 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.
 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 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.
 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.
 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.
 Tools to define and execute unit tests.
 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.

Macro Definition Documentation


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);

#define NS_UNUSED_GLOBAL (   x)    x

Mark a variable at file scope as unused.
