Annotation Type Private

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

A class that is considered private to the internals of Spark -- there is a high-likelihood they will be changed in future versions of Spark. This should be used only when the standard Scala / Java means of protecting classes are insufficient. In particular, Java has no equivalent of private[spark], so we use this annotation in its place. NOTE: If there exists a Scaladoc comment that immediately precedes this annotation, the first line of the comment must be ":: Private ::" 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.
