Feature: #94741 - Register SoftReference parsers via DI

See forge#94741


Parsers for soft references can now be registered via dependency injection in the corresponding Configuration/Services.(yaml|php) file of your extension. This is done by tagging your class with the new tag name softreference.parser and providing the parser key for the attribute parserKey.


    - name: softreference.parser
      parserKey: your_key

In addition, parsers now have to implement TYPO3\CMS\Core\DataHandling\SoftReference\SoftReferenceParserInterface. This interface describes the parse() method, which is very similar to the old method findRef(). The difference is that $parserKey (former known as $spKey) and $parameters (former known as $spParams) can now be optionally set with the setParserKey() method. The key can be retrieved with the getParserKey() method.

The return type has also been changed to TYPO3\CMS\Core\DataHandling\SoftReference\SoftReferenceParserResult. This model holds the former result array key entries content and elements as properties and has appropriate getter methods for them. It should be created by its own factory method SoftReferenceParserResult::create(), which expects both above-mentioned arguments to be provided. If the result is empty, SoftReferenceParserResult::createWithoutMatches() should be used instead.


Developers can register their user-defined soft reference parsers in their Configuration/Services.(yaml|php) file. In addition, parser have to implement the new interface TYPO3\CMS\Core\DataHandling\SoftReference\SoftReferenceParserInterface.
