Object::InsideOut implements inside-out objects as anonymous scalar references that are blessed into a class with the scalar containing the ID for the object (usually a sequence number). For Perl 5.8.3 and later, the scalar reference is set as *read-only* to prevent _accidental_ modifications to the ID. Object data (i.e., fields) are stored within the class's package in either arrays indexed by the object's ID, or hashes keyed to the object's ID. The virtues of the inside-out object model over the _blessed hash_ object model have been extolled in detail elsewhere. See the informational links under "SEE ALSO". Briefly, inside-out objects offer the following advantages over _blessed hash_ objects: * * Encapsulation Object data is enclosed within the class's code and is accessible only through the class-defined interface. * * Field Name Collision Avoidance Inheritance using _blessed hash_ classes can lead to conflicts if any classes use the same name for a field (i.e., hash key). Inside-out objects are immune to this problem because object data is stored inside each class's package, and not in the object itself. * * Compile-time Name Checking A common error with _blessed hash_ classes is the misspelling of field names: $obj->{'coment'} = 'Say what?'; # Should be 'comment' not 'coment' As there is no compile-time checking on hash keys, such errors do not usually manifest themselves until runtime. With inside-out objects, _text_ hash keys are not used for accessing field data. Field names and the data index (i.e., $$self) are checked by the Perl compiler such that any typos are easily caught using 'perl -c'. $coment[$$self] = $value; # Causes a compile-time error # or with hash-based fields $comment{$$self} = $value; # Also causes a compile-time error Object::InsideOut offers all the capabilities of other inside-out object modules with the following additional key advantages: * * Speed When using arrays to store object data, Object::InsideOut objects are as much as 40% faster than _blessed hash_ objects for fetching and setting data, and even with hashes they are still several percent faster than _blessed hash_ objects. * * Threads Object::InsideOut is thread safe, and thoroughly supports sharing objects between threads using threads::shared. * * Flexibility Allows control over object ID specification, accessor naming, parameter name matching, and much more. * * Runtime Support Supports classes that may be loaded at runtime (i.e., using 'eval { require ...; };'). This makes it usable from within mod_perl, as well. Also supports additions to class hierarchies, and dynamic creation of object fields during runtime. * * Exception Objects Object::InsideOut uses Exception::Class for handling errors in an OO-compatible manner. * * Object Serialization Object::InsideOut has built-in support for object dumping and reloading that can be accomplished in either an automated fashion or through the use of class-supplied subroutines. Serialization using Storable is also supported. * * Foreign Class Inheritance Object::InsideOut allows classes to inherit from foreign (i.e., non-Object::InsideOut) classes, thus allowing you to sub-class other Perl class, and access their methods from your own objects. * * Introspection Obtain constructor parameters and method metadata for Object::InsideOut classes. %prep %setup -q -n %{cpan_name}-%{version} %build perl Build.PL installdirs=vendor ./Build build flags=%{?_smp_mflags} %check ./Build test %install ./Build install destdir=%{buildroot} create_packlist=0 %perl_gen_filelist %files -f %{name}.files %defattr(-,root,root,755) %doc Changes examples README %changelog
