Annotation Interface JsExpression

@Documented @Target(METHOD) @Retention(RUNTIME) public @interface JsExpression
The JavaScript that a method of a JavaScript definition runs, as a constant expression.

The annotated method is called through Element.executeJs(Class). Its arguments are the parameters of the expression, referenced positionally as $0, $1, …, and the element the definition was obtained from is this — the same contract as Element.executeJs(String, Object...), except that the expression is a constant of the interface instead of a string built at the call site.
