Detailed Description

template<class T>
class ixion::no_free_dynamic_ref< T >

An object that acts like a reference-counted pointer to an object. However, the referenced object is not freed if the no_free_ref is the last reference to the object to go out of scope.

This is useful to pass objects allocated e.g. on the stack along inside ref's, while making sure they aren't freed. (which would most probably lead to disaster)

no_free_ref's are mostly a hack, but there are situations where you cannot avoid them. But even so, you should try not to use them where possible.

The corresponding reference_manager is identified explicitly.
