NAME

       Net::DBus::Object - Implement objects to export to the bus

SYNOPSIS

         # Connecting an object to the bus, under a service
         package main;

         use Net::DBus;

         # Attach to the bus
         my $bus = Net::DBus->find;

         # Acquire a service 'org.demo.Hello'
         my $service = $bus->export_service("org.demo.Hello");

         # Export our object within the service
         my $object = Demo::HelloWorld->new($service);

         ....rest of program...

         # Define a new package for the object we're going
         # to export
         package Demo::HelloWorld;

         # Specify the main interface provided by our object
         use Net::DBus::Exporter qw(org.example.demo.Greeter);

         # We're going to be a DBus object
         use base qw(Net::DBus::Object);

         # Export a 'Greeting' signal taking a stringl string parameter
         dbus_signal("Greeting", ["string"]);

         # Export 'Hello' as a method accepting a single string
         # parameter, and returning a single string value
         dbus_method("Hello", ["string"], ["string"]);

         sub new {
             my $class = shift;
             my $service = shift;
             my $self = $class->SUPER::new($service, "/org/demo/HelloWorld");

             bless $self, $class;

             return $self;
         }

         sub Hello {
           my $self = shift;
           my $name = shift;

           $self->emit_signal("Greeting", "Hello $name");
           return "Said hello to $name";
         }

         # Export 'Goodbye' as a method accepting a single string
         # parameter, and returning a single string, but put it
         # in the 'org.exaple.demo.Farewell' interface

         dbus_method("Goodbye", ["string"], ["string"], "org.example.demo.Farewell");

         sub Goodbye {
           my $self = shift;
           my $name = shift;

           $self->emit_signal("Greeting", "Goodbye $name");
           return "Said goodbye to $name";
         }

DESCRIPTION

       This the base for implementing objects which are directly exported to the bus. The methods
       implemented in a subclass are mapped to methods on the bus. By using this class, an
       application is directly tieing the RPC functionality into its object model. Applications
       may thus prefer to use the "Net::DBus::ProxyObject" class which allows the RPC
       functionality to be maintained separately from the core object model, by proxying RPC
       method calls.

METHODS

       my $object = Net::DBus::Object->new($service, $path)
           This creates a new DBus object with an path of $path registered within the service
           $service. The $path parameter should be a string complying with the usual DBus
           requirements for object paths, while the $service parameter should be an instance of
           Net::DBus::Service.  The latter is typically obtained by calling the "export_service"
           method on the Net::DBus object.

       my $object = Net::DBus::Object->new($parentobj, $subpath)
           This creates a new DBus child object with an path of $subpath relative to its parent
           $parentobj. The $subpath parameter should be a string complying with the usual DBus
           requirements for object paths, while the $parentobj parameter should be an instance of
           Net::DBus::BaseObject or a subclass.
