The object tree as I've coded it is for converting RoseDB objects
into/from JSON and YAML via an intermediary perl hash format.
ie:
my $obj= bless { id=> 1 , __xrdbo__x=>'a' }, MyApp::Rose:: Object
my %hash= $obj->object_tree_as_hash()
my $as_json= object_tree_as_json()
my $obj= Rose::DB::Object::object_tree_from_json( $as_json );
my $obj= Rose::DB::Object::object_tree_from_hash( \%hash);
what you want sounds more like John's strip() method which is now in SVN
strip will let you serialize trees of objects , with the ability to
preserve certain things.
strip is significantly faster than the methods I'm developing -- it
just kills the bloat so you can pop an object into memcached.
my methods are designed to convert an object into something that
other languages can use-- i.e. my main application server is in Perl,
but there are certain sections that are programmed in Python and
PHP. instead of constantly loading data in multiple languages, I
have Perl ( specifically Rose ) do all of the db management , and
populate a memcached store with data that other languages consume.
