JProperty

Java utility library that provides observable values, bindings with lazy evaluation and more. like JavaFX but simplified

Using JProperty with maven

</dependency>

Examples

Wrapping java primitives and objects.

final IntProperty intProperty = new SimpleIntProperty(8);
final FloatProperty floatProperty = new SimpleFloatProperty(1.7f);
final ObjectProperty<Object> objectProperty = new SimpleObjectProperty<>(new Object());

final ReadOnlyIntProperty readOnlyIntProperty = new SimpleIntProperty();
final ReadOnlyFloatProperty readOnlyFloatProperty = new SimpleFloatProperty();

Listening to value changes

intProperty.addListener(e -> {
    System.out.println("Changed" +
            " from " + e.getOldValue() +
            " to " + intProperty.get());
});
intProperty.set(5); // Prints output
intProperty.set(5); // Does not print output
intProperty.set(1); // Prints output

Building up expressions

final IntProperty aProperty = new SimpleIntProperty(8);
final IntProperty bProperty = new SimpleIntProperty(3);

final IntBinding expression = Bindings.add(aProperty, bProperty);

System.out.println(a.get()) // Prints 11
