question: private Map processEvent ( MatchResult result ) { Map map = new HashMap ( ) ; for ( int i = 1 ; i < result . groupCount ( ) + 1 ; i ++ ) { Object key = matchingKeywords . get ( i - 1 ) ; Object value = result . group ( i ) ; map . put ( key , value ) ; } return map ; }
target:  Convert the match into a map. <p> Relies on the fact that the matchingKeywords list is in the same order as the groups in the regular expression
