question: private boolean put ( boolean isRoot , Vector names , int len , Object value ) { if ( len == 0 ) { if ( isRoot ) { if ( rootValue != null ) return false ; rootValue = value ; } else { if ( otherValue != null ) return false ; otherValue = value ; } return true ; } else { Object name = names . elementAt ( len - 1 ) ; ContextMap nestedMap = ( ContextMap ) nameTable . get ( name ) ; if ( nestedMap == null ) { nestedMap = new ContextMap ( ) ; nameTable . put ( name , nestedMap ) ; } return nestedMap . put ( isRoot , names , len - 1 , value ) ; } }
target:  Adds a single path (isRoot, names) and a mode to be used for this path = context.
