Feature: #81330 - Trait to migrate public access to protected by deprecation¶
See Issue #81330 See Important-81330-DealingWithPropertiesThatAreMigratedToProtected.rst
A new PHP trait (
PublicPropertyDeprecationTrait) is added to support the smooth migration of public properties to
a protected or private state of a property. By using this trait, deprecation warnings are thrown until the next
major TYPO3 version.
Instead of creating a breaking change by setting a public property to protected, the migration can now by done by the softer path of deprecation. This will encourage the encapsulation of core classes that still have public properties. By reaching encapsulation, refactoring becomes a lot more easy. The core can be modernized more quickly with less issues for developers.
