29 This module provides an abstraction of a message queue. It derives from
30 the Directory::Queue::Simple module that provides a generic directory
31 based queue.
32
33 It simply stores the serialized message (with optional compression) as
34 a Directory::Queue::Simple element.
35
37 In addition to the methods inherited from Directory::Queue::Simple, the
38 following methods are available:
39
40 new(OPTIONS)
41 return a new Messaging::Message::Queue::DQS object (class method),
42 the OPTIONS are the ones for Directory::Queue::Simple->new() with
43 the addition of "compression", like for
44 Messaging::Message->jsonify()
45
46 add_message(MESSAGE)
47 add the given message (a Messaging::Message object) to the queue
48 and return the corresponding element name
49
50 get_message(ELEMENT)
51 get the message from the given element (which must be locked) and
52 return a Messaging::Message object
53
55 Directory::Queue::Simple, Messaging::Message,
56 Messaging::Message::Queue.
