question: private boolean assertStaticType ( Class < ? > cls , Name n ) { int local = n . index ( ) ; Class < ? > aclass = localClasses [ local ] ; if ( aclass != null && ( aclass == cls || cls . isAssignableFrom ( aclass ) ) ) { return true ; } else if ( aclass == null || aclass . isAssignableFrom ( cls ) ) { localClasses [ local ] = cls ; } return false ; }
target:  Update localClasses type map.  Return true if the information is already present.
