However, this means overriding a private method!

Surely by definition, if you can override a method it isn't private :-)

That's not to say that private methods are useless, but I would want to see a more pertinent example before I could comment on how you are using it.

Where "private" methods win is when you want to hide your implementation decisions from subclasses. If you call your method as $self->_whatever you leave yourself open to having your code broken if a subclass adds its own _whatever method.

You can also break existing code if you add a _something_else method to a later version of your base class when a subclass already has a method of the same name.

Using lexically scoped coderefs or alternate calling strategies means we can code safe in the knowledge that a subclass is not going to change the intended behaviour of our "private" implementation methods.

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.
