Thanks for your reply. I guess I got it.
My understaning is that Foo->hello & hello are basically the same except the former is calling class method and passing 'Foo' to hello as the first arg, but the later is calling a subroutine and will not pass 'Foo'. How do you think?
I ask this question is because I see the following Item class generated by catalyst's create script using several _PACKAGE__->...() inside its package. I think the purpose of these class method calls is to initialize some class variables (data structures) instead of object variables for Item's parent class, which is DBIx::Class. Am I right ?
Thanks.
package Result::Item;
use strict;
use warnings;
use base 'DBIx::Class';
__PACKAGE__->load_components( "InflateColumn::DateTime", "Core" );
__PACKAGE__->table("item");
__PACKAGE__->add_columns(
"id",
{
data_type => "INTEGER",
default_value => undef,
is_nullable => 0,
size => undef,
},
);

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).
