void ns3::UdpL4Protocol::DoDispose ( void )

protectedvirtual

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

Subclasses are expected to implement their real destruction code in an overriden 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.

Here is the call graph for this function:

void ns3::UdpL4Protocol::NotifyNewAggregate ( void )

protectedvirtual

This method is invoked whenever two sets of objects are aggregated together.

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

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.
