Instance Method Summary

  • #child

    Previously, we had a child node on this class that contained either a constant read or a missing node.

  • #full_name

    Returns the full name of this constant path.

  • #full_name_parts

    Returns the list of parts for the full name of this constant path.

Node - Inherited

#deprecated, #newline_flag!

Instance Method Details

#child

Previously, we had a child node on this class that contained either a constant read or a missing node. To not cause a breaking change, we continue to supply that API.
