Detailed Description

template<class T>
class matador::object_ptr< T >

The object_ptr holds a pointer to an serializable.

Template Parameters

T	The type of the serializable.

The object_ptr holds a pointer to an object. The object_ptr is a wrapper class for the object class It has a reference count mechanism. The objects inserted into the object_store are returned as a object_ptr and should be used through the object_ptr class.
