Class: ReorderNodeCommand\<TRow\>

Defined in: src/tree-editor/commands/reorder-node.ts:16

Swaps a node with its previous (up) or next (down) sibling within the same parent. A no-op when the node is already at the edge of its sibling list — execute() returns the same state reference and undo() does nothing.
