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

I have to admit that I've never cared for overloaded methods that function as both accessors and mutators, but in this case, it might make sense.

The combination of parameters can be dealt with if I pass $self to the subroutines used for validation. Then, each item can check the other values, but this could make things order dependant (untested).

my $param = Sub::ParamObject->new({ foo => qr/\d+/, bar => sub { $_[0]->{foo} > 3 && $_[1] =~ /^this|that$/ } }); $param ->foo(7) ->bar('this'); # succeeds $param ->foo(2) ->bar('this'); # fails

And thanks for the bug catch!

Cheers,
Ovid

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 How to display code and escape characters are good places to start.
