Hi all,
Here is my third question for the list: sometimes I want to have a subclass-
specific constant commonly implemented as a method in the subclass-hierarchy.
So I can do something like:
[code] # For demonstration - untested.
package XmlGenerator;
sub _gen_paragraph_tag
{
my $self = shift;
my $elem = shift;
my $tag_name = $self->_get_paragraph_tag_name();
$self->_start_tag($tag_name);
$self->_render_contents($elem);
$self->_end_tag($tag_name);
return;
}
package DocBook;
extends('XmlGenerator');
sub _get_paragraph_tag_name
{
return "para";
}
package HTML;
extends('XmlGenerator');
sub _get_paragraph_tag_name
{
return "p";
}
[/code]
My question is whether there's a better way to do such a thing in Moose? (Note
that it's unrelated to walkmeth - only the single, most specific, method
should be called).
I though of doing something like:
[code]
has '_get_paragraph_tag_name' => (is => 'ro', default => "para");
[/code]
And maybe specialise it further using «has '+_get_paragraph_tag_name'», but it
seems like it would be much more verbose.
Just wondering if there's a Moose best practice ("MBP", heh.) here.
