Class ReactfxUtil

  • public final class ReactfxUtil
extends Object
    Extensions to ReactFX Val and EventStreams. Some can be deemed as too general for this project: I'd like them to be moved to the reactfx main project -> but it's unmaintained.

      • vetoableYes

        public static org.reactfx.value.Val<Boolean> vetoableYes​(org.reactfx.value.Val<Boolean> base,
                                                         Duration vetoPeriod)
        Returns a val that reflects "true" values of the input val only after the [vetoPeriod], and only if they're not vetoed by a "false" value emitted during the veto period. "false" values are reflected immediately.

      • vetoableNull

        public static <T> org.reactfx.value.Val<T> vetoableNull​(org.reactfx.value.Val<T> base,
                                                        Duration duration)

      • reduceEntangledIfPossible

        public static <T> org.reactfx.EventStream<T> reduceEntangledIfPossible​(org.reactfx.EventStream<T> input,
                                                                       BiPredicate<T,​T> canReduce,

        Like reduce if possible, but can be used if the events to reduce are emitted in extremely close succession, so close that some unrelated events may be mixed up. This reduces each new event with a related event in the pending notification chain instead of just considering the last one as a possible reduction target.
