Extendable
Extension class
class Winter\Storm\Extension\ExtendableIf a class extends this class, it will enable support for using "Private traits".
Usage:
public $implement = ['Path.To.Some.Namespace.Class'];
See the ExtensionBase class for creating extension classes.
Traits
| Trait | Description |
|---|---|
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
public
$implement
:
string
|
array
|
null
= null
Extensions implemented by this class.
protected
$extendableConstructed
:
bool
= false
Indicates if the extendable constructor has completed.
protected
$localCallbacks
:
array
= []
This stores any locally-scoped callbacks fired before the extendable constructor had completed.
inherited

extendableAddExtension (callable $callback, boolean $scoped = false, $outerScope = null)
: void
Extends the class using a closure.
The closure will be provided a single parameter which is the instance of the extended class, by default.
You may optionally specify the callback as a scoped callback, which inherits the scope of the extended class and
provides access to protected and private methods and properties. This makes any call using $this act on the
extended class, not the class providing the extension.
If you use a scoped callback, you can provide the "outer" scope - or the scope of the class providing the extension, with the third parameter. The outer scope object will then be passed as the single parameter to the closure.
| Property | Type | Description |
|---|---|---|
| $callback | callable |

| $scoped | boolean |

protected
extendableAddLocalExtension (Closure $callback, $outerScope = null)
Adds local extensibility to the current instance.
This rebinds a given closure to the current instance, making it able to access protected and private methods. This
makes any call using $this within the closure act on the extended class, not the class providing the extension.
An outer scope may be provided by providing a second parameter, which will then be passed through to the closure as its first parameter. If this is not given, the current instance will be provided as the first parameter.
