class WeakPtrFlag
Defined at line 22 of file ../../src/lib/fxl/memory/weak_ptr_internal.h
|WeakPtr
<T
>|s have a reference to a |WeakPtrFlag| to determine whether they
are valid (non-null) or not. We do not store a |T*| in this object since
there may also be |WeakPtr
<U
>|s to the same object, where |U| is a superclass
of |T|.
This class in not thread-safe, though references may be released on any
thread (allowing weak pointers to be destroyed/reset/reassigned on any
thread).
