All Known Implementing Classes:: AbstractJSObject, ScriptObjectMirror

@Deprecated(since="11",
            forRemoval=true)
public interface 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 interface can be implemented 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 interface.

Since:: 1.8u40
