class RefCounted

template <typename T, bool EnableAdoptionValidator = ZX_DEBUG_ASSERT_IMPLEMENTED>

class RefCounted

Defined at line 35 of file ../../zircon/system/ulib/fbl/include/fbl/ref_counted.h

Base class for a reference counted type. Use as

class Handle : public RefCounted

<Handle

> {

};

This supports intrusive atomic reference counting with adoption. This means

that a new object starts life at a reference count of 1 and has to be adopted

by a type (such as a fbl::RefPtr) that begins manipulation of the reference

count. If the reference count ever reaches zero, the object's lifetime is

over and it should be destroyed (Release() returns true if this is the case).

You might be wondering about the unused |T| template parameter. It exists so

that the base class of the derived object is a unique type. Without being a

template then you can have many unrelated classes which can be implicitly

upcasted to RefCounted* which is an undesirable situation for a mixin class

like this one. Specially because the destructor is not virtual. The same is

not possible via internal::RefCountedBase since the ctor and dtor are

protected.
