How do I implement a dispatch table in a Perl OO module?
- by Iain
I want to put some subs that are within an OO package into an array - also within the package - to use as a dispatch table. Something like this
package Blah::Blah;
use fields 'tests';
sub new {
my($class )= @_;
my $self = fields::new($class);
$self->{'tests'} = [
$self->_sub1
,$self->_sub2
];
return $self;
}
_sub1 { ... };
_sub2 { ... };
I'm not entirely sure on the syntax for this?
$self->{'tests'} = [
$self->_sub1
,$self->_sub2
];
or
$self->{'tests'} = [
\&{$self->_sub1}
,\&{$self->_sub2}
];
or
$self->{'tests'} = [
\&{_sub1}
,\&{_sub2}
];
I don't seem to be able to get this to work within an OO package, whereas it's quite straightforward in a procedural fashion, and I haven't found any examples for OO.
Any help is much appreciated,
Iain
