Detailed Description

template<typename T, typename PARENT = empty, typename DELETER = DefaultDeleter<T>>
class ns3::SimpleRefCount< T, PARENT, DELETER >

A template-based reference counting class.

This template can be used to give reference-counting powers to a class. This template does not require this class to have a virtual destructor or no parent class.

Note: if you are moving to this template from the RefCountBase class, you need to be careful to mark appropriately your destructor virtual if needed. i.e., if your class has subclasses, _do_ mark your destructor virtual.

This template takes 3 arguments but only the first argument is mandatory:

• T: the typename of the subclass which derives from this template class. Yes, this is weird but it's a common C++ template pattern whose name is CRTP (Curriously Recursive Template Pattern)
• PARENT: the typename of the parent of this template. By default, this typename is 'ns3empty' which is an empty class: compilers which implement the RBCO optimization (empty base class optimization) will make this a no-op
• DELETER: the typename of a class which implements a public static method named 'Delete'. This method will be called whenever the SimpleRefCount template detects that no references to the object it manages exist anymore.

Interesting users of this class include ns3::Object as well as ns3::Packet.

Member Function Documentation

template<typename T, typename PARENT = empty, typename DELETER = DefaultDeleter<T>>

uint32_t ns3::SimpleRefCount< T, PARENT, DELETER >::GetReferenceCount

(

void

)

const [inline]

Get the reference count of the object. Normally not needed; for language bindings.

template<typename T, typename PARENT = empty, typename DELETER = DefaultDeleter<T>>

void ns3::SimpleRefCount< T, PARENT, DELETER >::Ref

(

void

)

const [inline]

Increment the reference count. This method should not be called by user code. SimpleRefCount instances are expected to be used in conjunction with the Ptr template which would make calling Ref unecessary and dangerous.

template<typename T, typename PARENT = empty, typename DELETER = DefaultDeleter<T>>

void ns3::SimpleRefCount< T, PARENT, DELETER >::Unref

(

void

)

const [inline]

Decrement the reference count. This method should not be called by user code. SimpleRefCount instances are expected to be used in conjunction with the Ptr template which would make calling Ref unecessary and dangerous.
