38 "MooseX::NonMoose" allows for easily subclassing non-Moose classes with
39 Moose, taking care of the annoying details connected with doing this,
40 such as setting up proper inheritance from Moose::Object and installing
41 (and inlining, at "make_immutable" time) a constructor that makes sure
42 things like "BUILD" methods are called. It tries to be as non-intrusive
43 as possible - when this module is used, inheriting from non-Moose
44 classes and inheriting from Moose classes should work identically,
45 aside from the few caveats mentioned below. One of the goals of this
46 module is that including it in a Moose::Exporter-based package used
47 across an entire application should be possible, without interfering
48 with classes that only inherit from Moose modules, or even classes that
49 don't inherit from anything at all.
50 There are several ways to use this module. The most straightforward is
52 to just "use MooseX::NonMoose;" in your class; this should set up
53 everything necessary for extending non-Moose modules.
54 MooseX::NonMoose::Meta::Role::Class and
55 MooseX::NonMoose::Meta::Role::Constructor can also be applied to your
56 metaclasses manually, either by passing a "-traits" option to your "use
57 Moose;" line, or by applying them using Moose::Util::MetaRole in a
58 Moose::Exporter-based package. MooseX::NonMoose::Meta::Role::Class is
59 the part that provides the main functionality of this module; if you
60 don't care about inlining, this is all you need to worry about.
61 Applying MooseX::NonMoose::Meta::Role::Constructor as well will provide
62 an inlined constructor when you immutabilize your class.
63 "MooseX::NonMoose" allows you to manipulate the argument list that gets
65 passed to the superclass constructor by defining a "FOREIGNBUILDARGS"
66 method. This is called with the same argument list as the "BUILDARGS"
67 method, but should return a list of arguments to pass to the superclass
68 constructor. This allows "MooseX::NonMoose" to support superclasses
69 whose constructors would get confused by the extra arguments that Moose
70 requires (for attributes, etc.)
71 Not all non-Moose classes use "new" as the name of their constructor.
73 This module allows you to extend these classes by explicitly stating
74 which method is the constructor, during the call to "extends". The
75 syntax looks like this:
76 extends 'Foo' => { -constructor_name => 'create' };
78 similar to how you can already pass "-version" in the "extends" call in
80 a similar way.
81
83 • The reference that the non-Moose class uses as its instance type
84 must match the instance type that Moose is using. Moose's default
85 instance type is a hashref, but other modules exist to make Moose
86 use other instance types. MooseX::InsideOut is the most general
87 solution - it should work with any class. For globref-based classes
88 in particular, MooseX::GlobRef will also allow Moose to work. For
89 more information, see the "032-moosex-insideout" and
90 "033-moosex-globref" tests bundled with this dist.
91 • Modifying your class' @ISA after an initial "extends" call will
93 potentially cause problems if any of those new entries in the @ISA
94 override the constructor. "MooseX::NonMoose" wraps the nearest
95 "new()" method at the time "extends" is called and will not see any
96 other "new()" methods in the @ISA hierarchy.
97 • Completely overriding the constructor in a class using
99 "MooseX::NonMoose" (i.e. using "sub new { ... }") currently doesn't
100 work, although using method modifiers on the constructor should
101 work identically to normal Moose classes.
