Annotation Type JsNullable

@Retention(value=RUNTIME)
 @Target(value=TYPE_USE)
 @Documented
public @interface JsNullable

JsNullable marks a type variable as nullable indicating that program elements of such a type can hold a null value.

Note that JsNullable can only be used on type variables in the context of a JsConstructor, a JsMethod, a JsProperty or a JsFunction method.

This annotation is informational in the GWT compiler but other compilers or tools might use it for example to annotate types in the output JavaScript program.
