Class ReactfxUtil

  • public final class ReactfxUtil
extends java.lang.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.

      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.

      Like rewireInit, with no initialisation.
      static <T> org.reactfx.Subscription rewireInit​(javafx.beans.property.Property<T> underlying, javafx.beans.property.Property<T> ui)
      Like the other overload, using the setter of the ui property.

      Binds the underlying property to a source of values (UI property).
      static <T> org.reactfx.Subscription subscribeDisposable​(javafx.beans.value.ObservableValue<? extends T> obs, java.util.function.Function<? super T,​org.reactfx.Subscription> subscriber)
      Subscribe to the values of the given observable, with a function that needs unsubscription when the value changes.
      static <T> org.reactfx.Subscription subscribeDisposable​(org.reactfx.EventStream<T> stream, java.util.function.Function<T,​org.reactfx.Subscription> subscriber)  
      static <T> org.reactfx.value.Val<T> vetoableNull​(org.reactfx.value.Val<T> base, java.time.Duration duration)  
      static org.reactfx.value.Val<java.lang.Boolean> vetoableYes​(org.reactfx.value.Val<java.lang.Boolean> base, java.time.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.

        Type Parameters:
        T - Type of values
        Parameters:
        underlying - The underlying property
        ui - The property exposed to the user (the one in this wizard)
        setter - Setter to initialise the UI value

        public static <T> org.reactfx.EventStream<T> reduceEntangledIfPossible​(org.reactfx.EventStream<T> input,
                                                                       java.util.function.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.
