Unassigned submodule parameters¶

Name	Type	Default value	Description
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, supports displaying pars, watches, and module-specific information
queue.packetCapacity	int	-1	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	“”	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
streamer.displayStringTextFormat	string	“processed {numProcessedPackets} pk ({processedTotalLength})”	Determines the text that is written on top of the submodule, supports displaying pars, watches, and module-specific information
streamer.clockModule	string	“”	Relative path of a module that implements IClock(1,:ref:2 <neddoc-msg-inet-iclock>); optional
streamer.datarate	double	nan bps
outboundEmitter.displayStringTextFormat	string	“processed {numProcessedPackets} pk ({processedTotalLength})”	Determines the text that is written on top of the submodule, supports displaying pars, watches, and module-specific information
outboundEmitter.packetFilter	object	“*”	Which packets are considered, matches all packets by default
outboundEmitter.direction	string	“undefined”
outboundEmitter.signalName	string
fcsChecker.displayStringTextFormat	string	“dropped {numDroppedPackets}/{numProcessedPackets} pk ({droppedTotalLength}/{processedTotalLength})”	Determines the text that is written on top of the submodule, supports displaying pars, watches, and module-specific information
fcsChecker.backpressure	bool	false
fcsChecker.popFcs	bool	false
inboundEmitter.displayStringTextFormat	string	“processed {numProcessedPackets} pk ({processedTotalLength})”	Determines the text that is written on top of the submodule, supports displaying pars, watches, and module-specific information
inboundEmitter.packetFilter	object	“*”	Which packets are considered, matches all packets by default
inboundEmitter.direction	string	“undefined”
inboundEmitter.signalName	string
