TAO_Intrusive_Ref_Count_Base< ACE_LOCK > Class Template Reference

Template base class to provide intrusive reference-counting to subclasses. This makes the subclass capable of using a TAO_Intrusive_Ref_Count_Handle<X> class as a smart-pointer to an X object. In this case, X is a sub-class of this class, TAO_Intrusive_Ref_Count_Base<ACE_LOCK>. The ACE_LOCK type is used to protect the atomic reference count data member. More...

class TAO_Intrusive_Ref_Count_Base< ACE_LOCK >

Template base class to provide intrusive reference-counting to subclasses. This makes the subclass capable of using a TAO_Intrusive_Ref_Count_Handle<X> class as a smart-pointer to an X object. In this case, X is a sub-class of this class, TAO_Intrusive_Ref_Count_Base<ACE_LOCK>. The ACE_LOCK type is used to protect the atomic reference count data member.
