Node

Main read model of the {ContentSubgraphInterface}.

Immutable, Read Only. In case you want to modify it, you need to create Commands and send them to ContentRepository::handle.

Identity of a Node

The node's "Read Model" identity is summarized here {\Neos\ContentRepository\Core\SharedModel\Node\NodeAddress}, consisting of:

• {\Neos\ContentRepository\Core\SharedModel\ContentRepository\ContentRepositoryId}
• {\Neos\ContentRepository\Core\SharedModel\Workspace\WorkspaceName}
• {\Neos\ContentRepository\Core\DimensionSpace\DimensionSpacePoint}
• {\Neos\ContentRepository\Core\SharedModel\Node\NodeAggregateId}

The node address can be constructed via {\Neos\ContentRepository\Core\SharedModel\Node\NodeAddress::fromNode()} and serialized.

Traversing the graph

The node does not have structure information, i.e. no infos about its children. To f.e. fetch children, you need to fetch the subgraph and use findChildNodes on the subgraph:

$subgraph = $contentRepository->getContentGraph($node->workspaceName)->getSubgraph(
    $node->dimensionSpacePoint,
    $node->visibilityConstraints
);
$childNodes = $subgraph->findChildNodes($node->aggregateId, FindChildNodesFilter::create());

A note about the {\Neos\ContentRepository\Core\DimensionSpace\DimensionSpacePoint} and the {\Neos\ContentRepository\Core\DimensionSpace\OriginDimensionSpacePoint}

The {\Neos\ContentRepository\Core\Projection\ContentGraph\Node::dimensionSpacePoint} is the DimensionSpacePoint this node has been accessed in, and NOT the DimensionSpacePoint where the node is "at home". The DimensionSpacePoint where the node is (at home) is called the ORIGIN DimensionSpacePoint, and this can be accessed using {\Neos\ContentRepository\Core\Projection\ContentGraph\Node::originDimensionSpacePoint}. If in doubt, you'll usually need the DimensionSpacePoint instead of the OriginDimensionSpacePoint; you'll only need the OriginDimensionSpacePoint when constructing commands on the write side.
