NodeImpl class

The implementation of the node interface.

This Class denotes one node containing sub-nodes in a tree-like structure. Each node may have n children. Each node may be a skeleton-only node (contains only name and a reference to a mapper), or may be materialized (contains all data). Typically when fetching a node, the node is materialized but its sub-nodes are skeleton-only nodes. All skeleton nodes materialize automatically if their data is accessed.

Implemented types

Constructors

NodeImpl(String name, String nodeOwner, [String? parent, Visibility vis = Visibility.red, List<NodeValue> nodeValues = const <NodeValue>[]])

NodeImpl.createSkeleton(String path, String nodeOwner, StorageController? _controller)

Constructor creating a skeleton node.
