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
	Wrap functions, objects, and arguments into self contained 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.
	Configuration
	Configuration of simulation parameters and tracing.
	Debugging tools
	Assertions, breakpoints, logging, and abnormal program termination.
	Fatal Error Handlers
	Functions to help clean up when a fatal error is encountered.
	Hash Functions
	Generic Hash function interface.
	High Precision Q64.64
	Functions and class for high precision Q64.64 fixed point arithmetic.
	NonCopyable and Singleton
	Helpers to make classes non-copyable or singleton.
	Object
	Base classes which provide memory management and object aggregation.
	Random Variables
	ns-3 random numbers are provided via instances of ns3::RandomVariableStream.
	Scheduler and Events
	Manage the event list by creating and scheduling events.
	Simulator
	Control the virtual time and the execution of simulation events.
	Smart Pointer
	Heap memory management.
	System Services
	System-independent interfaces to operating system services: files system, threading, wall clock time.
	Testing
	Tools to define and execute unit tests.
	Tracing
	Publish/subscribe tools to collect and report changes to any values used by the various model components.
	Virtual Time
	Management of virtual time in real world units.
	Virtual Time Timer and Watchdog
	The Timer and Watchdog objects both facilitate scheduling functions to execute a specified virtual time in the future.

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: Debugging tools
• 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.

Macro Definition Documentation

#define NS_DEPRECATED

Mark a function as deprecated.

Users should expect deprecated features to be removed eventually.

When deprecating a feature, please update the documentation with information for users on how to update their code.

For example,

/*
 * Do something useful.
 *
 * \deprecated This method will go away in future versions of ns-3.
 * See instead TheNewWay()
 */
void SomethingUseful (void); 
/*
 * Do something more useful.
 */
void TheNewWay (void);
