In the first instance you might want to look at perlboot and perltoot as they both cover Inheritance.

As to adding methods to a class at runtime, yes that is entirely possible (you will find a number of modules that do this in a sub AUTOLOAD,) but you might want to carefully review your design as it is probably not the best solution in the general case.

However if you really insist on adding methods dynamically you can do something as simple as:

package Foo; + sub new { my ( $class ) = @_; return bless {}, $class; } + package main; + use strict; + my $foo = Foo->new(); + *Foo::zub = sub { print "I'm zub!\n"; }; + $foo->zub();

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
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 or How to display code and escape characters are good places to start.
