Macro Definition Documentation

◆ Register_ResultFilter

#define Register_ResultFilter	(	NAME,
		CLASSNAME
	)

Registers a result filter.

The class must be a subclass of cResultFilter. Registered result filters can be used in the source= and record= attributes of @statistic properties in NED files, and with the **.result-recording-modes= configuration option.

#define Register_ResultFilter2	(	NAME,
		CLASSNAME,
		DESCRIPTION
	)

Registers a result filter with a description string.

The class must be a subclass of cResultFilter. Registered result filters can be used in the source= and record= attributes of @statistic properties in NED files, and with the **.result-recording-modes= configuration option.

◆ Register_ResultRecorder

#define Register_ResultRecorder	(	NAME,
		CLASSNAME
	)

Registers a result recorder class.

The class must be a subclass of cResultRecorder.

Registered result recorders can be used in the record= attributes of @statistic properties in NED files, and with the **.result-recording-modes= configuration option.

◆ Register_ResultRecorder2

#define Register_ResultRecorder2	(	NAME,
		CLASSNAME,
		DESCRIPTION
	)

Registers a result recorder class with a description string.

The class must be a subclass of cResultRecorder.

Registered result recorders can be used in the record= attributes of @statistic properties in NED files, and with the **.result-recording-modes= configuration option.

◆ Define_NED_Math_Function

#define Define_NED_Math_Function	(	NAME,
		ARGCOUNT
	)

Registers a C/C++ mathematical function for use in NED and ini files. The function may take 0, 1, 2 or 3 double arguments, and must return a double. Corresponding C/C++ typedefs: MathFuncNoArg, MathFunc1Arg, MathFunc2Args, MathFunc3Args, MathFunc4Args.

Commonly used <math.h> functions have Define_NED_Math_Function() lines in the OMNeT++ simulation kernel.

See also: Define_NED_Function

◆ Define_NED_Math_Function2

#define Define_NED_Math_Function2	(	NAME,
		FUNCTION,
		ARGCOUNT
	)

Like Define_NED_Math_Function(), but takes three arguments, the second one being the pointer to the function. This macro allows registering a function with a different name from its implementation.

◆ Define_NED_Math_Function3

#define Define_NED_Math_Function3	(	NAME,
		ARGCOUNT,
		CATEGORY,
		DESCRIPTION
	)

Like Define_NED_Math_Function(), but takes category and description strings as well.

◆ Define_NED_Math_Function4

#define Define_NED_Math_Function4	(	NAME,
		FUNCTION,
		ARGCOUNT,
		CATEGORY,
		DESCRIPTION
	)

Like Define_NED_Math_Function2(), but takes category and description strings as well.

◆ Define_NED_Function

#define Define_NED_Function	(	FUNCTION,
		SIGNATURE
	)

Registers a C/C++ function for use in NED and ini files; see cNedFunction. FUNCTION is a pointer to the function, and SIGNATURE is the function's signature in NED.

The C++ function should have the following signature:

cNedValue f(cComponent *context, cNedValue argv[], int argc)

SIGNATURE is a string with the following syntax: returntype functionname(argtype1 argname1, ...), where a type can be one of 'bool', 'int', 'double', 'quantity' ('double' with measurement unit), 'string', 'xml' and 'any'. Optional arguments are denoted by appending a '?' to their names. To let the function accept any number of additional arguments of arbitrary types, add ',...' to the signature.

Example:

Define_NED_Function(uniformFunc,"quantity uniform(quantity a, quantity b, long rng?)")

◆ Define_NED_Function2

#define Define_NED_Function2	(	FUNCTION,
		SIGNATURE,
		CATEGORY,
		DESCRIPTION
	)

Like Define_NED_Function(), but allows one to specify a category string and documentation as well.

◆ Register_Class

#define Register_Class ( CLASSNAME )

Register class. This defines a factory object which makes it possible to create an object by the passing class name to the createOne() function. The class must be a subclass of cObject, otherwise a compile-time error will occur: "cannot convert..."

See also: cObjectFactory, cObjectFactory::createOne(), cObjectFactory::isInstance()

◆ Register_Abstract_Class

#define Register_Abstract_Class ( CLASSNAME )

Register an abstract class. Registration makes it possible to dynamically test whether an object is a subclass of the registered class (see cObjectFactory::isInstance()). The class must be a subclass of cObject, otherwise a compile-time error will occur: "cannot convert..."

See also: cObjectFactory, cObjectFactory::isInstance()

◆ Define_Module

#define Define_Module ( CLASSNAME )

Announces the C++ simple module class to OMNeT++, and couples it with the NED simple module declaration of the same name.

◆ Define_Channel

#define Define_Channel ( CLASSNAME )

Announces the C++ channel class to OMNeT++, and couples it with the NED channel declaration of the same name.

◆ Register_ClassDescriptor

#define Register_ClassDescriptor ( DESCRIPTORCLASS )

Internal. Registers a class descriptor which provides reflection information.

◆ Register_GlobalConfigOption

#define Register_GlobalConfigOption	(	ID,
		NAME,
		TYPE,
		DEFAULTVALUE,
		DESCRIPTION
	)

Registers a global configuration option.

◆ Register_PerRunConfigOption

#define Register_PerRunConfigOption	(	ID,
		NAME,
		TYPE,
		DEFAULTVALUE,
		DESCRIPTION
	)

Registers a per-run configuration option.

◆ Register_GlobalConfigOptionU

#define Register_GlobalConfigOptionU	(	ID,
		NAME,
		UNIT,
		DEFAULTVALUE,
		DESCRIPTION
	)

Registers a global configuration option with type==CFG_DOUBLE and an expected unit of measurement.

◆ Register_PerRunConfigOptionU

#define Register_PerRunConfigOptionU	(	ID,
		NAME,
		UNIT,
		DEFAULTVALUE,
		DESCRIPTION
	)

◆ Register_MessagePrinter

#define Register_MessagePrinter ( CLASSNAME )

Registers a message printer class (cMessagePrinter)

◆ Register_Enum

#define Register_Enum	(	NAME,
		VALUES
	)

Registers an enum.

Example:

enum State { IDLE, BUSY, SLEEPING };
Register_Enum(State, (
   State::IDLE,
   State::BUSY,
   State::SLEEPING));

See also: cEnum

◆ Register_Enum2

#define Register_Enum2	(	VAR,
		NAME,
		VALUES
	)

Registers an enum, and makes it accessible via a global cEnum* pointer, using explicit strings for the enum type and it member names.

Example:

enum State { IDLE, BUSY, SLEEPING };
Register_Enum2(stateEnum, "State", (
   "idle",     State::IDLE,
   "busy",     State::BUSY,
   "sleeping", State::SLEEPING,
   nullptr)); // see note below

Note: One may need to put (void*)nullptr as the last item, due to a bug in certain compilers (they push a 32-bit zero value instead a of a 64-bit one in the "..." arg list, causing the called function to be unable to determine the end of the argument list).

See also: cEnum

◆ Register_Figure

#define Register_Figure	(	NAME,
		CLASSNAME
	)

Registers a new figure type. The macro expects a type name string (an identifier that can be used in the type attribute of the @figure property), and a C++ class name. The class must be derived from cFigure.

Note: Register_Figure() includes registration the figure class via a Register_Class().

Example:

Register_Figure("polyline", cPolylineFigure);
