class Between : Constraint
Children between: the values of data nodes sent by subscriptions will be limited to the child nodes of the actual data nodes whose keys are between startKey and endKey (included).
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 Between("a", "abc") constraint will send {a:9} to
notification targets.
Between(startKey: String, endKey: String)
Children between: the values of data nodes sent by subscriptions will be limited to the child nodes of the actual data nodes whose keys are between startKey and endKey (included). |
val endKey: String
Key that is greater than or equal to (following the lexicographic order) the key of last child that can be sent by subscriptions. |
|
val startKey: String
Key that is lower than or equal to (following the lexicographic order) the key of first child that can be sent by subscriptions. |
