178
179					=head1 DESCRIPTION
180
181					This class lets you build groups of accessors that will call different
182					getters and setters. The documentation of this module still requires a lot
183					of work (B<< volunteers welcome >.> >>), but in the meantime you can refer to
184					L<this post\|http://lo-f.at/glahn/2009/08/WritingPowerfulAccessorsForPerlClasses.html>
185					for more information.
186
187					=head2 Notes on accessor names
188
189					In general method names in Perl are considered identifiers, and as such need to
190					conform to the identifier specification of C<qr/\A[A-Z_a-z][0-9A-Z_a-z]*\z/>.
191					While it is rather easy to invoke methods with non-standard names
192					(C<< $obj->${\"anything goes"} >>), it is not possible to properly declare such
193					methods without the use of L<Sub::Name>. Since this module must be able to
194					function identically with and without its optional dependencies, starting with
195					version C<0.10008> attempting to declare an accessor with a non-standard name
196					is a fatal error (such operations would silently succeed since version
197					C<0.08004>, as long as L<Sub::Name> is present, or otherwise would result in a
198					syntax error during a string eval).
199
200					Unfortunately in the years since C<0.08004> a rather large body of code
201					accumulated in the wild that does attempt to declare accessors with funny
202					names. One notable perpetrator is L<DBIx::Class::Schema::Loader>, which under
203					certain conditions could create accessors of the C<column> group which start
204					with numbers and/or some other punctuation (the proper way would be to declare
205					columns with the C<accessor> attribute set to C<undef>).
206
207					Therefore an escape mechanism is provided via the environment variable
208					C<CAG_ILLEGAL_ACCESSOR_NAME_OK>. When set to a true value, one warning is
209					issued B<per class> on attempts to declare an accessor with a non-conforming
210					name, and as long as L<Sub::Name> is available all accessors will be properly
211					created. Regardless of this setting, accessor names containing nulls C<"\0">
212					are disallowed, due to various deficiencies in perl itself.
213
214					If your code base has too many instances of illegal accessor declarations, and
215					a fix is not feasible due to time constraints, it is possible to disable the
216					warnings altogether by setting C<$ENV{CAG_ILLEGAL_ACCESSOR_NAME_OK}> to
217					C<DO_NOT_WARN> (observe capitalization).

233					Creates a set of accessors in a given group.
234
235					$group is the name of the accessor group for the generated accessors; they
236					will call get_$group($field) on get and set_$group($field, $value) on set.
237
238					If you want to mimic Class::Accessor's mk_accessors $group has to be 'simple'
239					to tell Class::Accessor::Grouped to use its own get_simple and set_simple
240					methods.
241
242					@fieldspec is a list of field/accessor names; if a fieldspec is a scalar
243					this is used as both field and accessor name, if a listref it is expected to
244					be of the form [ $accessor, $field ].

581					accessors if this module is available on your system.

632					=head2 Notes on Class::XSAccessor
633
634					You can force (or disable) the use of L<Class::XSAccessor> before creating a
635					particular C<simple> accessor by either manipulating the global variable
636					C<$Class::Accessor::Grouped::USE_XS> to true or false (preferably with
637					L<localization\|perlfunc/local>, or you can do so before runtime via the
638					C<CAG_USE_XS> environment variable.
639
640					Since L<Class::XSAccessor> has no knowledge of L</get_simple> and
641					L</set_simple> this module does its best to detect if you are overriding
642					one of these methods and will fall back to using the perl version of the
643					accessor in order to maintain consistency. However be aware that if you
644					enable use of C<Class::XSAccessor> (automatically or explicitly), create
645					an object, invoke a simple accessor on that object, and B<then> manipulate
646					the symbol table to install a C<get/set_simple> override - you get to keep
647					all the pieces.
