ContentBasedClassifier

simple module

This module connects one packet producer to multiple packet consumers. It can be pushed with packets from the connected packet producer. When this happens, the classifier pushes the packet to one of its connected packet consumers based on the configured packet filters. The first matching expression determines the index of the output gate.

Extends

Name	Type	Description
PacketClassifierBase	simple module	This is a base module for various packet classifier modules. Derived modules must implement a single packet classifier function which determines the index of the output gate for the next pushed packet.

Parameters

Name	Type	Default value	Description
displayStringTextFormat	string	"classified %p pk (%l)"	determines the text that is written on top of the submodule
defaultGateIndex	int	0	default gate index if no matching labels are found
packetFilters	string		semicolon separated list of packet filter expressions (e.g. ping-;udp-), matches all packets by default
packetDataFilters	string		semicolon separated list of packet data filter expressions (e.g. inet::Ipv4Header and srcAddress = "10.0.0.1"), matches all packets by default
