◆ DoDispose()

void ns3::FlowMonitor::DoDispose ( )

overrideprotectedvirtual

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.

References m_flowProbes.

◆ GetFlowStats()

const FlowMonitor::FlowStatsContainer & ns3::FlowMonitor::GetFlowStats ( ) const

Retrieve all collected the flow statistics.

Note, if the FlowMonitor has not stopped monitoring yet, you should call CheckForLostPackets() to make sure all possibly lost packets are accounted for.

Returns: the flows statistics

◆ GetInstanceTypeId()

TypeId ns3::FlowMonitor::GetInstanceTypeId ( ) const

Get the most derived TypeId for this Object.

This method is typically implemented by ns3::Object::GetInstanceTypeId but some classes which derive from ns3::ObjectBase directly have to implement it themselves.

Returns: The TypeId associated to the most-derived type of this instance.

Implements ns3::ObjectBase.
