NAME
Net::DBus::Test::MockMessage - Fake a message object when unit testing
SYNOPSIS
Sending a message
my $msg = new Net::DBus::Test::MockMessage;
my $iterator = $msg->iterator;
$iterator->append_byte(132);
$iterator->append_int32(14241);
$connection->send($msg);
DESCRIPTION
This module provides a "mock" counterpart to the
Net::DBus::Binding::Message class. It is basically a pure Perl fake
message object providing the same contract as the real message object.
It is intended for use internally by the testing APIs.
METHODS
my $call = Net::DBus::Test::MockMessage->new_method_call( service_name
=> $service, object_path => $object, interface => $interface,
method_name => $name);
Create a message representing a call on the object located at the
path "object_path" within the client owning the well-known name
given by "service_name". The method to be invoked has the name
"method_name" within the interface specified by the "interface"
parameter.
my $msg = Net::DBus::Test::MockMessage->new_method_return( replyto =>
$method_call);
Create a message representing a reply to the method call passed in
the "replyto" parameter.
my $signal = Net::DBus::Test::MockMessage->new_signal( object_path =>
$path, interface => $interface, signal_name => $name);
Creates a new message, representing a signal [to be] emitted by the
object located under the path given by the "object_path" parameter.
The name of the signal is given by the "signal_name" parameter, and
is scoped to the interface given by the "interface" parameter.
my $msg = Net::DBus::Test::MockMessage->new_error( replyto =>
$method_call, name => $name, description => $description);
Creates a new message, representing an error which occurred during
the handling of the method call object passed in as the "replyto"
parameter. The "name" parameter is the formal name of the error
condition, while the "description" is a short piece of text giving
more specific information on the error.
my $type = $msg->get_type
Retrieves the type code for this message. The returned value
corresponds to one of the four
"Net::DBus::Test::MockMessage::MESSAGE_TYPE_*" constants.
my $name = $msg->get_error_name
Returns the formal name of the error, as previously passed in via
the "name" parameter in the constructor.
my $interface = $msg->get_interface
Retrieves the name of the interface targeted by this message,
possibly an empty string if there is no applicable interface for
this message.
my $path = $msg->get_path
Retrieves the object path associated with the message, possibly an
empty string if there is no applicable object for this message.
my $name = $msg->get_destination
Retrieves the unique or well-known bus name for client intended to
be the recipient of the message. Possibly returns an empty string if
the message is being broadcast to all clients.
my $name = $msg->get_sender
Retireves the unique name of the client sending the message
my $serial = $msg->get_serial
Retrieves the unique serial number of this message. The number is
guaranteed unique for as long as the connection over which the
message was sent remains open. May return zero, if the message is
yet to be sent.
my $name = $msg->get_member
For method calls, retrieves the name of the method to be invoked,
while for signals, retrieves the name of the signal.
$msg->set_sender($name)
Set the name of the client sending the message. The name must be the
unique name of the client.
$msg->set_destination($name)
Set the name of the intended recipient of the message. This is
typically used for signals to switch them from broadcast to unicast.
my $iterator = $msg->iterator;
Retrieves an iterator which can be used for reading or writing
fields of the message. The returned object is an instance of the
"Net::DBus::Binding::Iterator" class.
$boolean = $msg->get_no_reply()
Gets the flag indicating whether the message is expecting a reply to
be sent.
$msg->set_no_reply($boolean)
Toggles the flag indicating whether the message is expecting a reply
to be sent. All method call messages expect a reply by default. By
toggling this flag the communication latency is reduced by removing
the need for the client to wait
my @values = $msg->get_args_list
De-marshall all the values in the body of the message, using the
message signature to identify data types. The values are returned as
a list.
$msg->append_args_list(@values)
Append a set of values to the body of the message. Values will be
encoded as either a string, list or dictionary as appropriate to
their Perl data type. For more specific data typing needs, the
Net::DBus::Binding::Iterator object should be used instead.
my $sig = $msg->get_signature
Retrieves a string representing the type signature of the values
packed into the body of the message.
