Help "OnOffHelper"

[Jaeyounj]

Hello,

I am testing a ns-3 example "wifi-adhoc.cc" but I can't find where the
definition of OnOffHelper is in Doxygen.

OnOffHelper onoff ("ns3::PacketSocketFactory", Address
(socketAddress));
onoff.SetAttribute ("OnTime", RandomVariableValue(ConstantVariable
(250)));
onoff.SetAttribute ("OffTime", RandomVariableValue(ConstantVariable
(0)));
onoff.SetAttribute ("DataRate", DataRateValue(DataRate(60000000)));
onoff.SetAttribute ("PacketSize", UintegerValue(2000));

Could anybody explain RandomVariableValue(...) in "OnTime" and
"OffTime"?

Even though I change the value in "OnTime", it works. Is it normal?
ex) onoff.SetAttribute ("OnTime", RandomVariableValue(ConstantVariable
(0)));

Thank you,
Jaeyoung

I think you found two bugs. I do not know why Doxygen is not picking up
the doxygen comments in src/helper/on-off-helper.h

We'll try to fix this as soon as possible.
