%description
|
|
Method modifiers are a convenient feature from the CLOS (Common Lisp Object
|
|
System) world.
|
|
|
|
In its most basic form, a method modifier is just a method that calls
|
|
'$self->SUPER::foo(@_)'. I for one have trouble remembering that exact
|
|
invocation, so my classes seldom re-dispatch to their base classes. Very
|
|
bad!
|
|
|
|
'Class::Method::Modifiers' provides three modifiers: 'before', 'around',
|
|
and 'after'. 'before' and 'after' are run just before and after the method
|
|
they modify, but can not really affect that original method. 'around' is
|
|
run in place of the original method, with a hook to easily call that
|
|
original method. See the MODIFIERS section for more details on how the
|
|
particular modifiers work.
|
|
|
|
One clear benefit of using 'Class::Method::Modifiers' is that you can
|
|
define multiple modifiers in a single namespace. These separate modifiers
|
|
don't need to know about each other. This makes top-down design easy. Have
|
|
a base class that provides the skeleton methods of each operation, and have
|
|
plugins modify those methods to flesh out the specifics.
|
|
|
|
Parent classes need not know about 'Class::Method::Modifiers'. This means
|
|
you should be able to modify methods in _any_ subclass. See
|
|
Term::VT102::ZeroBased for an example of subclassing with
|
|
'Class::Method::Modifiers'.
|
|
|
|
In short, 'Class::Method::Modifiers' solves the problem of making sure you
|
|
call '$self->SUPER::foo(@_)', and provides a cleaner interface for it.
|
|
|
|
As of version 1.00, 'Class::Method::Modifiers' is faster in some cases than
|
|
Moose. See _benchmark/method_modifiers.pl_ in the Moose distribution.
|
|
|
|
'Class::Method::Modifiers' also provides an additional "modifier" type,
|
|
'fresh'; see below.
