Hi,

I am a novice to Moose and am stuck to a code which might be very trivial.

I am using handles to delegate few subroutines but I do want to have a common code for exception handling around them. My problem is that I want to throw different exceptions for different subroutines.

Please refer the code below:

has 'usr_manager' => (
    is => 'rw',
    isa => 'UserManager',
    lazy_build => 1,
    handles => {
        list_users => 'list',
        load_user  => 'load',
    },
);
has 'prod_manager' => (
    is => 'rw',
    isa => 'ProductManager',
    lazy_build => 1,
    handles => {
        list_prods => 'list',
        load_prod  => 'load',
    },
);
around qw(list_users load_user list_prods load_prod) => sub {
    my $orig = shift;
    my $self = shift;

    my $return_data;
    eval {
        $return_data = $self->$orig(@_);
    };
    if (my $E = Exception::Class->caught('MyExeption')) {
        $E->rethrow();
    }
    if ($@) {
        my $message = $self->truncate_err_msg($@);
        #Throw exception based on subroutine.
    }
    return $return_data;
};

I tried passing extra parameter from handles (as in the example below) but its not it’s not passed to around.

has 'prod_manager' => (
    is => 'rw',
    isa => 'ProductManager',
    lazy_build => 1,
    handles => {
        list_prods => ['list' => 'Execption1'],
        load_prod  => ['load' => 'Execption2'],
    },
);

I can handle the exception inside the delegated subroutine but would like to do it at this one place as it changes will be at only one place.

Thanks in advance for any information/help you can provide.
