Direct Known Subclasses:

SimpleTrace, TCPTrace

public abstract class TraceInput

extends TrafficSourceComponent

TraceInput output packets to down@ port based on a trace file. To use the class, one must assigned to it a java.io.Reader which is associated with the opened trace file.

A subclass must override setNextPacket(drcl.net.FooPacket) to set the size of next packet and return its birth time based on the trace file. In addition, a subclass also needs to implement the looping operation. When the looping flag is enabled, the trace file is repeated every loopPeriod second. The associated traffic model is made up by the load, burst and MTU properties.

Method Detail

setNextPacket

protected abstract double setNextPacket(FooPacket nextpkt_)

Description copied from class: TrafficSourceComponent

Sets up next packet. Given the next packet, this method should set its packet size and return the birth time of the packet. The birth time is the time relative to the start time of this traffic source.

Overrides:

setNextPacket in class TrafficSourceComponent

reset

public void reset()

Description copied from class: Component

Resets the component for being used anew. All the internal variables must be set to the initial state. All the ports and child components are reset as well.

Overrides:

reset in class TrafficSourceComponent

duplicate

public void duplicate(java.lang.Object source_)

Description copied from class: Component

Duplicates the content of source_, including ID, name, child components and connections among them, to this component. Subclasses need to override this method to copy its own variables.

Overrides:

duplicate in class TrafficSourceComponent

info

public java.lang.String info()

Description copied from class: Component

Returns information regarding this component. Subclasses should override this method to provide useful information at run-time.

Overrides:

info in class TrafficComponent

load

public void load(java.lang.String filename_)

Loads the trace file into this component.

setReader

public void setReader(java.io.Reader r_)

getReader

public java.io.Reader getReader()

setTrafficModel

public void setTrafficModel(TrafficModel traffic_)

Description copied from class: TrafficComponent

Sets the associated traffic model.

Overrides:

setTrafficModel in class TrafficComponent

getTrafficModel

public TrafficModel getTrafficModel()

Description copied from class: TrafficComponent

Returns the associated traffic model.

Overrides:

getTrafficModel in class TrafficComponent

setLoad

public void setLoad(double load_)

getLoad

public double getLoad()

setBurst

public void setBurst(int b_)

getBurst

public int getBurst()

setMTU

public void setMTU(int mtu_)

getMTU

public int getMTU()

isLoopEnabled

public boolean isLoopEnabled()

Returns true if looping the trace is enabled.

setLoopEnabled

public void setLoopEnabled(boolean v_)

Enables/disables looping.

getLoopPeriod

public double getLoopPeriod()

Returns the looping period.

setLoopPeriod

public void setLoopPeriod(double p_)

Sets the looping period.
