Instance Method Details

#treeify(nodes, skipped: [], unlinked_trees: []) {|NodeBase| ... } ⇒ Array<Hash>

Note:

if block is no given, it auto-detects the serializer block.

Returns a hierarchical tree of nested Hashes via nodes key.

Yields:

Yield Returns:

  • (Hash) —

    custom hash model when treeifying (allows to set more keys/properties).

Returns:

  • (Array<Hash>) —

    a hierarchical tree of nested Hashes via nodes key.
