23 Catalyst::ActionChain - Chain of Catalyst Actions
31 This class represents a chain of Catalyst Actions. It behaves exactly like
32 the action at the *end* of the chain except on dispatch it will execute all
33 the actions in the chain in order.
39 Accessor for the action chain; will be an arrayref of the Catalyst::Action
40 objects encapsulated by this chain.
44 Dispatch this action chain against a context; will dispatch the encapsulated

52 my @chain = @{ $self->chain };
53 my $last = pop(@chain);

57 @args = splice(@captures, 0, $cap->[0]);
59 local $c->request->{arguments} = \@args;
60 $action->dispatch( $c );
62 $last->dispatch( $c );

67 Takes a list of Catalyst::Action objects and constructs and returns a
68 Catalyst::ActionChain object representing a chain of these actions
