=head1 SYNOPSIS

If a local PTR could not be found or is not set, then the foreign host is used.

=head1 METHODS

=head2 new

This initiates the module.

No arguments are taken and this will always succeed.

    my $sorter=$sorter=Net::Connection::Sort::ptr_l->new;

=cut

sub new{
	my %args;
	if(defined($_[1])){
		%args= %{$_[1]};
	};


	my $self = {
				};
    bless $self;

	return $self;
}

=head2 sort

This sorts the array of Net::Connection objects.

One object is taken and that is a array of objects.

    @objects=$sorter->sorter( \@objects );

    print Dumper( \@objects );

=cut

sub sorter{
	my $self=$_[0];
	my @objects;
	if (
		defined( $_[1] ) &&
		( ref($_[1]) eq 'ARRAY' )
		){
		@objects=@{ $_[1] };
	}else{
		die 'The passed item is either not a array or undefined';
	}

	@objects=sort  {
		&helper( $a ) cmp  &helper( $b )
	} @objects;

	return @objects;
}

=head2 helper

This is a internal function.

If the local PTR is not defined, the local host is returned.

=cut

sub helper{
        if (
			( !defined($_[0]->local_ptr ) )
			){
			return $_[0]->local_host;
        }
        return $_[0]->local_ptr;
}
