Last

class Last(limit: Int) : Constraint

Last limit children: the values of data nodes sent by subscriptions will be limited to the last limit child nodes of the actual data nodes.

Child nodes are ordered with respect to their keys in a dedicated lexicographic order. For example, if the actual data node to send is {a:9, b:8, c:7}, the Last(2) constraint will send {b:8,c:7} to notification targets.
