=head1 NAME

NACL::Events::C_STask - Base branch event class for all events published by NACL
component or STask method invocations

=head1 DESCRIPTION

C<NACL::Events::C_STask> event class can be used for subscribing to all events published by NACL 
component and STask method invocations. This event class can be used only for subscribing not
for publishing any events. This library extends the functionality of C<NACL::Evetns::C_STask>


=head1 SYNOPSIS

The following example will illustrate on how to subscribe to all NACL events

 use NATE::Log qw(log_global);
 use NATE::Events qw(eventloop_drain);

 use NACL::Events::C_STask;;
 my $event = NACL::Events::C_STask->new();

 # subscribe to all NACL events and execute the callback when it occurs
 my $listener = $event->subscribe(listener => {
                                      callback => \&event_handler,
                                      flag  => 0
                                  });

 sub event_handler {
     my $msg_obj = shift;
     my $local_listener = shift;

     if ($msg_obj->topic() eq "NACL::Events::C_STask::Foo::create") {
         log_global()->comment("An element Foo was created");
     } elsif ($msg_obj->topic() eq "NACL::Events::C_STask::Foo::delete") {
         log_global()->comment("An element Foo was deleted");
         # update the flag on the listener hash reference to break the eventloop_drain
         $local_listener->{flag} = 1;
     } elsif  {
         ..
     }
     ..
 }

 while (!$listener->{flag}) {
     # do other things in the mean time ...
     eventloop_drain();
 }
