Rudy::Routines

Every Rudy routine is associated to a handler. There are four standard handler types: Startup, Shutdown, Reboot, and Passthrough. The first three are associated to routines of the same same. All other routines are handled by Rudy::Routines::Passthrough.

An individual routine is made up of various actions. Each action is associated to one of the following handlers: depends, disk, script, user. See each handler for the list of actions it is responsible for.

Public class methods

add_handler (name, klass)

Add a routine handler to @@handler.

75:     end

add_routine (name, klass)

Add a routine handler to @@routine.

routine_name Literally the name of the routine that will have a special handler, like startup, shutdown, and reboot.
handler The class that will handle this routine. It must inherit Rudy::Routine::Base

Returns the value of handler.
