Detailed Description

Reflection-based factory for controllers.

To ease development, this factory may be used for controllers with type-hinted arguments that resolve to services in the application container; this allows omitting the step of writing a factory for each controller.

You may use it as either an abstract factory:

'controllers' => [ 'abstract_factories' => [ LazyControllerAbstractFactory::class, ], ],

Or as a factory, mapping a controller class name to it:

'controllers' => [ 'factories' => [ MyControllerWithDependencies::class => LazyControllerAbstractFactory::class, ], ],

The latter approach is more explicit, and also more performant.

The factory has the following constraints/features:

• A parameter named `$config` typehinted as an array will receive the application "config" service (i.e., the merged configuration).
• Parameters type-hinted against array, but not named `$config` will be injected with an empty array.
• Scalar parameters will be resolved as null values.
• If a service cannot be found for a given typehint, the factory will raise an exception detailing this.
• Some services provided by Zend Framework components do not have entries based on their class name (for historical reasons); the factory contains a map of these class/interface names to the corresponding service name to allow them to resolve.

`$options` passed to the factory are ignored in all cases, as we cannot make assumptions about which argument(s) they might replace.
