class Chef::Mixin::WhyRun::ConvergeActions
ConvergeActions
implements the logic for why run. A ConvergeActions
object wraps a collection of actions, which consist of a descriptive string and a block/Proc. Actions are executed by calling converge! When why_run mode is enabled, each action’s description will be printed, but the block will not be called. Conversely, in normal mode, the block is called, but the message is not printed.
In general, this class should be accessed through the API provided by Chef::Provider
.
