		$component = `null`
	)

protected

Mark a property as deprecated.

Only use this for properties that used to be public and only call it in the constructor.

Parameters

string	$property	The name of the property.
string	$version	MediaWiki version where the property became deprecated.
string \| null	$class	The class which has the deprecated property. This can usually be guessed, but PHP can get confused when both the parent class and the subclass use the trait, so it should be specified in classes meant for subclassing.
string \| null	$component

Parameters

string $property

Returns: string|bool Best guess for the class in which the property is defined. False if the object does not have such a property.

Variable Documentation

◆ DeprecationHelper

trait DeprecationHelper

Initial value:

{
 
    protected string[][] $deprecatedPublicProperties = []

Use this trait in classes which have properties for which public access is deprecated.

Set the list of properties in $deprecatedPublicProperties and make the properties non-public. The trait will preserve public access but issue deprecation warnings when it is needed.

Example usage: class Foo { use DeprecationHelper; protected $bar; public function construct() { $this->deprecatePublicProperty( 'bar', '1.21', __CLASS ); } }

$foo = new Foo; $foo->bar; // works but logs a warning

Cannot be used with classes that have their own __get/__set methods.

Since: 1.32
