__PACKAGE__->add_action('MyApp::Action::UpdateFoo');

add_action CLASS [, OPTIONS]
Merges the given action class into this one. Will "die" if the "action_class" in Jifty::Action::Record of the given "CLASS" doesn't match

trigger
Only run if this argument is provided
final
If this action runs, run only this action.
arguments
Merges together arguments from all of the actions added with "add_action". The record IDs to act on are stored (comma-separated) in an
argument named "ids", by default.
perform_action CLASS, IDS
Performs the given action "CLASS" on the given record "ID"s, which should be an array reference.
take_action
Completes the actions on all of the IDs given.
