Annotation Type Experimental

@Retention(value=RUNTIME)
@Target(value={TYPE,FIELD,METHOD,PARAMETER,CONSTRUCTOR,LOCAL_VARIABLE,PACKAGE})
public @interface Experimental

An experimental user-facing API. Experimental API's might change or be removed in minor versions of Spark, or be adopted as first-class Spark API's. NOTE: If there exists a Scaladoc comment that immediately precedes this annotation, the first line of the comment must be ":: Experimental ::" with no trailing blank line. This is because of the known issue that Scaladoc displays only either the annotation or the comment, whichever comes first.
