perl 传递对象到模块

perl 中的对象 就是引用 通过new方法传递数据结构给各个模块

[root@wx03 test]# cat x1.pm
package x1;
use Data::Dumper;
sub new {
my $self ={};
my $invocant = shift;
my $class = ref($invocant) || $invocant;
my ($name,$age,$starting_position,$monthly_salary)=@_;
      my $self = {
         "name" =>$name,
         "age" =>$age
                 };
print "\$class is $class\n";
print "--------------------\n";
print $self->{name};
print "\n";
print "--------------------\n";

bless($self, $class); # 给予对象性质
print "\$self is $self\n";
$str=Dumper($self);
print "\$str is $str\n";

return $self;
};  

sub sum_var {
  my ($self,
      $var1,              # Name or IP number of host to ping
      $var2,           # Seconds after which ping times out
      ) = @_;
my $var3= $var1 + $var2;
return $var3;
 }
1;

[root@wx03 test]# cat a2.pl
unshift(@INC,"/root/test");
require x1;
$ed=x1->new('lily','29');
print "\n";

[root@wx03 test]# perl a2.pl
$class is x1
--------------------
lily
--------------------
$self is x1=HASH(0xd49310)  ###perl里对象就是hash
$str is $VAR1 = bless( {
                 'name' => 'lily',
                 'age' => '29'
               }, 'x1' );
