NAME

6       Net::CLI::Interact::ActionSet - Conversation of Send and Match Actions
7

DESCRIPTION

9       This class is used internally by Net::CLI::Interact and it's unlikely
10       that an end-user will need to make use of ActionSet objects directly.
11       The interface is documented here as a matter of record.
12
13       An ActionSet comprises a sequence (usefully, two or more) of Actions
14       which describe a conversation with a connected network device. Actions
15       will alternate between type "send" and "match", perhaps not in their
16       original Phrasebook definition, but certainly by the time they are
17       used.
18
19       If the first Action is of type "send" then the ActionSet is a normal
20       sequence of "send a command" then "match a response", perhaps repeated.
21       If the first Action is of type "match" then the ActionSet represents a
22       "continuation", which is the method of dealing with paged output.
23

INTERFACE

25   default_continuation
26       An ActionSet ("match" then "send") which will be available for use on
27       all commands sent from this ActionSet. An alternative to explicitly
28       describing the Continuation sequence within the Phrasebook.
29
30   current_match
31       A stash for the current Prompt (regular expression reference) which
32       Net::CLI::Interact expects to see after each command. This is passed
33       into the constructor and is used when padding Match Actions into the
34       ActionSet (see "execute", below).
35
36   clone
37       Returns a new ActionSet which is a shallow clone of the existing one.
38       All the reference based slots will share data, but you can add (for
39       example) a "current_match" without affecting the original ActionSet.
40       Used when preparing to execute an ActionSet which has been retrieved
41       from the Phrasebook.
42
43   apply_params
44       Accepts a list of parameters which will be used when "sprintf" is
45       called on each Send Action in the set. You must supply sufficient
46       parameters as a list for all Send Actions in the set, and they will be
47       popped off and stashed with the Action(s) according to how many are
48       required.
49
50   register_callback
51       Allows the Transport to be registered such that when the ActionSet is
52       executed, commands are sent to the registered callback subroutine. May
53       be called more than once, and on execution each of the callbacks will
54       be run, in turn and in order.
55
56   execute
57       The business end of this class, where the sequence of Actions is
58       prepared for execution and then control passed to the Transport. This
59       process is split into a number of phases:
60
61       Pad "send" with "match"
62           The Phrasebook allows missing out of the Match statements between
63           Send statements, when they are expected to be the same as the
64           "current_match".  This phase inserts Match statements to restore a
65           complete ActionSet definition.
66
67       Forward "continuation" to "match"
68           In the Phrasebook a user defines a Continuation ("match", then
69           "send") following a Send statement (because it deals with the
70           response to the sent command). However they are actually used by
71           the Match, as it's the Match which captures output.
72
73           This phase copies Continuation ActionSets from Send statements to
74           following Match statements in the ActionSet. It also performs a
75           similar action using the "default_continuation" if one is set and
76           there's no existing Continuation configured.
77
78       Callback(s)
79           Here the registered callbacks are executed (i.e. data is sent to
80           the Transport).
81
82       Marshall Responses
83           Finally, responses which are stashed in the Match Actions are
84           copied back to the Send actions, as more logically they are
85           responses to commands sent. The ActionSet is now ready for access
86           to retrieve the "last_response" from the device.
