Instance Method Details

#reset!(*names) ⇒ Object

Returns the named settings to their declared defaults (all of them with no arguments). reset_config! on the owning module discards the whole bag; this is the per-setting form, and the supported alternative to assigning nil, which is a VALUE rather than a reset.
