Function: buildTreeState()

buildTreeState<TRow>(data, config): TreeState<TRow>

Defined in: src/tree-editor/build-tree-state.ts:29

Converts the user’s data array plus a treeData config into a TreeState.

• When getChildren is provided, the data is treated as nested and walked recursively. Children order is preserved.
• When only getParentId is provided, the data is treated as flat, parent-pointer rows: root order and sibling order follow input order.
• When neither accessor is provided, every row becomes a root.

The result is a fresh TreeState with no shared structure with the input — commands can safely mutate clones without leaking back to user data.
