The uniform distribution RNG for NS-3.
This class supports the creation of objects that return random numbers from a fixed uniform distribution. It also supports the generation of single random numbers from various uniform distributions.
The low end of the range is always included and the high end of the range is always excluded.

double ns3::UniformVariable::GetValue | ( | void | ) | const |
Note: we have to re-implement this method here because the method is overloaded below for the two-argument variant and the c++ name resolution rules don't work well with overloads split between parent and child classes.
