question: private boolean stepValue ( ) { while ( true ) { if ( iter != null && iter . hasNext ( ) ) { svcs = ( ArrayList ) iter . next ( ) ; svcidx = svcs . size ( ) ; return true ; } if ( ! stepClass ( ) ) return false ; if ( iter == null ) return true ; } }
target:  Step to the next HashMap value, if any, reset svcs and svcidx, and return false if everything exhausted.
