/**
* Builds a base validator conjunction for the given data type.
*
* The base validation rules are those which were declared directly in a class (typically
* a model) through some validate annotations on properties.
*
* If a property holds a class for which a base validator exists, that property will be
* checked as well, regardless of a validate annotation
*
* Additionally, if a custom validator was defined for the class in question, it will be added
* to the end of the conjunction. A custom validator is found if it follows the naming convention
* "Replace '\Model\' by '\Validator\' and append 'Validator'".
*
* Example: $targetClassName is TYPO3\Foo\Domain\Model\Quux, then the validator will be found if it has the
* name TYPO3\Foo\Domain\Validator\QuuxValidator
*
* @param string $indexKey The key to use as index in $this->baseValidatorConjunctions; calculated from target class name and validation groups
* @param string $targetClassName The data type to build the validation conjunction for. Needs to be the fully qualified class name.
* @param array $validationGroups The validation groups to build the validator for
* @return void
* @throws \TYPO3\CMS\Extbase\Validation\Exception\NoSuchValidatorException
* @throws \InvalidArgumentException
