How to convert ObjectProperty to StringProperty in JavaFX?

Question

There is a method to convert ObjectProperty<Integer> into IntegerProperty. Here it is:

https://docs.oracle.com/javase/8/javafx/api/javafx/beans/property/IntegerProperty.html#integerProperty-javafx.beans.property.Property-

Why there is no analogous method to convert ObjectProperty<String> to StringProperty? How to convert then?

Answer 1

Looking at the source for integerProperty, all it does is a bidirectional binding (and unbinding in finalize).

You could copy what integerProperty does, and modify it to use StringProperty:

public static StringProperty makeStringProperty(final Property<String> property) {
    Objects.requireNonNull(property, "Property cannot be null");

    return new StringPropertyBase() {
        {
            bindBidirectional(property);
        }

        @Override
        public Object getBean() {
            return null; // Virtual property, no bean
        }

        @Override
        public String getName() {
            return property.getName();
        }

        @Override
        protected void finalize() throws Throwable {
            try {
                unbindBidirectional(property);
            } finally {
                super.finalize();
            }
        }
    };
}

I've modified it a bit here so it does not use internal packages.
