ExtendableTrait
This extension trait is used when access to the underlying base class is not available, such as classes that belong to the foundation framework (Laravel). It is currently used by the Controller and Model classes.

Properties
$extendableCallbacks
protected
static array<string|int, mixed>
$extendableCallbacks
= []
Used to extend the constructor of an extendable class. Eg:
Class::extend(function($obj) { })
$extendableGuardProperties
protected
static bool
$extendableGuardProperties
= true
Indicates if dynamic properties can be created.
$extendableStaticMethods
protected
static array<string|int, mixed>
$extendableStaticMethods
= []
Collection of static methods used by behaviors.
$extensionData
protected
array<string|int, mixed>
$extensionData
= ['extensions' => [], 'methods' => [], 'dynamicMethods' => [], 'dynamicProperties' => []]
Class reflection information, including behaviors.
