I am making my first steps with Object Oriented Perl, and I am afraid a have a pretty newbie question. Using Moose, I made the following class:

package MSOOMoose;


use Moose;


has 'query' => (
    is => 'rw',
    isa => 'Str'
);
has 'commit' => (
    is => 'rw',
    isa => 'Int'
);
has 'insertcount' => (
    is => 'rw',
    isa => 'Int'
);



sub setQuery
{
    my $self = shift;
    my $value = shift;
    $self->{query} = $value;
}


sub committoDB
{
    my $self = shift;
    print "Dit is subroutine: committoDB\n";
    
    # RESET COUNTER
    #$self->{insertcount} = 0;
    print $self->insertcount, "***\n";
}


sub insertQuery
{
    my $self = shift;
    my $commitvalue = shift;
    $self->{insertcount} += 1;
    my $counter = $self->insertcount;
    print "Count: $counter\tInsertQuery: ", $self->query, "\n";
    # ADD TO HASH: FOR LATER
    if (defined($commitvalue) && ($commitvalue == 1))
    {
        print "Yes, commit! Commitvalue = $commitvalue\n";
        committoDB;
    }
    elsif ($counter == $self->commit)
    {
        committoDB;
    }
}


no Moose;

And here's my program calling it:

#!/usr/bin/perl -w


use strict;
use warnings;


use MSOOMoose;

my $sqlsyntax;


my $msoo = MSOOMoose->new(
    commit => 5
);


$msoo->setQuery("INSERT INTO groupinsert (number) VALUES ('2')");
$msoo->insertQuery(1); # 1 means: force commit


for ($a = 0; $a < 10; $a += 1)
{
    $sqlsyntax = qq{INSERT INTO groupinsert (number) VALUES ('$a')};
    $msoo->setQuery($sqlsyntax);
    $msoo->insertQuery();
    
}


exit(0);

I get an error saying: "Can't call method "insertcount" on an undefined value at MSOOMoose.pm line 45." This is the last line in the sub committoDB.

How can I get the value of insertcount in this methode? It looks like 'insertcount' is not in my namespace here.

The objective is to create a database module in where I can force commits to the database, or after a certain amount of inserts. But mostly, I am just trying to understand OO in Perl.

Any help will be much appreciated!

And a link to something like Moose for dummies too. :-)
