Method modifiers are a powerful feature from the CLOS (Common Lisp
|
||
|
|
Object System) world.
|
||
|
|
|
||
|
|
In its most basic form, a method modifier is just a method that
|
||
|
|
calls $self->SUPER::foo(@_). I for one have trouble remembering
|
||
|
|
that exact invocation, so my classes seldom re-dispatch to their
|
||
|
|
base classes. Very bad!
|
||
|
|
|
||
|
|
Class::Method::Modifiers provides three modifiers: before, around,
|
||
|
|
and after. before and after are run just before and after the method
|
||
|
|
they modify, but can not really affect that original method. around
|
||
|
|
is run in place of the original method, with a hook to easily call
|
||
|
|
that original method. See the MODIFIERS section for more details
|
||
|
|
on how the particular modifiers work.
