Instance Method Details

#destroy_item(klass, name, type_name) ⇒ Object

Extracted from Chef::Knife.delete_object, because it has a confirmation step built in… By specifying the ‘–purge’ flag (and also explicitly confirming the server destruction!) the user is already making their intent known. It is not necessary to make them confirm two more times.
