hi, i am trying to take out the commonly used code from a probject and make it usable to other projects as well. they are basically utility modules. the way ii have done it is to have a wrapper module that provide access to all the other utility modules. here is a simplified version. then i simple access the wrapper module for all utility methods.

following are a simple verison and i would like to get some opinion from someone with more OO experience.

here is how I will call my utility methods in CGI::Application controller. i like it this way because i will have access to the utility methods by simple $self->sis->method call.

package MyApp::ControllerOne;
use base 'MyApp::Base';

$self->sis->add_event("event name");
$self->sis->log_event("message");
$self->sis->uuid();

package MyApp::Base;
use base 'CGI::Application';
 
sub sis {
    my $self = shift;
    unless ( $self->{__sis} ) {
        $self->{__sis} = Company::Dept->new($dbh, $uname);
    }
    return $self->{__sis};
}

here is a wrapper module to all the other utility modules:

package Company::Dept;

sub new {
    my $class = shift;
    my $self = {};
    my ($dbh, $uname) = @_;
    $self->{ __dbh } = $dbh;
    $self->{ __uname } $uname;
    bless ($self, $class);
    return $self;
}

sub log_event {
    my ($self, $msg) = @_
    unless ( $self->{__elog} ) {
        $self->{__elog} = Company::Dept::EventLogging->new( $self->dbh
+, $self->uuid ) ;
    }
    $self->{__elog}->log_event( $msg );
}    

sub add_event {
    my ($self, $msg) = @_
    unless ( $self->{__elog} ) {
        $self->{__elog} = Company::Dept::EventLogging->new($self->dbh,
+ $self->uuid ) ;
    }
    $self->{__elog}->add_event( $msg );
}

sub uuid { 
    my $self = shift;
    unless ( $self->{__uuid} ) {
        $self->{__uuid} = Company::Dept::UUID->uuid($self->dbh, $uuid 
+) ;
    }
    return $self->{__uuid} ;
}

sub dbh { return $self->{__dbh} }
sub uname {return $self->{__uname}  }

here is utility module:

package Company::Dept::EventLogging;

sub add_event { }
sub log_event { }

package Company::Dept::AnotherUtilityModule;

sub aaa { }
sub bbb {}

UPDATE: fixed the sub sis.
