pt.unl.fct.di.novasys.babel.crdts.utils.ValueTsPair<V>

public class ValueTsPair<V>
extends Object

An helper class that stores a value and a timestamp. The value is represented as a generic type (e.g., a SerializabeType or a GenericCRDT) and the timestamp as Timestamp object. The class can be of great help in CRDTs that need to associate a value to a timestamp to perform conflict resolution.
