Class::Smart - (former Class::AutoArgs) |
| 20 |
|
| 21 |
|
| 22 |
=head1 Description |
| 23 |
|
| 24 |
Includes little constructor which introduces |
| 25 |
passed in argument list as object attributes. |
| 26 |
|
| 27 |
Note: Since this list is automagically coerced to a |
| 28 |
hash by perl itself, it is assumed to have |
| 29 |
an even number of elements. Perl will croak |
| 30 |
otherwise. |
| 31 |
|
| 32 |
|
| 33 |
=head1 Todo |
| 34 |
|
| 35 |
o Handle strategy/behavior for odd number of elements inside argument list. |
| 36 |
(This code is already established somewhere and gets used almost |
| 37 |
everywhere throughout CPAN in various ways: see Perl: There is more |
| 38 |
then one way to do it. - Please look at XML::XUpdate::XSLT::__read_arguments...) |
