The features it provides have been added to the Moose core code as Moose::Meta::Attribute::Native. This distribution should not be used by any new code.\fR .PP While Moose attributes provide you with a way to name your accessors, readers, writers, clearers and predicates, this library provides commonly used attribute helper methods for more specific types of data. .PP As seen in the \*(L"\s-1SYNOPSIS\*(R"\s0, you specify the extension via the \&\f(CW\*(C`metaclass\*(C'\fR parameter. Available meta classes are: .SH "PARAMETERS" .IX Header "PARAMETERS" .SS "provides" .IX Subsection "provides" This points to a hashref that uses \f(CW\*(C`provider\*(C'\fR for the keys and \&\f(CW\*(C`method\*(C'\fR for the values. The method will be added to the object itself and do what you want. .SS "curries" .IX Subsection "curries" This points to a hashref that uses \f(CW\*(C`provider\*(C'\fR for the keys and has two choices for the value: .PP You can supply \f(CW\*(C`{method => [ @args ]}\*(C'\fR for the values. The method will be added to the object itself (always using \f(CW@args\fR as the beginning arguments). .PP Another approach to curry a method provider is to supply a coderef instead of an arrayref. The code ref takes \f(CW$self\fR, \f(CW$body\fR, and any additional arguments passed to the final method. .PP .Vb 1 \& # ... \& \& curries => { \& grep => { \& times_with_day => sub { \& my ($self, $body, $datetime) = @_; \& $body\->($self, sub { $_\->ymd eq $datetime\->ymd }); \& } \& } \& } \& \& # ... \& \& $obj\->times_with_day(DateTime\->now); # takes datetime argument, checks day .Ve .SH "METHOD PROVIDERS" .IX Header "METHOD PROVIDERS" .IP "Number" 4 .IX Item "Number" Common numerical operations. .IP "String" 4 .IX Item "String" Common methods for string operations. .IP "Counter" 4 .IX Item "Counter" Methods for incrementing and decrementing a counter attribute. .IP "Bool" 4 .IX Item "Bool" Common methods for boolean values. .IP "Collection::Hash" 4 .IX Item "Collection::Hash" Common methods for hash references. .IP "Collection::ImmutableHash" 4 .IX Item "Collection::ImmutableHash" Common methods for inspecting hash references. .IP "Collection::Array" 4 .IX Item "Collection::Array" Common methods for array references. .IP "Collection::List" 4 .IX Item "Collection::List" Common list methods for array references. .SH "DEPRECATION NOTICE" .IX Header "DEPRECATION NOTICE" The functionality in this family of modules is now implemented in the Moose core as Moose::Meta::Attribute::Native.
