        Returns an array of observable maps where each map observes the corresponding value property on all elements in the given domain set, for each property in the given array.
        Parameters:
        domainSet - the set of elements whose properties will be observed
        properties - array of value properties to observe on each element in the domain map's values collection
        Returns:
        an array of observable maps where each map observes the corresponding value property of the given domain set

      • observeEach

        @SafeVarargs
public static <K,​V,​P> IObservableMap<K,​? extends P>[] observeEach​(IObservableMap<K,​V> domainMap,
                                                                                    IValueProperty<? super V,​? extends P>... properties)
        Returns an array of observable maps where each maps observes the corresponding value property on all elements in the given domain map's values collection, for each property in the given array.
        Parameters:
        domainMap - the map of elements whose properties will be observed
        properties - array of value properties to observe on each element in the domain map's values collection
        Returns:
        a list of observable maps where each maps observes the corresponding value property on all elements in the given domain map's values collection, for each property in the given array

      • selfValue

        public static <T> IValueProperty<T,​T> selfValue​(java.lang.Object valueType)
        Returns a value property which takes the source object itself as the property value. This property may be used to wrap an object in an unmodifiable IObservableValue.
        Parameters:
        valueType - the value type of the property
        Returns:
        a value property which takes the source object itself as the property value.

      • selfList

        public static <E> IListProperty<java.util.List<E>,​E> selfList​(java.lang.Object elementType)
        Returns a list property which takes the source object (a List) as the property list. This property may be used to wrap an arbitrary List instance in an IObservableList.
        Parameters:
        elementType - the element type of the property
        Returns:
        a list property which takes the source object (a List) as the property list.

      • selfSet

        public static <E> ISetProperty<java.util.Set<E>,​E> selfSet​(java.lang.Object elementType)
        Returns a set property which takes the source object (a Set) as the property set. This property may be used to wrap an arbitrary Set instance in an IObservableSet.
        Parameters:
        elementType - the element type of the property
        Returns:
        a set property which takes the source object (a Set) as the property set.

      • selfMap

        public static <K,​V> IMapProperty<java.util.Map<K,​V>,​K,​V> selfMap​(java.lang.Object keyType,
                                                                                         java.lang.Object valueType)
        Returns a map property which takes the source object (a Map) as the property map. This property may be used to wrap an arbitrary Map instance in an IObservableMap.
        Parameters:
        keyType - the key type of the property
        valueType - the value type of the property
        Returns:
        a map property which takes the source object (a Map as the property map.

      • convertedValue

        public static <S,​T> IValueProperty<S,​T> convertedValue​(java.lang.Object valueType,
                                                                   java.util.function.Function<? super S,​? extends T> converter)
        Returns an IValueProperty whose value results from applying the given conversion function on the source object of the value property. Setting a value on the property is not supported.
        Parameters:
        valueType - value type of the property (after conversion); null if untyped
        converter - converter to apply to the source object of the value property; not null
        Returns:
        new instance of a value property, whose value is the result of applying the given converter to the source object
