=head1 SYNOPSIS

Please keep in mind that PID is not a requirement and if not specified is set to 0,
meaning it will show up earlier.

=head1 METHODS

=head2 new

This initiates the module.

No arguments are taken and this will always succeed.

    my $sorter=$sorter=Net::Connection::Sort::uid->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';
	}

	# whoops... just realized I forgot to create a method for this in Net::Connection... doing it this way foreign
	# compatibility with Net::Connection 0.0.0 as of currently
	@objects=sort  {
		&helper( $a->{pid} ) <=>  &helper( $b->{pid} )
	} @objects;

	return @objects;
}

=head2 helper

This is a internal function.

If no PID is defined, returns 0.

=cut

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