ReevTicket

rescala.core.ReevTicket
final class ReevTicket[S[_], V](tx: of[S], var _before: V, accessHandler: AccessHandler[S]) extends DynamicTicket[S] with Result[V]

ReevTicket is given to the Derived reevaluate method and allows to access other reactives. The ticket tracks return values, such as dependencies, the value, and if the value should be propagated. Such usages make it unsuitable as an API for the user, where StaticTicket or DynamicTicket should be used instead.
