Constructor Detail

Filter

public Filter()

Method Detail

getTC

protected java.lang.String getTC()

Get a string representation which we can use in the toString() methods in the derived classes

Returns:

code for tcd

decrPrio

public void decrPrio()

give the filter lower priority

setPrio

public void setPrio(short prio)

Set the priority. Higher number means lower priority.

Parameters:

prio - priority

setProtocol

public void setProtocol(java.lang.String protocol)

Set the protocol.

Parameters:

protocol - protocol (e.g. "ip")

setMeter

public void setMeter(long rate,
                     long burst,
                     boolean cont)

Add a (token bucket) meter to the filter.

Parameters:

rate - token rate

burst - burst

cont - continue (and reclassify) or drop if bucket empty?

getMeter

protected java.lang.String getMeter()

Get a string representation (tc code) for the attached meter.

Returns:

tccode for meter

setEstimator

public void setEstimator(int interval,
                         int timer)

set the qdiscs estimator
