### unregisterAutoloaders  
+
+```php
+static unregisterAutoloaders() : void
+```
+
+Unregister all autoloaders registered via the factory.
+
+This method is **static**, and can be used to unregister all autoloaders that
+were registered via the factory. Note that this will **not** unregister
+autoloaders that were registered outside of the factory.
+
+### unregisterAutoloader  
+
+```php
+static unregisterAutoloader($class) : bool
+```
+
+Unregister an autoloader registered via the factory.
+
+This method is **static**, and can be used to unregister an autoloader that was
+registered via the factory. Note that this will **not** unregister autoloaders
+that were registered outside of the factory. If the autoloader is registered via
+the factory, after unregistering it will return `TRUE`, otherwise `FALSE`.

+# The ClassMapAutoloader
+
+The `ClassMapAutoloader` is designed with performance in mind. Instead of doing
+a filesystem lookup, it checks the class against an in-memory classmap, loading
+the file associated with that class on a match.  This avoids unnecessary
+filesystem operations, and can also ensure the autoloader "plays nice" with
+opcode caches and PHP's realpath cache.
+
+The zend-loader component provides a tool for generating classmaps via
+`bin/classmap_generator.php`; read the [tool's documentation](classmap-generator.md) for more details.
+
+## Quick Start
+
+The first step is to generate a class map file. You may run this over any
+directory containing source code anywhere underneath it.
+
+```bash
+$ php classmap_generator.php Some/Directory/
+```
+
+This will create a file named `Some/Directory/autoload_classmap.php`, which is a
+PHP file returning an associative array that represents the class map.
+
+Within your code, you will now instantiate the `ClassMapAutoloader`, and provide
+it the location of the map.
+
+```php
+// This example assumes the ClassMapAutoloader is autoloadable.
+use Zend\Loader\ClassMapAutoloader;
+
+$loader = new ClassMapAutoloader();
+
+// Register the class map:
+$loader->registerAutoloadMap('Some/Directory/autoload_classmap.php');
+
+// Register with spl_autoload:
+$loader->register();
+```
+
+At this point, you may now use any classes referenced in your class map.
+
+## Configuration Options
+
+The `ClassMapAutoloader` expects an array of options, where each option is
+either a filename referencing a class map, or an associative array of class
+name/filename pairs.
+
+As an example:
+
+```php
+// Configuration defining both a file-based class map, and an array map
+$config = [
+    __DIR__ . '/library/autoloader_classmap.php', // file-based class map
+    [                                             // array class map
+        'Application\Bootstrap' => __DIR__ . '/application/Bootstrap.php',
+        'Test\Bootstrap'        => __DIR__ . '/tests/Bootstrap.php',
+    ],
+];
+```
+
+## Available Methods
+
+### \_\_construct  
+
+```php
+__construct(array|Traversable $options = null) : void
+```
+
+Initialize and configure the object `__construct($options = null)`; `$options`
+will be passed to [setOptions()](#setoptions).
+
+### setOptions  
+
+```php
+setOptions(array|Traversable $options) : void
+```
+
+Configures the state of the autoloader, including registering class maps.
+`$options` will be passed to [registerAutoloadMaps()](#registerautoloadmaps).
+
+### registerAutoloadMap  
+
+```php
+registerAutoloadMap(string|array $map) : void
+```
+
+Registers a class map with the autoloader. `$map` may be either a string
+referencing a PHP script that returns a class map, or an array defining a class
+map.
+
+More than one class map may be registered; each will be merged with the
+previous, meaning it's possible for a later class map to overwrite entries from
+a previously registered map.
+
+### registerAutoloadMaps  
+
+```php
+registerAutoloadMaps(array|Traversable $maps) : void
+```
+
+Register multiple class maps with the autoloader, iterating over `$maps` and
+passing each value to [registerAutoloadMap()](#registerautoloadmap).
+
+### getAutoloadMap  
+
+```php
+getAutoloadMap() : array
+```
+
+Retrieves the current class map as an associative array.
+
+### autoload  
+
+```php
+autoload(string $class) : false|string
+```
+
+Attempts to load the class specified. Returns a boolean `false` on failure, or a
+string indicating the class loaded on success.
+
+### register  
+
+```php
+register() : void
+```
+
+Registers the `autoload()` method of the current instance with
+`spl_autoload_register()`.
+
+## Examples
+
+### Using configuration to seed ClassMapAutoloader
+
+You can use configuration to seed a `ClassMapAutoloader`; values might come from
+a configuration file, a cache, or even a PHP array.  The following is an example
+of a PHP array that could be used to configure the autoloader:
+
+```php
+// Configuration defining both a file-based class map, and an array map
+$config = [
+    APPLICATION_PATH . '/../library/autoloader_classmap.php', // file-based class map
+    [                                                         // array class map
+        'Application\Bootstrap' => APPLICATION_PATH . '/Bootstrap.php',
+        'Test\Bootstrap'        => APPLICATION_PATH . '/../tests/Bootstrap.php',
+    ],
+];
+```
+
+Once you have your configuration, you can pass it either to the constructor of
+the `ClassMapAutoloader`, to its `setOptions()` method, or to
+`registerAutoloadMaps()`.
+
+```php
+use Zend\Loader\ClassMapAutoloader;
+
+/* The following are all equivalent */
+
+// To the constructor:
+$loader = new ClassMapAutoloader($config);
+
+// To setOptions():
+$loader = new ClassMapAutoloader();
+$loader->setOptions($config);
+
+// To registerAutoloadMaps():
+$loader = new ClassMapAutoloader();
+$loader->registerAutoloadMaps($config);
+```
