=head1 DESCRIPTION |
39
|
|
|
|
|
|
|
|
40
|
|
|
|
|
|
|
This module was created as an alternative to C |
41
|
|
|
|
|
|
|
|
42
|
|
|
|
|
|
|
Creates accessors at compiletime |
43
|
|
|
|
|
|
|
|
44
|
|
|
|
|
|
|
Have own default C method: it creates object as a blessed hash, then locks keys to defined field list, and invoke C. |
45
|
|
|
|
|
|
|
So, recommended usage inside packages, is access by hash keys (it's 3 times faster then accessor). |
46
|
|
|
|
|
|
|
Since keys are locked, you will not suffer from autovivification. Public interface recommended to be documented as accessors. |
47
|
|
|
|
|
|
|
|
48
|
|
|
|
|
|
|
Uses L |

|
=head1 METHODS |
51
|
|
|
|
|
|
|
|
52
|
|
|
|
|
|
|
All methods inherited from L. Own methods defined below |
53
|
|
|
|
|
|
|
|
54
|
|
|
|
|
|
|
=head2 new( ARGS ) |
55
|
|
|
|
|
|
|
|
56
|
|
|
|
|
|
|
Creates blessed hash, locks it keys to current fields of this package, and invoke C method with C |
57
|
|
|
|
|
|
|
|
58
|
|
|
|
|
|
|
=head2 init( ARGS ) |
59
|
|
|
|
|
|
|
|
60
|
|
|
|
|
|
|
Recommended to redefine in subclasses. Will be invoked by inherited C |
61
|
|
|
|
|
|
|
|
62
|
|
|
|
|
|
|
=head2 field_list |
63
|
|
|
|
|
|
|
|
64
|
|
|
|
|
|
|
Since this module keeps information about object fields, it can return it. |

=head1 FEATURES |
71
|
|
|
|
|
|
|
|
72
|
|
|
|
|
|
|
This module uses L, so it behaviour could be affected by L |
73
|
|
|
|
|
|
|
|
74
|
|
|
|
|

=head2 TIE [ = 0 ] |
75
|
|
|
|
|
|
|
|
76
|
|
|
|
|
|
|
Use tied hash, instead of LC<::lock_keys>. Much more slower, but could help during development. |
