Instance Method Details

#default_inversion_options(node, resource) ⇒ Object

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Set some default inversion provider options. Package name can’t get a default value here because that would complicate the handling of system_package_candidates.
