Example 1 with PortNextObjectiveStoreKey

use of org.onosproject.segmentrouting.storekey.PortNextObjectiveStoreKey in project trellis-control by opennetworkinglab.

the class DefaultGroupHandler method getPortNextObjectiveId.

/**
 * Returns the next objective of type simple associated with the port on the
 * device, given the treatment. Different treatments to the same port result
 * in different next objectives. If no such objective exists, this method
 * creates one (if requested) and returns the id. Optionally metadata can be passed in for
 * the creation of the objective. Typically this is used for L2 and L3 forwarding
 * to compute nodes and containers/VMs on the compute nodes directly attached
 * to the switch.
 *
 * @param portNum the port number for the simple next objective
 * @param treatment the actions to apply on the packets (should include outport)
 * @param meta optional metadata passed into the creation of the next objective
 * @param createIfMissing true if a next object should be created if not found
 * @return int if found or created, -1 if there are errors during the
 *          creation of the next objective.
