GlobalValue objects provide a mechanism for default values not associated with particular object instantiations. This is useful, for example, when working with global functions.

Specific Types

Doubles

To declare a double valued global parameter, do something like the following:

#include "ns3/global-value.h"
#include "ns3/double.h"

GlobalValue g_sampleInterval("SampleInterval",
		             "How frequently samples are made.",
			     Double(2.0),
			     MakeDoubleChecker<double>(0.0));

To fetch the value, do something like:

  Simulator::Schedule(Seconds(((Double)(g_sampleInterval
					.GetValue())).Get()),
		      Example::Sample);
