NAME

Krang::MethodMaker - extended version of Class::MethodMaker

SYNOPSIS

  # create a readonly foo_id() accessor and standard accessor/mutators
  # title() and url().  Create standard accessor/mutators itchy() and
  # scratchy() that trigger calls to _notify() when set.
  use Krang::ClassLoader MethodMaker => 
    get     => ['foo_id'],
    get_set => ['title', 'url'],
    get_set_with_notify => { method => '_notify',
                             attr   => ['itchy', 'scratchy'] };

  # catch changes to itchy and scratchy
  sub _notify {
    my ($self, $which, $old, $new) = @_;
    # ...
  }

DESCRIPTION

This class extends Class::MethodMaker for use by Krang. All the normal Class::MethodMaker generators are available from Krang::MethodMaker, with a few changes.

When we identify repeated code patterns we should consider adding a method generator to this class.

INTERFACE

• get_set
  
Instead of defaulting to producing foo() and foo_clear(), Krang's get_set takes none of the ``flavor'' options (-java, etc) and always behaves as though -noclear were used.

Also, the code generated is faster than the default Class::MethodMaker code since it doesn't use lexicals.

• get_set_with_notify
  
Works like get_set, but after set operations calls the specified method with three parameters - the attribute which changed, the old value and the new value.

Takes a list of hashes with two keys - method and attr.

• get
  
Supplies just the get side of a get/set accessor. This is useful for readonly attributes, like object IDs. These values will only be mutable by setting the underlying hash key.

TODO

• Write faster replacement for Class::MethodMaker::list() methods.
