Hi, I have struggled for the whole afternoon trying to
code a perl object which also enable users to fill in
the its data member ( a hash of hash).See the purpose below. I cannot figure it out. Please help.
Class Purpose: I am using this class as a data
storage for the list of MSSQL DATABASE servers which
later one I will try to connect to then do some query
against, then verify those query results
basically, it does the following:
1. get a list of servers with credentials from other program and feed those into the object.. use default as fallback (should I?)
2. read in those data tying to that server
3. clients can add server
4. clients can delete server
5.clients can delete everything clients here mean the users of the object 
package myObject;
 
$VERSION = 1.00;
use strict;
use warnings;
use diagnostics;
use vars qw(@ISA);
@ISA = qw(Class::Singleton);

use Carp ();
$Carp::Verbose =1;
{
  my %serverMap = (
            default => {
                 ipaddress=127.0.0.1,
                 dsn=""default,
                 userid="sa",
                 password="password",
                 instance="instance"
             }, 
   );
  sub new{
     my ($self, %args) = @_;
     my %array=();
     %array = (%args); #?
     my $self={};
     return bless {$self};  
  }
 sub printMe(){
    my ($self) = @_;
    while ( ($server, $credentials) = each $self->%serverMap) {
    print "$server: ";
    while ( ($credentials, $value) = each %$roles ) {
        print "$credentials=$value ";
    }
    print "\n";
}
  }
 sub fillServerMap($){  <<<<< no idea how to input
 
   my ($self) = @_;
   for $server ( @_ ) {
        push @  <<<-- NO IDEA how to do this
    }
  }
}
 sub removeServerMap($){
 
   my ($self) = @_;
   $self->serverMap ={};
}
 sub deleteServer($){
   my ($self,$server)=@_;
    delete $self->serverMap {$server};


}
