77 // * The PacketImpl destructor will *explicitly* clean-up the interpreters_ list by removing
78 // each element from the list and deleting it if it's (intrusive) refcount is 0
79 // * The PacketInterpreters use safe hooks -> they know whether they are part of a list or not
80 // * PacketHandle has an intrusive_ptr to PacketInterpreterBase. The intrusive_ptr_add_ref
81 // will refcount both the PacketImpl as well as the PacketInterpreterBase
82 // * intrusive_ptr_remove will only delete the object if it's not in a container
83 // * removing an object from the list will decrement the PacketImpl refcount accordingly
84 // * inserting an object into the list will increment the PacketImpl refcount accordingly
85 // * each PacketInterpreterBase instance holds a *raw* pointer to the PacketImpl
87 // The following operations change refcounts:
89 // * intrusive_ptr_add_ref(PacketInterpreterBase *);
90 // * intrusive_ptr_remove(PacketInterpreterBase *);
91 // * PacketImpl::appendInterpreter();
92 // * PacketImpl::prependInterpreter();
93 // * PacketImpl::truncateInterpreters();

96 // PacketInterpreterBase::assign/release
