Catalyst::Plugin::Observe - Observe Engine Events
use Catalyst qw[Observe];
# register the observer method as a callback to prepare_path
MyApp->add_subscriber( 'prepare_path', \&observer );
# write callback to describe what happened
sub observer {
my ( $c, $event, @args ) = @_;
$c->log->info( "observed " . $event . " with arguments " . join( '\n', @args ) );
}
Observe Engine events, for debugging purposes. Subclasses Class::Publisher.
Catalyst::Plugin::Observe allows you to register your own callbacks to specific Engine events (method calls), and to be notified through the callback when they occur. When the Engine calls the event, your callback will be called with the same arguments, which you can then display (etc.) as necessary.
$eventThe Engine event to which the callback is registered. See "OBSERVABLE EVENTS" below.
@argsThe arguments passed to the Engine event.
Class::Publisher, Catalyst::Dispatch, Catalyst::Engine.
