( #3333=superdoc: print w/replies, xml ) Need Help??
I have the following class :
package Link; sub FETCH { my $this = shift; return $this->{"site"}; } sub STORE { my ($self,$site) = @_; $self->{"site"} = $site; } sub print_method { my $self = shift; print $self->{"site"}; } sub TIESCALAR { my $class = shift; my $link = shift; my $this = {}; bless($this,$class); $this->{"site"} = $link; return $this; } 1;
and the following code :
use Link; tie my $var,"Link",""; $var = ""; $var->print_method; print $var;
Running the code above results in a runtime error : Can't call method "print_method" without a package or object reference at line 4. . I think I understand why : when fetched , the method returns a string , which doesn't respond to "print_method" . I would like to be able to do the following things : if fetched , print the site's address , if stored , change the address . I would also like to be able to call methods on the object . I am aware that if I return $self from fetch , I will accomplish the "call methods objective" , but that will invalidate the first objective ( fetch ) . Is there a way I could accomplish all of them ?

Use:  <p> text here (a paragraph) </p>

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.
