Member Function Documentation

◆ DoDispose()

void ns3::Icmpv4L4Protocol::DoDispose ( void  )
privatevirtual

Destructor implementation.

This method is called by Dispose() or by the Object's destructor, whichever comes first.

Subclasses are expected to implement their real destruction code in an overridden version of this method and chain up to their parent's implementation once they are done. i.e, for simplicity, the destructor of every subclass should be empty and its content should be moved to the associated DoDispose() method.

It is safe to call GetObject() from within this method.

Reimplemented from ns3::Object.

Notify all Objects aggregated to this one of a new Object being aggregated.

This function must be implemented in the stack that needs to notify other stacks connected to the node of their presence in the node.

This method is invoked whenever two sets of Objects are aggregated together. It is invoked exactly once for each Object in both sets. This method can be overridden by subclasses who wish to be notified of aggregation events. These subclasses must chain up to their base class NotifyNewAggregate() method.

It is safe to call GetObject() and AggregateObject() from within this method.
