Detailed Description

Use BindingBuilder to create bindings.

You can use bindings to set the value of a property or property field with the value from another property, property field, or a data source.

To create a one-way binding:

            // Creates a one-way binding to the Opacity property of Node A.
            AbstractBinding binding =
                BindingBuilder.createOneWay("../Node A", Node2D.OpacityProperty);

To set a binding to the property of a node:

            // Sets the binding to Node B. Creates a binding runtime that you can use to remove the
            // binding.
            AbstractBindingRuntime runtime = nodeB.setBinding(binding, Node2D.OpacityProperty);

To remove a binding from a node:

            // Removes from Node B the binding to the Opacity property of Node A using the binding
            // runtime.
            nodeB.removeBinding(runtime);

To create a callback binding processor to a binding and to set a two-way binding between properties of two nodes:

            // Create a two-way binding to the Opacity property of Node A.
            AbstractBinding binding =
                BindingBuilder.createTwoWay("../Node A", Node2D.OpacityProperty);

            // Create a callback processor that accepts only float values greater than or equal to
            // 0.5.
            ObjectRef<CallbackBindingProcessor> processorRef =
                CallbackBindingProcessor.create(getDomain(), value -> {
                    if (value instanceof Float)
                    {
                        return ((float) value >= 0.5f);
                    }
                    return false;
                });

            // Add a callback processor to the binding. You must do this before adding the binding
            // to a node.
            binding.addProcessor(processorRef.get());

            // Bind from the Opacity property of Node A to the Opacity property of Node B.
            AbstractBindingRuntime runtime = nodeB.setBinding(binding, Node2D.OpacityProperty);

            final float opacityAa = 0.333333f;
            // Setting the opacity of Node A to less than 0.5 does not change the opacity of
            // Node B.
            nodeA.setOpacity(opacityAa);
            final float opacityBa = nodeB.getOpacity();

            final float opacityAb = 0.55555f;
            // Setting the opacity of Node A to a value greater than or equal to 0.5 changes the
            // opacity of Node B.
            nodeA.setOpacity(opacityAb);

To listen to changes in a property's value using a callback processor:

            // Create a one-way binding to an object's own Opacity property.
            AbstractBinding binding = BindingBuilder.createOneWay(".", Node2D.OpacityProperty);

            // Implement the action to be performed on change in the property as a callback
            // processor.
            ObjectRef<CallbackBindingProcessor> processorRef =
                CallbackBindingProcessor.create(getDomain(), value -> {
                    Log.debug("Opacity value changed to: " + value);

                    // The return does not matter here.
                    return true;
                });

            // Add a callback processor to the binding. You must do this before adding the binding
            // to a node.
            binding.addProcessor(processorRef.get());

            // Add binding to the node you want to observe.
            // Note the lack of target property and field.
            node.setBinding(binding);

To create, set, and remove bindings with an owner:

            // Create two bindings.
            AbstractBinding binding1 =
                BindingBuilder.createOneWay("../Node A", Node2D.OpacityProperty);
            AbstractBinding binding2 =
                BindingBuilder.createOneWay("../Node A", Node2D.BackgroundBrushProperty);
            // Bind to opacity and background brush properties, use Node A as owner.
            AbstractBindingRuntime runtime1 =
                nodeB.setBindingWithOwner(binding1, nodeA, Node2D.OpacityProperty);
            AbstractBindingRuntime runtime2 =
                nodeB.setBindingWithOwner(binding2, nodeA, Node2D.BackgroundBrushProperty);
            // Remove bindings at the same time using Node A as owner.
            nodeB.removeBindingsWithOwner(nodeA);

To create and set a modifier binding:

            // Create a binding to Render Transformation property Translation X property field of
            // Node A.
            AbstractBinding binding = BindingBuilder.createOneWay("../Node A",
                Node2D.RenderTransformationProperty, PropertyField.PropertyFieldTranslationX);
            // Bind it to Translation Y property field of the same node.
            AbstractBindingRuntime runtime = nodeA.setModifierBinding(binding,
                Node2D.RenderTransformationProperty, PropertyField.PropertyFieldTranslationY);
