changes from ns3.14 to ns3.15 with RandomVariableValue

[amelie...@gmail.com]

the old code is
RandomVariableValue (ConstantVariable (0))
the new code is
StringValue("ns3::ConstantRandomVariable[Constant=0]")

but when i meet this code
RandomVariableValue (ConstantVariable (m_totalTime))
 i do not know how to change it.
 could you help me?
thanks a lot !

Have you tried:

StringValue("ns3::ConstantRandomVariable[Constant=m_totalTime]")

it did not work,"Invalid value for attribute set (OnTime) on ns3::OnOffApplication"

Ah, that was a bad suggestion on my part. This value takes a string so
there cannot be a variable name embedded in it. You must instead build
the string that you want at runtime and pass it in; e.g.

#include <sstream>

std::ostringstream stream;
stream << "ns3::ConstantRandomVariable[Constant=" << m_totalTime << "]";

and then later use it such as:

StringValue (stream.str())
