question: public static boolean hasStepOfAssignableClass ( final Class superClass , final Traversal . Admin < ? , ? > traversal ) { for ( final Step < ? , ? > step : traversal . getSteps ( ) ) { if ( superClass . isAssignableFrom ( step . getClass ( ) ) ) { return true ; } } return false ; }
target:  Determine if the traversal has a step of an assignable class.
