Catalyst::DispatchType::Path - Path DispatchType
=head1 SYNOPSIS
See L<Catalyst::DispatchType>.
=head1 DESCRIPTION
Dispatch type managing full path matching behaviour. For more information on
dispatch types, see:
=over 4
=item * L<Catalyst::Manual::Intro> for how they affect application authors
=item * L<Catalyst::DispatchType> for implementation information.

=head1 METHODS
=head2 $self->list($c)
Debug output for Path dispatch points
=cut

=head2 $self->match( $c, $path )
For each action registered to this exact path, offers the action a chance to
match the path (in the order in which they were registered). Succeeds on the
first action that matches, if any; if not, returns 0.
=cut
sub match {
my ( $self, $c, $path ) = @_;

$c->req->match($path);
$c->action($action);
$c->namespace( $action->namespace );
return 1;
}
return 0;
}
=head2 $self->register( $c, $action )
Calls register_path for every Path attribute for the given $action.
=cut
sub register {
my ( $self, $c, $action ) = @_;
my @register = @{ $action->attributes->{Path} || [] };
$self->register_path( $c, $_, $action ) for @register;
return 1 if @register;
return 0;
}
=head2 $self->register_path($c, $path, $action)
Registers an action at a given path.
=cut

sort { $a->compare($b) } ($action, @{ $self->_paths->{$path} || [] })
];
return 1;
}
=head2 $self->uri_for_action($action, $captures)
get a URI part for an action; always returns undef is $captures is set
since Path actions don't have captures
=cut
