C++ definition

Identifies the stream of a packet using packet filter expressions. It can check for arbitrary packet data and assign an if a match was found then the stream is attached to the packet in the ~StreamReq tag.

Extends

Name	Type	Description
PacketFlowBase	simple module	Base module for various packet flow modules. A packet flow module passes or streams all pushed or pulled packets after processing them from its input to its output.

Parameters

Name	Type	Default value	Description
displayStringTextFormat	string	"processed %p pk (%l)"	Determines the text that is written on top of the submodule, supports displaying pars, watches, and module-specific information
hasSequenceNumbering	bool	true
mapping	object	[]	Array of objects, where each object specifies a stream name and a packetFilter, for example [{stream: "s0", packetFilter: "*"}, ...]
