I have an object with a method that returns references to other methods on that object. I need to call those methods with parameters.
foo.pl
#!/usr/bin/perl
use strict; use warnings; use Data::Dumper;
use Foo;
my $help = 'Please display this message';
my $foo = Foo->new;
my $subref = $foo->subref;
foreach my $pos (@{$subref->{order}}){
print "POS: $pos\n";
my $sub = $subref->{dispatch}->{$pos};
print Dumper($sub);
&$sub($help);
}
Foo.pm
package Foo;
use strict; use warnings;
sub new { bless {}, shift; }
sub suba
{
my $self = shift;
my $param = shift || '';
print "Message is: $param\n";
}
sub subb { return; }
sub subref
{
my $self = shift;
return {
order => ['A', 'B'],
dispatch => {
A => sub { $self->suba },
B => sub { $self->subb },
}
};
}
1;
> perl foo.pl
POS: A
$VAR1 = sub { "DUMMY" };
Message is:
POS: B
$VAR1 = sub { "DUMMY" };

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

Want more info? How to link
or How to display code and escape characters
are good places to start.
