    public abstract class AbstractJSObject
    extends Object
    implements JSObject
    Deprecated, for removal: This API element is subject to removal in a future version.
    Nashorn JavaScript script engine and APIs, and the jjs tool are deprecated with the intent to remove them in a future release.
    This is the base class for nashorn ScriptObjectMirror class. This class can also be subclassed by an arbitrary Java class. Nashorn will treat objects of such classes just like nashorn script objects. Usual nashorn operations like obj[i], obj.foo, obj.func(), delete obj.foo will be delegated to appropriate method call of this class.
    Since:
    1.8u40
