NAME ^

Rose::ObjectX::CAF - Class::Accessor::Fast compatability for Rose::Object

SYNOPSIS ^

 package MyClass;
 use strict;
 use base qw( Rose::ObjectX::CAF );
 __PACKAGE__->mk_accessors(qw( foo bar ));
 __PACKAGE__->mk_ro_accessors(qw( color name ));
 1;

DESCRIPTION ^

Rose::ObjectX::CAF is a compatability layer for Class::Accessor::Fast users who want to migrate to Rose::Object.

As evidenced in App::Benchmark::Accessors, Rose::Object + Class::XSAccessor is much faster than Class::Accessor::Fast (and more extensible). I decided to switch over, but had a lot of code already using CAF. So this class was born to make the migration easier.

Just replace this line in your classes:

 use base qw( Class::Accessor::Fast );

with this:

 use base qw( Rose::ObjectX::CAF );

and no other changes should be necessary.

METHODS ^

new

Works like CAF, but may take a hash (the Rose::Object style) or hash ref (the CAF style).

init

Like Rose::Object, called by new(). Do not override new() in your subclasses; override init() instead. And be sure to call:

 $self->SUPER::init(@_);  # or with MRO::Compat, $self->next::method(@_);

in your subclass.

Rather than calling the method name for each param passed in new(), the value is simply set in the object as a hash ref. This assumes every object is a blessed hash ref.

The reason the hash is preferred over the method call is to support read-only accessors, which will croak if init() tried to set values with them.

mk_accessors( @list_of_method_names )

Just like CAF.

mk_ro_accessors( @list_of_method_names );

Just like CAF, for read-only (accessor/getter) methods.
