  - ### get

    public Object get()
    Description copied from interface: `Binding`
    Reads the current value of the property (or other resource). When reading properties of objects that are primitive types, this will return an instance of the wrapper type. In some cases, a binding is read only and this method will throw a runtime exception.

  - ### isInvariant

    public boolean isInvariant()
    Returns false. Expansions reference properties that may change arbitrarily.
