DefaultGroupDescription

public DefaultGroupDescription(DeviceId deviceId,
                               GroupDescription.Type type,
                               GroupBuckets buckets,
                               GroupKey appCookie,
                               Integer groupId,
                               ApplicationId appId)

Constructor to be used by north bound applications. NOTE: The caller of this subsystem MUST ensure the appCookie provided in this API is immutable. NOTE: The caller may choose to pass in 'null' for the groupId. This is the typical case, where the caller allows the group subsystem to choose the groupId in a globally unique way. If the caller passes in the groupId, the caller MUST ensure that the id is globally unique (not just unique per device).

Parameters:

deviceId - device identifier

type - type of the group

buckets - immutable list of group bucket

appCookie - immutable application cookie of type DefaultGroupKey to be associated with the group

groupId - group identifier

appId - application id

DefaultGroupDescription

public DefaultGroupDescription(GroupDescription groupDesc)

Constructor to be used by group subsystem internal components. Creates group description object from another object of same type.

Parameters:

groupDesc - group description object

DefaultGroupDescription

public DefaultGroupDescription(DeviceId deviceId,
                               GroupDescription.Type type,
                               GroupBuckets buckets)

Constructor to be used by group subsystem internal components. Creates group description object from the information retrieved from data plane.

Parameters:

deviceId - device identifier

type - type of the group

buckets - immutable list of group bucket
