NAME Hash::Objectify - Create objects from hashes on the fly VERSION version 0.002 SYNOPSIS use Hash::Objectify; # turn a hash reference into an object with accessors $object = objectify { foo => 'bar', wibble => 'wobble' }; print $object->foo; # objectify with a specific class name $object = objectify { foo => 'bar' }, "Foo::Response"; print ref $object; # "Foo::Response" DESCRIPTION Hash::Objectify turns a hash reference into a simple object with accessors for each of the keys. One application of this module could be to create lightweight response objects without the extra work of setting up an entire response class with the framework of your choice. Using Hash::Objectify is slower than accessing the keys of the hash directly, but does provide "typo protection" since a misspelled method is an error. USAGE objectify $object = objectify $hashref $object = objectify $hashref, $classname; $object->$key; # accessor $object->$key($value); # mutator The "objectify" function copies the hash reference (shallow copy), and blesses it into the given classname. If no classname is given, a meaningless, generated package name is used instead. In either case, the object will inherit from the Hash::Objectified class, which generates accessors on demand for any key in the hash. As an optimization, a generated classname will be the same for any given "objectify" call if the keys of the input are the same. (This avoids excessive accessor generation.) The first time a method is called on the object, an accessor will be dynamically generated if the key exists. If the key does not exist, an exception is thrown. Note: deleting a key *after* calling it as an accessor will not cause subsequent calls to throw an exception; the accessor will merely return undef. Objectifying with a "real" classname that does anything other than inherit from Hash::Objectified may lead to surprising behaviors from method name conflict. You probably don't want to do that. Objectifying anything other than an unblessed hash reference is an error. This is true even for objects based on blessed hash references, since the correct semantics are not universally obvious. If you really want Hash::Objectify for access to the keys of a blessed hash, you should make an explicit, shallow copy: my $copy = objectify {%$object}; SUPPORT Bugs / Feature Requests Please report any bugs or feature requests through the issue tracker at .
