Inheritance diagram

The following diagram shows inheritance relationships for this type. Unresolved types are missing from the diagram.


Name Type Description
GatingPriorityQueue compound module

This module implements a priority queue with multiple inner queues each having its own periodic gate for packet selection and an optional shared memory buffer.


Name Type Default value Description
displayStringTextFormat string "contains %p pk (%l) pushed %u created %c\n pulled %o removed %r dropped %d"

determines the text that is written on top of the submodule

packetCapacity int -1

maximum number of packets in the queue, no limit by default

dataCapacity int -1b

maximum total length of packets in the queue, no limit by default

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

numQueues int
bitrate double
