Description copied from interface: VirtualNetworkFlowObjectiveStore

Adds a NextGroup to the store, by mapping it to the nextId as key, and replacing any previous mapping.

Specified by:

putNextGroup in interface VirtualNetworkFlowObjectiveStore

Parameters:

networkId - a virtual network identifier

nextId - an integer

group - a next group opaque object

getNextGroup

public org.onosproject.net.behaviour.NextGroup getNextGroup(NetworkId networkId,
                                                            java.lang.Integer nextId)

Description copied from interface: VirtualNetworkFlowObjectiveStore

Fetch a next group from the store.

Specified by:

getNextGroup in interface VirtualNetworkFlowObjectiveStore

Parameters:

networkId - a virtual network identifier

nextId - an integer used as key

Returns:

a next group, or null if group was not found

removeNextGroup

public org.onosproject.net.behaviour.NextGroup removeNextGroup(NetworkId networkId,
                                                               java.lang.Integer nextId)

Description copied from interface: VirtualNetworkFlowObjectiveStore

Remove a next group mapping from the store.

Specified by:

removeNextGroup in interface VirtualNetworkFlowObjectiveStore

Parameters:

networkId - a virtual network identifier

nextId - the key to remove from the store.

Returns:

the next group which mapped to the nextId and is now removed, or null if no group mapping existed in the store

getAllGroups

public java.util.Map<java.lang.Integer,org.onosproject.net.behaviour.NextGroup> getAllGroups(NetworkId networkId)

Description copied from interface: VirtualNetworkFlowObjectiveStore
