Modules
	Attributes
	The ns-3 attribute system is the mechanism used in ns-3 to organize, document, and modify the values used by the various component models.
	Callbacks
	Command Line Parsing
	A uniform way to specify program documentation, allowed command line arguments and help strings, and set any attribute or global value, all from the command line directly.
	Debugging
	Hash Functions
	Object
	Random Variables
	ns-3 random numbers are provided via instances of ns3::RandomVariableStream.

Detailed Description

The "core" module contains:

• a time management class to hold a time and convert between various time units: ns3::Time
• a scheduler base class used to implement new simulation event schedulers: ns3::Scheduler and ns3::SchedulerFactory
• a simulator class used to create, schedule and cancel events: ns3::Simulator
• a Functor class: ns3::Callback
• an os-independent interface to get access to the elapsed wall clock time: ns3::SystemWallClockMs
• a class to register regression tests with the test manager: ns3::Test and ns3::TestManager
• debugging facilities: Logging, Assert
• Random Variables
• a base class for objects which need to support per-instance "attributes" and trace sources: ns3::ObjectBase
• a base class for objects which need to support reference counting and dynamic object aggregation: ns3::Object
• a smart-pointer class ns3::Ptr designed to work together with ns3::Object
• a configuration class used to set and control all attributes and trace sources in a simulation: ns3::Config.
