public class Classifier

extends Component

The component classifies the incoming packets and pass them on at corresponding ports. Specifically, this component uses the PktClassifier to obtain an integer key for an incoming packet and then retrieves the corresponding port from its key-port map.

The class defines a set of add() and remove() methods to configure the key-port map.

Method Detail

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 Component

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.

Specified by:

duplicate in interface ObjectDuplicable

Overrides:

duplicate in class Component

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 Component

setPktClassifier

public void setPktClassifier(PktClassifier pc_)

getPktClassifier

public PktClassifier getPktClassifier()
