=head1 DESCRIPTION |
58
|
|
|
|
|
|
|
|
59
|
|
|
|
|
|
|
Rules of this class can match arbitrarily complex values. This should be used |
60
|
|
|
|
|
|
|
only when there is no other recourse, because there's no way we can inspect |
61
|
|
|
|
|
|
|
how things match. |
62
|
|
|
|
|
|
|
|
63
|
|
|
|
|
|
|
You're much better off creating a custom subclass of L<Path::Dispatcher::Rule> |
64
|
|
|
|
|
|
|
if at all possible. |

|
|
|
|
A coderef that returns C<undef> if there's no match, otherwise a list of |
71
|
|
|
|
|
|
|
strings (the results). |
72
|
|
|
|
|
|
|
|
73
|
|
|
|
|
|
|
The coderef receives the path object as its argument, and the path string as |
74
|
|
|
|
|
|
|
C<$_>. |
