This delegates methods on the object (class ObjectContent) to the the underlying object.

It is ruby std-lib, so I'm thinking that a link to the docs isn't really called for: http://www.ruby-doc.org/stdlib-1.9.3/libdoc/delegate/rdoc/SimpleDelegator.html

Basically there is delegated.__setobj__(object) and object = delegated.__getobj__ to access the underlying object and it just let's you call through.
