NAME

       Net::DBus::Binding::Message - Base class for messages

SYNOPSIS

       Sending a message

         my $msg = new Net::DBus::Binding::Message::Signal;
         my $iterator = $msg->iterator;

         $iterator->append_byte(132);
         $iterator->append_int32(14241);

         $connection->send($msg);

DESCRIPTION

       Provides a base class for the different kinds of message that can be sent/received.
       Instances of this class are never instantiated directly, rather one of the four sub-types
       Net::DBus::Binding::Message::Signal, Net::DBus::Binding::Message::MethodCall,
       Net::DBus::Binding::Message::MethodReturn, Net::DBus::Binding::Message::Error should be
       used.

CONSTANTS

       The following constants are defined in this module. They are not exported into the

           data type.

           data type.

       TYPE_INT64

           data type.

       TYPE_OBJECT_PATH
           Constant representing the signature value associated with the object path data type.

       TYPE_STRING
           Constant representing the signature value associated with the UTF-8 string data type.

       TYPE_SIGNATURE
           Constant representing the signature value associated with the signature data type.

       TYPE_STRUCT
           Constant representing the signature value associated with the struct data type.

       TYPE_UINT16
           Constant representing the signature value associated with the unsigned 16 bit integer
           data type.

       TYPE_UINT32
           Constant representing the signature value associated with the unsigned 32 bit integer
           data type.

       TYPE_UINT64
           Constant representing the signature value associated with the unsigned 64 bit integer
           data type.

       TYPE_VARIANT
           Constant representing the signature value associated with the variant data type.

METHODS

       my $msg = Net::DBus::Binding::Message->new(message => $rawmessage);
           Creates a new message object, initializing it with the underlying C message object
           given by the "message" object. This constructor is intended for internal use only,
           instead refer to one of the four sub-types for this class for specific message types

       my $type = $msg->get_type
           Retrieves the type code for this message. The returned value corresponds to one of the
           four "Net::DBus::Binding::Message::MESSAGE_TYPE_*" constants.

       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 uniqe 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 guarenteed 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.

       my $sig = $msg->get_signature
           Retrieves a string representing the type signature of the values packed into the body
           of the message.

       $msg->set_sender($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.
