Class SfcTableIndexMapper

java.lang.Object

org.opendaylight.sfc.genius.util.appcoexistence.SfcTableIndexMapper

public class SfcTableIndexMapper
extends Object

This class performs translation between a set of external SFC table indexes and the table indexes which are reserved by Genius for those tables. For doing so, the client module (sfc renderers using Genius) first builds the SfcTableIndexMapper (using the companion SfcTableIndexMapperBuilder class) by providing the table indexes it uses for each SFC table (this mechanism exists in order not to have a circular dependency between sfc-genius and the sfc renderer). Later, at flow writing time, the flow programmer will use this class in order to retrieve the correct table indexes for each SFC table

In short, this class allows to perform Genius-based application coexistence at table level, while keeping the previous application coexistence when genius is not used
