void ns3::Icmpv4L4Protocol::NotifyNewAggregate ( void )

protectedvirtual

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 overriden 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.

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