Breaking: #101281 - Introduce type declarations in ResourceInterface

Description

The following methods of interface \TYPO3\CMS\Core\Resource\ResourceInterface have been given return type declarations:

public function getIdentifier(): string;
public function getName(): string;
public function getStorage(): ResourceStorage;
public function getHashedIdentifier(): string;
public function getParentFolder(): FolderInterface;

Impact

This affects many classes due to the following implementation rules:

• \TYPO3\CMS\Core\Resource\Folder , because it implements \TYPO3\CMS\Core\Resource\FolderInterface which extends \TYPO3\CMS\Core\Resource\ResourceInterface
• \TYPO3\CMS\Core\Resource\FileReference , and \TYPO3\CMS\Core\Resource\AbstractFile because both implement \TYPO3\CMS\Core\Resource\FileInterface which extends \TYPO3\CMS\Core\Resource\ResourceInterface
• \TYPO3\CMS\Core\Resource\File and \TYPO3\CMS\Core\Resource\ProcessedFile because both extend \TYPO3\CMS\Core\Resource\AbstractFile

In consequence, the following methods are affected:

• \TYPO3\CMS\Core\Resource\Folder::getIdentifier()
• \TYPO3\CMS\Core\Resource\Folder::getName()
• \TYPO3\CMS\Core\Resource\Folder::getStorage()
• \TYPO3\CMS\Core\Resource\Folder::getHashedIdentifier()
• \TYPO3\CMS\Core\Resource\Folder::getParentFolder()
• \TYPO3\CMS\Core\Resource\FileReference::getIdentifier()
• \TYPO3\CMS\Core\Resource\FileReference::getName()
• \TYPO3\CMS\Core\Resource\FileReference::getStorage()
• \TYPO3\CMS\Core\Resource\FileReference::getHashedIdentifier()
• \TYPO3\CMS\Core\Resource\FileReference::getParentFolder()
• \TYPO3\CMS\Core\Resource\AbstractFile::getIdentifier()
• \TYPO3\CMS\Core\Resource\AbstractFile::getName()
• \TYPO3\CMS\Core\Resource\AbstractFile::getStorage()
• \TYPO3\CMS\Core\Resource\AbstractFile::getHashedIdentifier()
• \TYPO3\CMS\Core\Resource\AbstractFile::getParentFolder()
• \TYPO3\CMS\Core\Resource\File::getIdentifier()
• \TYPO3\CMS\Core\Resource\File::getName()
• \TYPO3\CMS\Core\Resource\File::getStorage()
• \TYPO3\CMS\Core\Resource\File::getHashedIdentifier()
• \TYPO3\CMS\Core\Resource\File::getParentFolder()
• \TYPO3\CMS\Core\Resource\ProcessedFile::getIdentifier()
• \TYPO3\CMS\Core\Resource\ProcessedFile::getName()
• \TYPO3\CMS\Core\Resource\ProcessedFile::getStorage()
• \TYPO3\CMS\Core\Resource\ProcessedFile::getHashedIdentifier()
• \TYPO3\CMS\Core\Resource\ProcessedFile::getParentFolder()

Affected installations

Affected installations are those which either implement the ResourceInterface directly (very unlikely) or those that extend any of mentioned implementations (Core classes).

The usage (the API) of those implementation itself has not changed!

Migration

Use the same return type declarations as ResourceInterface does.
