func (*Renamer) Rename ¶

func (r *Renamer) Rename(nodes []domain.Node, oldID, newID string) ([]domain.Node, error)

Rename changes a node's ID and updates all references pointing to it. Returns a new slice with the renamed node and updated references. The original nodes slice is not modified.

Parameters:

• nodes: slice of all nodes in the graph
• oldID: the current ID of the node to rename
• newID: the new ID for the node

Returns:

• updated slice of nodes with the rename applied
• error if oldID doesn't exist, newID already exists, or IDs are invalid

func (*Renamer) UpdateReferences ¶

func (r *Renamer) UpdateReferences(nodes []domain.Node, oldID, newID string) ([]domain.Node, error)

UpdateReferences updates all references from oldID to newID across all nodes. Unlike Rename, this does not require oldID to exist as a node - useful for detecting manual renames where the old node file was already deleted/renamed. Returns a new slice with updated references. Nodes whose references were updated will have their version incremented.
