Detailed Description

template<typename T>
class ns3::Ptr< T >

smart pointer class similar to boost::intrusive_ptr

This smart-pointer class assumes that the underlying type provides a pair of Ref and Unref methods which are expected to increment and decrement the internal refcount of the object instance.

This implementation allows you to manipulate the smart pointer as if it was a normal pointer: you can compare it with zero, compare it against other pointers, assign zero to it, etc.

It is possible to extract the raw pointer from this smart pointer with the GetPointer and PeekPointer methods.

If you want to store a newed object into a smart pointer, we recommend you to use the Create template functions to create the object and store it in a smart pointer to avoid memory leaks. These functions are really small convenience functions and their goal is just is save you a small bit of typing.


Constructor & Destructor Documentation

template<typename T >
ns3::Ptr< T >::Ptr (  ) 

Create an empty smart pointer

template<typename T>
ns3::Ptr< T >::Ptr ( T *  ptr  ) 
Parameters:
ptr raw pointer to manage

Create a smart pointer which points to the object pointed to by the input raw pointer ptr. This method creates its own reference to the pointed object. The caller is responsible for Unref()'ing its own reference, and the smart pointer will eventually do the same, so that object is deleted if no more references to it remain.

template<typename T>
ns3::Ptr< T >::Ptr ( T *  ptr,
bool  ref 
)
Parameters:
ptr raw pointer to manage
ref if set to true, this method calls Ref, otherwise, it does not call Ref.

Create a smart pointer which points to the object pointed to by the input raw pointer ptr.


Friends And Related Function Documentation

template<typename T >
T * GetPointer ( const Ptr< T > &  p  )  [related]
Parameters:
p smart pointer
Returns:
the pointer managed by this smart pointer.

The underlying refcount is incremented prior to returning to the caller so the caller is responsible for calling Unref himself.

template<typename T >
T * PeekPointer ( const Ptr< T > &  p  )  [related]
Parameters:
p smart pointer
Returns:
the pointer managed by this smart pointer.

The underlying refcount is not incremented prior to returning to the caller so the caller is not responsible for calling Unref himself.
