tryRef()

bool RefCount::Counter::tryRef

(

)

Refs if not invalid. Note that you have to have guarantees that object is not dead. *.

unRef()

bool RefCount::Counter::unRef

(

)

Unref to zero will set it to an deleted state, and return true.

unRefDontInvalidate()

void RefCount::Counter::unRefDontInvalidate

(

)

Will allow it to go to zero.
