removeUnusedImageVariant() public method

This is triggered via the nodePropertyChanged event. Note: This method it triggered by the "nodePropertyChanged" signal, @see \Neos\ContentRepository\Domain\Model\Node::emitNodePropertyChanged()

public removeUnusedImageVariant ( Neos\ContentRepository\Domain\Model\NodeInterface $node, string $propertyName, mixed $oldValue, mixed $value ) : void
$node	Neos\ContentRepository\Domain\Model\NodeInterface	the affected node
$propertyName	string	name of the property that has been changed/added
$oldValue	mixed	the property value before it was changed or NULL if the property is new
$value	mixed	the new property value
return	void

    public function removeUnusedImageVariant(NodeInterface $node, $propertyName, $oldValue, $value)
    {
        if ($oldValue === $value || !$oldValue instanceof ImageVariant) {
            return;
        }

        $results = $this->nodeDataRepository->findNodesByRelatedEntities(array(ImageVariant::class => [$identifier]));
        // This case shouldn't happen as the query will usually find at least the node that triggered this call, still if there is no relation we can remove the ImageVariant.

            return;
