◆ AddPacketDropStats()

void ns3::FlowProbe::AddPacketDropStats	(	FlowId	flowId,
		uint32_t	packetSize,
		uint32_t	reasonCode

◆ DoDispose()

void ns3::FlowProbe::DoDispose ( void )

protectedvirtual

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.

Reimplemented in ns3::Ipv6FlowProbe, and ns3::Ipv4FlowProbe.

Definition at line 50 of file flow-probe.cc.

References ns3::Object::DoDispose(), and m_flowMonitor.

Referenced by ns3::Ipv4FlowProbe::DoDispose(), and ns3::Ipv6FlowProbe::DoDispose().

◆ GetStats()

FlowProbe::Stats ns3::FlowProbe::GetStats ( ) const

Get the partial flow statistics stored in this probe.

With this information you can, for example, find out what is the delay from the first probe to this one.

Returns: the partial flow statistics

Definition at line 80 of file flow-probe.cc.

References m_stats.

◆ GetTypeId()

TypeId ns3::FlowProbe::GetTypeId ( void )

static

Register this type.

Returns: The TypeId.

References ns3::TypeId::SetParent().

◆ operator=()

FlowProbe& ns3::FlowProbe::operator= ( FlowProbe const & )

private

Defined and not implemented to avoid misuse.

Returns

◆ SerializeToXmlStream()

void ns3::FlowProbe::SerializeToXmlStream	(	std::ostream &	os,
		uint16_t	indent,
		uint32_t	index
	)		const

Serializes the results to an std::ostream in XML format.

Parameters

os	the output stream
indent	number of spaces to use as base indentation level
index	FlowProbe index

Definition at line 86 of file flow-probe.cc.
