SYNOPSIS

16         my @frames = Net::AMQP->parse_raw_frames(\$input);
17
18         ...
19
20         foreach my $frame (@frames) {
21             if ($frame->can('method_frame') && $frame->method_frame->isa('Net::AMQP::Protocol::Connection::Start')) {
22                 my $output = Net::AMQP::Frame::Method->new(
23                     channel => 0,
24                     method_frame => Net::AMQP::Protocol::Connection::StartOk->new(
25                         client_properties => { ... },

31                         },
32                     ),

DESCRIPTION

39       This module implements the frame (de)serialization and representation
40       of the Advanced Message Queue Protocol (http://www.amqp.org/).  It is
41       to be used in conjunction with client or server software that does the
42       actual TCP/IP communication.
43

CLASS METHODS

45   parse_raw_frames
46         Net::AMQP->parse_raw_frames(\$binary_payload)
47
48       Given a scalar reference to a binary string, return a list of
49       Net::AMQP::Frame objects, consuming the data in the string.  Croaks on
50       invalid input.
51

SEE ALSO

54       POE::Component::Client::AMQP

AMQP VERSIONS

57       AMQP 0-8 is fully supported.
58
59       AMQP 0-9, 0-9-1, and 0-10 are usably supported.  There are
60       interoperability issues with table encodings because the standard
61       disagrees with the dialects of major implementations (RabbitMQ and
62       Qpid).  For now, Net::AMQP limits itself to universally agreed table
63       elements.  See <http://www.rabbitmq.com/amqp-0-9-1-errata.html> for
64       details.
65
66       AMQP 1.0 has not been tested.
67

TODO

69       Address the dialect problem, either via modified spec files that
70       completely control the wire protocol, or by programmatic request.  The
71       former has precedent (viz "qpid.amqp0-8.xml" in spec), but could cause
72       a combinatorial explosion as more brokers and versions are added.  The
73       latter adds interface complexity.

QUOTES

76       "All problems in computer science can be solved by another level of
77       indirection." -- David Wheeler's observation
78
79       "...except for the problem of too many layers of indirection." --
80       Kevlin Henney's corollary
