Annotation Type Optional

@Documented
 @Target(value=METHOD)
 @Retention(value=SOURCE)
public @interface Optional

Denotes an optional member from the TypeScript model for the API. Annotated methods have a default implementation that throws UnsupportedOperationException when invoked. In a similar way that they have to in TypeScript, implementors need to actively opt into supporting the functionality by providing a custom implementation for the member.
