JavaBeanBooleanPropertyBuilder for "Beans" without setters

I found this post for connecting a Java Bean as property binding with an existing JavaFX property. The binding should target a boolean property:

class MyClass {

    private boolean loaded;

    public boolean isLoaded() {

        return loaded;
    }

    // Value changed internally
}

For real beans, meaning beans with setters the following works like a charm. But I've the problem that there's no setter for the loaded property, just because it's set internally and shouldn't be modifyable for external classes.

BooleanProperty loadedProeprty = new JavaBeanBooleanPropertyBuilder()
    .bean(bean)
    .name("loaded")
    .getter("isLoaded")
    .build();

Is there any way to create still a property for such "beans" without a setter? For now I just get a NoSuchMethodException for the expected setter MyClass.setLoaded(boolean).

Solution

  • Use ReadOnlyJavaBeanBooleanPropertyBuilder instead.

    Normal properties in JavaFX are always read/write and thus require a setter. The read only variant creates a read only property and thus does not require a setter.
