Used to describe a small example of Property values

Bar.java

public class Bar {
    public String name;

    public Bar(String name) {
        this.name = name;
    }
}

Foo.java

public class Foo {
    private final ObjectProperty<Bar> bar;

    public Foo(Bar bar) {
        this.bar = new SimpleObjectProperty<>(this, "bar", bar);
    }

    public Bar getBar() {
        return bar.get();
    }

    public ObjectProperty<Bar> barProperty() {
        return bar;
    }

    public void setBar(Bar bar) {
        this.bar.set(bar);
    }
}

sample.json

[
    {
        "bar": {
            "@id": 1,     // ID property for the property value itself
            "value": {
                "@id": 2, // ID property added because it's required, not because it was specified, 
                          // though this should respect @JsonIdentityInfo
                "name": "bar" // Bar#name

    },
    {
        "bar": {

            "bound": 1,  // states it was bound, not actually holding a value

Test.java
