( [id://3333]=superdoc: print w/replies, xml ) Need Help??
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, }, ); 1;

to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • 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.
