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.
