* Used by models to apply data processing.
* This allows for flexibility of integrators.
*
* E.g. pages are saved for each event.
* An integrator now can resolve them via data processing to arrays or menus.
*
* dataProcessing is configured via TypoScript for each plugin or whole extension via
* settings.dataProcessing.fqcn, e.g.:
*
* plugin.tx_events {
* settings {
* dataProcessing {
* Wrm\Events\Domain\Model\Event {
* 10 = TYPO3\CMS\Frontend\DataProcessing\MenuProcessor
* 10 {
* special = list
* special.value.field = pages
* dataProcessing {
* 10 = TYPO3\CMS\Frontend\DataProcessing\FilesProcessor
* 10 {
* references.fieldName = media
* }
* }
* }
* }
* }
* }
* }
*
* Currently supported by:
*
* - Event->getPages()
