your problem, i pretend, is maybe that Class::MethodMaker is an astonishing (and absurd, imho) effort to import java-think into perl. that's why for perl it's an overhead, even base.pm looks like. as you can see in the documentation from base.pm, the similarity to
package Baz;
BEGIN {
require Foo;
require Bar;
push @ISA, qw(Foo Bar);
}
is conceeded.
the thing with perl is, that everything is an agreement. every member of a class's instance
is accessible directly - however, most people consider that unattractive... so:
my $object = MyClass->new;
print $object->name;
print $object->{'name'};
are identical, provided in MyClass the 'name' method is defined. moreover, the second approach will always be a tick faster, as there is no need for dereferencing a method.
and if you really like your class to always have only one instance at the same time, try this:
package MyClass;
use strict;
use vars qw/$MUSTHAVEONLYONEINSTANCE/;
$MUSTHAVEONLYONEINSTANCE = 0;
...
sub new {
return undef if $MUSTHAVEONLYONEINSTANCE;
$MUSTHAVEONLYONEINSTANCE = 1;
...
}
sub DESTROY {
$MUSTHAVEONLYONEINSTANCE = 0;
}
unlike java, perl does'nt even try to protect you from yourself. ;)
language is a virus from outer space.
