StreamFilter

simple module

This module implements a packet filter using solely the stream name. The stream name must match the filter criteria in order the packet to pass through the filter.

Inheritance diagram

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

Extends

Name	Type	Description
PacketFilterBase	simple module	This is a base module for various packet filter modules. Derived modules must implement a single packet matcher function which determines if a packet is to be passed through or filtered out.

Parameters

Name	Type	Default value	Description
displayStringTextFormat	string	"dropped %d/%p pk (%k/%l)"	determines the text that is written on top of the submodule
backpressure	bool	false
mode	string	"both"
streamNameFilter	string	"*"	filter expression for the stream name

Properties

Name	Value	Description
display	i=block/downarrow
class	StreamFilter

Gates

Name	Direction	Size	Description
in	input
out	output

Signals

Name	Type	Unit
packetPushedIn	inet::Packet
packetPulledIn	inet::Packet
packetDropped	inet::Packet
packetPushedOut	inet::Packet
packetPulledOut	inet::Packet
