Unassigned submodule parameters

Name	Type	Default value	Description
producer.displayStringTextFormat	string	"created %p pk (%l)"	determines the text that is written on top of the submodule
producer.packetNameFormat	string	"%a-%c"	see directives in module documentation
producer.packetRepresentation	string	"byteCount"	determines the chunk of the packet data
producer.packetLength	int
producer.packetData	int	-1
producer.attachCreationTimeTag	bool	true
producer.attachIdentityTag	bool	true
producer.attachDirectionTag	bool	true
producer.clockModule	string	""	relative path of a module that implements IClock(1,2); optional
producer.initialProductionOffset	double	0s
producer.productionInterval	double		elapsed time between subsequent packets pushed to the connected packet consumer
producer.scheduleForAbsoluteTime	bool	true	when a clock is used relative means that setting the clock will not affect the simulation time of the event
queue.displayStringTextFormat	string	"contains %p pk (%l) pushed %u\npulled %o removed %r dropped %d"	determines the text that is written on top of the submodule
queue.packetCapacity	int	100	maximum number of packets in the queue, no limit by default
queue.dataCapacity	int	-1b	maximum total length of packets in the queue, no limit by default
queue.dropperClass	string	"inet::queueing::PacketAtCollectionEndDropper"	determines which packets are dropped when the queue is overloaded, packets are not dropped by default; the parameter must be the name of a C++ class which implements the IPacketDropperFunction C++ interface and is registered via Register_Class
queue.comparatorClass	string	""	determines the order of packets in the queue, insertion order by default; the parameter must be the name of a C++ class which implements the IPacketComparatorFunction C++ interface and is registered via Register_Class
queue.bufferModule	string	""	relative module path to the IPacketBuffer module used by this queue, implicit buffer by default
collector.displayStringTextFormat	string	"received %p pk (%l)"	determines the text that is written on top of the submodule
collector.clockModule	string	""	relative path of a module that implements IClock(1,2); optional
collector.initialCollectionOffset	double	0s
collector.collectionInterval	double		elapsed time between subsequent packets pulled from the connected packet provider
collector.scheduleForAbsoluteTime	bool	true	when a clock is used relative means that setting the clock will not affect the simulation time of the event
