Detailed Description

holds a vector of std::pair of Ptr<Ipv4> and interface index.

Typically ns-3 Ipv4Interfaces are installed on devices using an Ipv4 address helper. The helper's Assign() method takes a NetDeviceContainer which holds some number of Ptr<NetDevice>. For each of the NetDevices in the NetDeviceContainer the helper will find the associated Ptr<Node> and Ptr<Ipv4>. It makes sure that an interface exists on the node for the device and then adds an Ipv4Address according to the address helper settings (incrementing the Ipv4Address somehow as it goes). The helper then converts the Ptr<Ipv4> and the interface index to a std::pair and adds them to a container – a container of this type.

The point is then to be able to implicitly associate an index into the original NetDeviceContainer (that identifies a particular net device) with an identical index into the Ipv4InterfaceContainer that has a std::pair with the Ptr<Ipv4> and interface index you need to play with the interface.

Here is the call graph for this function:

◆ Begin()

Ipv4InterfaceContainer::Iterator ns3::Ipv4InterfaceContainer::Begin ( ) const

Get an iterator which refers to the first pair in the container.

Pairs can be retrieved from the container in two ways. First, directly by an index into the container, and second, using an iterator. This method is used in the iterator method and is typically used in a for-loop to run through the pairs

Ipv4InterfaceContainer::Iterator i;
for (i = container.Begin (); i != container.End (); ++i)
  {
    std::pair<Ptr<Ipv4>, uint32_t> pair = *i;
    method (pair.first, pair.second);  // use the pair
  }

Returns: an iterator which refers to the first pair in the container.

Here is the caller graph for this function:

◆ End()

Ipv4InterfaceContainer::Iterator ns3::Ipv4InterfaceContainer::End ( ) const

Get an iterator which indicates past-the-last Node in the container.

Nodes can be retrieved from the container in two ways. First, directly by an index into the container, and second, using an iterator. This method is used in the iterator method and is typically used in a for-loop to run through the Nodes

NodeContainer::Iterator i;
for (i = container.Begin (); i != container.End (); ++i)
  {
    std::pair<Ptr<Ipv4>, uint32_t> pair = *i;
    method (pair.first, pair.second);  // use the pair
  }

Returns: an iterator which indicates an ending condition for a loop.

Here is the caller graph for this function:

◆ Get()

std::pair< Ptr< Ipv4 >, uint32_t > ns3::Ipv4InterfaceContainer::Get ( uint32_t i ) const

Get the std::pair of an Ptr<Ipv4> and interface stored at the location specified by the index.

Parameters

i	the index of the container entry to retrieve.

Returns: the std::pair of a Ptr<Ipv4> and an interface index

Note: The returned Ptr<Ipv4> cannot be used directly to fetch the Ipv4Interface using the returned index (the GetInterface () method is provided in class Ipv4L3Protocol, and not class Ipv4). An example usage is provided below.

Ipv4InterfaceContainer c;
...
std::pair<Ptr<Ipv4>, uint32_t> returnValue = c.Get (0);
Ptr<Ipv4> ipv4 = returnValue.first;
uint32_t index = returnValue.second;
Ptr<Ipv4Interface> iface =  DynamicCast<Ipv4L3Protocol> (ipv4)->GetInterface (index);

Parameters

i	index of ipInterfacePair in container
j	interface address index (if interface has multiple addresses)

Returns: the IPv4 address of the j'th address of the interface corresponding to index i.

If the second parameter is omitted, the zeroth indexed address of the interface is returned. Unless IP aliasing is being used on the interface, the second parameter may typically be omitted.
