20 This module provides a "mock" counterpart to the
21 Net::DBus::Binding::Message class. It is basically a pure Perl fake
22 message object providing the same contract as the real message object.
23 It is intended for use internally by the testing APIs.
24
26 my $call = Net::DBus::Test::MockMessage->new_method_call( service_name
27 => $service, object_path => $object, interface => $interface,
28 method_name => $name);
29 Create a message representing a call on the object located at the
30 path "object_path" within the client owning the well-known name
31 given by "service_name". The method to be invoked has the name
32 "method_name" within the interface specified by the "interface"
33 parameter.
34 my $msg = Net::DBus::Test::MockMessage->new_method_return( replyto =>
36 $method_call);
37 Create a message representing a reply to the method call passed in
38 the "replyto" parameter.
39 my $signal = Net::DBus::Test::MockMessage->new_signal( object_path =>
41 $path, interface => $interface, signal_name => $name);
42 Creates a new message, representing a signal [to be] emitted by the
43 object located under the path given by the "object_path" parameter.
44 The name of the signal is given by the "signal_name" parameter, and
45 is scoped to the interface given by the "interface" parameter.
46 my $msg = Net::DBus::Test::MockMessage->new_error( replyto =>
48 $method_call, name => $name, description => $description);
49 Creates a new message, representing an error which occurred during
50 the handling of the method call object passed in as the "replyto"
51 parameter. The "name" parameter is the formal name of the error
52 condition, while the "description" is a short piece of text giving
53 more specific information on the error.
54 my $type = $msg->get_type
56 Retrieves the type code for this message. The returned value
57 corresponds to one of the four
58 "Net::DBus::Test::MockMessage::MESSAGE_TYPE_*" constants.
59 my $name = $msg->get_error_name
61 Returns the formal name of the error, as previously passed in via
62 the "name" parameter in the constructor.
63 my $interface = $msg->get_interface
65 Retrieves the name of the interface targetted by this message,
66 possibly an empty string if there is no applicable interface for
67 this message.
68 my $path = $msg->get_path
70 Retrieves the object path associated with the message, possibly an
71 empty string if there is no applicable object for this message.
72 my $name = $msg->get_destination
74 Retrieves the uniqe or well-known bus name for client intended to
75 be the recipient of the message. Possibly returns an empty string
76 if the message is being broadcast to all clients.
77 my $name = $msg->get_sender
79 Retireves the unique name of the client sending the message
80 my $serial = $msg->get_serial
82 Retrieves the unique serial number of this message. The number is
83 guarenteed unique for as long as the connection over which the
84 message was sent remains open. May return zero, if the message is
85 yet to be sent.
86 my $name = $msg->get_member
88 For method calls, retrieves the name of the method to be invoked,
89 while for signals, retrieves the name of the signal.
90 $msg->set_sender($name)
92 Set the name of the client sending the message. The name must be
93 the unique name of the client.
94 $msg->set_destination($name)
96 Set the name of the intended recipient of the message. This is
97 typically used for signals to switch them from broadcast to
98 unicast.
99 my $iterator = $msg->iterator;
101 Retrieves an iterator which can be used for reading or writing
102 fields of the message. The returned object is an instance of the
103 "Net::DBus::Binding::Iterator" class.
104 $boolean = $msg->get_no_reply()
106 Gets the flag indicating whether the message is expecting a reply
107 to be sent.
108 $msg->set_no_reply($boolean)
110 Toggles the flag indicating whether the message is expecting a
111 reply to be sent. All method call messages expect a reply by
112 default. By toggling this flag the communication latency is reduced
113 by removing the need for the client to wait
114 my @values = $msg->get_args_list
116 De-marshall all the values in the body of the message, using the
117 message signature to identify data types. The values are returned
118 as a list.
119 $msg->append_args_list(@values)
121 Append a set of values to the body of the message. Values will be
122 encoded as either a string, list or dictionary as appropriate to
123 their Perl data type. For more specific data typing needs, the
124 Net::DBus::Binding::Iterator object should be used instead.
125 my $sig = $msg->get_signature
127 Retrieves a string representing the type signature of the values
128 packed into the body of the message.
