/**
* A special interface marking implementations of {@link Document} that can be
* observed for changes. To observe a specific attribute, call the appropriate
* method for selecting that field.
*
* The following methods exist:
*
* - {@link #stringPropertyOf(String, Supplier)}
*
- {@link #integerPropertyOf(String, IntSupplier)}
*
- {@link #longPropertyOf(String, LongSupplier)}
*
- {@link #doublePropertyOf(String, DoubleSupplier)}
*
- {@link #floatPropertyOf(String, FloatSupplier)}
*
*
* To get an observable view of a specific child type, call
* {@link #observableListOf(String)}, or if you want all
* children as they have been exposed so far, call {@link #childrenProperty()}.
*
* As with all JavaFX components, the state of this property might not be
* updated immediately. It is therefore important to use the appropriate property
* getter methods to keep notified about changes to this document.
