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

93 // * PacketImpl::appendInterpreter();
94 // * PacketImpl::prependInterpreter();
