=head1 NAME

Net::DBus::Binding::Message::MethodCall - a message encoding a method call

=head1 DESCRIPTION

This module is part of the low-level DBus binding APIs, and
should not be used by application code. No guarentees are made
about APIs under the C<Net::DBus::Binding::> namespace being
stable across releases.

This module provides a convenience constructor for creating
a message representing a method call.

package Net::DBus::Binding::Message::MethodCall;

use 5.006;
use strict;

use Net::DBus;
use base qw(Exporter Net::DBus::Binding::Message);

=item my $call = Net::DBus::Binding::Message::MethodCall->new(
  service_name => $service, object_path => $object, 
  interface => $interface, method_name => $name);

Create a message representing a call on the object located at
the path C<object_path> within the client owning the well-known
name given by C<service_name>. The method to be invoked has
the name C<method_name> within the interface specified by the
C<interface> parameter.
