void ns3::FlowProbe::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.

Reimplemented from ns3::Object.

Reimplemented in ns3::Ipv4FlowProbe.

Definition at line 39 of file flow-probe.cc.

Here is the caller graph for this function:

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

References m_stats.

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

Defined and not implemented to avoid misuse.

Returns

void ns3::FlowProbe::SerializeToXmlStream	(	std::ostream &	os,
		int	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
