void RefBase ()

When constructing these objects, prefer using sp::make

>. Using a RefBase

object on the stack or with other refcount mechanisms (e.g.

std::shared_ptr) is inherently wrong. RefBase types have an implicit

ownership model and cannot be safely used with other ownership models.

void ~RefBase ()

void extendObjectLifetime (int32_t mode)

void onFirstRef ()

Invoked after creation of initial strong pointer/reference.

void onLastStrongRef (const void * id)

Invoked when either the last strong reference goes away, or we need to undo

the effect of an unnecessary onIncStrongAttempted.

bool onIncStrongAttempted (uint32_t flags, const void * id)

Only called in OBJECT_LIFETIME_WEAK case. Returns true if OK to promote to

strong reference. May have side effects if it returns true.

The first flags argument is always FIRST_INC_STRONG.

TODO: Remove initial flag argument.

void onLastWeakRef (const void * id)

Invoked in the OBJECT_LIFETIME_WEAK case when the last reference of either

kind goes away. Unused.

TODO: Remove.
