Macro Definition Documentation

◆ Enter_Method

#define Enter_Method ( ... )

Denotes module class member function as callable from other modules.

Usage: Enter_Method(fmt, arg1, arg2...);

Example: Enter_Method("requestPacket(%d)",n);

The macro should be put at the top of every module member function that may be called from other modules. This macro arranges to temporarily switch the context to the called module (the old context will be restored automatically when the method returns), and also lets the graphical user interface animate the method call.

The argument(s) should specify the method name (and parameters) – it will be used for the animation. The argument list works as in printf(), so it is easy to include the actual parameter values.

See also: Enter_Method_Silent() macro

◆ Enter_Method_Silent

#define Enter_Method_Silent ( ... )

Denotes module class member function as callable from other modules.

This macro is similar to the Enter_Method() macro, only it does not animate the call on the GUI; the call is still recorded into the the event log file.

The macro may be called with or without arguments. When called with arguments, they should be a printf-style format string, and parameters to be substituted into it; the resulting string should contain the method name and the actual arguments.

Usage: Enter_Method_Silent();, Enter_Method_Silent(fmt, arg1, arg2...);

Example: Enter_Method_Silent("getRouteFor(address=%d)",address);

See also: Enter_Method() macro

◆ NedFunctionExt

typedef cValue(* NedFunctionExt) (cExpression::Context *context, cValue argv[], int argc)

Enumeration Type Documentation

◆ SimulationLifecycleEventType

enum SimulationLifecycleEventType

Event type for cISimulationLifecycleListener's lifecycleEvent() method.

Enumerator
LF_ON_STARTUP	Fired on the startup of the simulation program, after global configuration has been applied, but before any simulation has been set up.
LF_PRE_NETWORK_SETUP	Fired before network setup. At the time of the call, cSimulation's network type pointer (see getNetworkType()) already points to the type of the network that will be set up.
LF_POST_NETWORK_SETUP	Fired immediately after a network has been set up, and before callInitialize() has been invoked. If there has been an error during network setup, then only LF_SIMULATION_ERROR will be fired but not this event. For practical purposes, this event is almost the same as LF_PRE_NETWORK_INITIALIZE.
LF_PRE_NETWORK_INITIALIZE	Fired just before the network is initialized, i.e. before callInitialize() has been invoked on the system module.
LF_POST_NETWORK_INITIALIZE	Fired just after the network was initialized, i.e. after callInitialize() was invoked on the system module. If there is has been an error during initialization, then only LF_SIMULATION_ERROR will be fired but not this event.
LF_ON_SIMULATION_START	Fired immediately before the first event is processed by the simulation. This is similar to, but not the same as LF_POST_NETWORK_INITIALIZE, because on the GUI there might be a delay between the user setting up the network and actually hitting the Run button.
LF_ON_SIMULATION_PAUSE	Fired when simulation execution has been temporarily stopped by the user between two events.
LF_ON_SIMULATION_RESUME	Fired when the user resumes simulation execution after it has been paused. This event may be used e.g. by the real-time scheduler to resynchronize with wall clock time.
LF_ON_SIMULATION_SUCCESS	Fired just after processing the last event of the simulation (i.e. still before finalization). If the simulation stops with an error, LF_ON_SIMULATION_ERROR will be fired instead of this event.
LF_ON_SIMULATION_ERROR	Fired on a runtime error, in any stage of a simulation run's lifecycle (during network setup, initialization, in an event during simulation, during finalization and network deletion.)
LF_PRE_NETWORK_FINISH	Fired just before the network is finalized, i.e. before callFinish() has been invoked on the system module. This only happens if the simulation has completed successfully (did not stop with an error).
LF_POST_NETWORK_FINISH	Fired immediately after the network has been finalized, i.e. after callFinish() invocation has taken place on the system module. If there has been an error during finalization, then only LF_ON_SIMULATION_ERROR will be fired but not this event.
LF_ON_RUN_END	Fired after the simulation has been terminated, either by calling finish() or because of an error any previous state (including network setup). This event is distinct from LF_PRE_NETWORK_DELETE, because when using a GUI, there might be a delay between the simulation terminating and the user action that causes the network to be deleted. Note that using the GUI, it is also possible for the user to skip finalization of the network (even if there was no error), so LF_PRE_NETWORK_FINISH / LF_POST_NETWORK_FINISH are not guaranteed to have been fired prior to this event.
LF_PRE_NETWORK_DELETE	Fired before the network is deleted, i.e. before cSimulation's deleteNetwork() has been called. This event is fired even if there was an error during network setup.
LF_POST_NETWORK_DELETE	Fired after the network has been deleted, i.e. cSimulation's deleteNetwork() was called. At the time of the call, the network type pointer in cSimulation (see getNetworkType()) is still valid. This event is not fired if an error occurs during deleteNetwork().
LF_ON_SHUTDOWN	Fired before the simulation program exits. At the time of the call, the simulated network has been torn down, but the simulation infrastructure (scheduler object, etc) is still in place.
