Apache Flink CEP pattern detection with java

Question

I want to do;
to start with CEP with any of the arraylist elements included in the map structure and to continue with the rest of the arraylist elements I have started.
map and pattern structure:

final Map< Integer,ArrayList<String>> deger = new HashMap<Integer,ArrayList<String>>();
        deger.put(1,new ArrayList<String>(Arrays.asList("h:1","l:1","g:0")));
        deger.put(2,new ArrayList<String>(Arrays.asList("h:1","l:1","g:1")));
        deger.put(3,new ArrayList<String>(Arrays.asList("h:2","l:3","g:1")));
        deger.put(4,new ArrayList<String>(Arrays.asList("h:0","l:2","g:2")));

 for(int i=1;i<deger.size()+1;i++) {
            temp1.add(deger.get(i));
        }

Pattern<String,?> pattern = Pattern.<String>begin("start").where(
                new SimpleCondition<String>() {
//                    @Override
                    public boolean filter(String value) throws Exception {

                        for (ArrayList<String> aa: temp1){
                            for (String dd : aa)
                                if(value.equals(dd)){ 
                                    return true;
                                }
                        }
                        return false;
                    }
                }
        ).followedBy("middle").where(
                new SimpleCondition<String>() {
                    @Override
                    public boolean filter(String value) throws Exception {
                        return value.equals(temp1.get(1));
                    }
                }
        ).followedBy("end").where(
                new SimpleCondition<String>() {
                    @Override
                    public boolean filter(String value) throws Exception {
                        return value.equals(temp1.get(2));
                    }
                }
        );

my aim is to give warning with arraylist elements in the map but the order of the arraylist elements is not important because of the stream stream therein.I want to proceed with the remaining elements of this array where I can return the information of this array when I start with any array here. For example:

Incoming data = "l:1","h:1","g:0"
my pattern = "h:1","l:1","g:0" 
Start -> l:1 find
Middle -> g:0 or h:1 | h:1 find
End -> g:0 find -> alarm

Answer 1

so currently AFAIK Flink does not support not ordered patterns out-of-the-box, so basically I see two ways of tackling this issue:

1) You could create all possible patterns that you want to search for and simply union all resulting data streams.

2) As this post suggests FlinkCEP: Can I reference an earlier event to define a subsequent match? You can try to use IterativeCondition that will allow You to access previous elements that were already matched, so basically You would have to define pattern that matches all possible elements from the lists and then simply check in the last condition if all three of them belong to the same list. If so the pattern is found.

Answer 2

 public static  Integer temp1;
    public static  Map<Integer,ArrayList<String>> temp2 = new HashMap<>();     
final Map< Integer,ArrayList<String>> deger = new HashMap<>();
            deger.put(1,new ArrayList<>(Arrays.asList("h:1","g:1","s:0")));
            deger.put(2,new ArrayList<>(Arrays.asList("h:1","g:1","g:0")));
            deger.put(3,new ArrayList<>(Arrays.asList("h:1","c:0","g:0")));
            deger.put(4,new ArrayList<>(Arrays.asList("h:1","s:1","g:0")));


            Pattern<String,?> pattern = Pattern.<String>begin("start").where(
                    new SimpleCondition<String>() {
                        @Override
                        public boolean filter(String value) throws Exception {
                            flag = false;
                            for(Map.Entry<Integer, ArrayList<String>> entryStart : deger.entrySet()) {
                                if(entryStart.getValue().contains(value) && !temp2.containsKey(entryStart.getKey())){
                                        ArrayList<String> newList = new ArrayList<String>();
                                        newList.addAll(entryStart.getValue());
                                        newList.remove(value);
                                        temp2.put(entryStart.getKey(),newList);
                                        flag = true;
                                }
                            }
                            return flag;
                        }
                    }
            ).followedBy("middle").where(
                    new SimpleCondition<String>() {
                        @Override
                        public boolean filter(String middle) throws Exception {
                            flag = false;
                            for(Map.Entry<Integer, ArrayList<String>> entryMiddle : temp2.entrySet()) {
                                if(entryMiddle.getValue().contains(middle) && entryMiddle.getValue().size() == 2){
                                    ArrayList<String> newListMiddle = new ArrayList<String>();
                                    newListMiddle.addAll(entryMiddle.getValue());
                                    newListMiddle.remove(middle);
                                    temp2.put(entryMiddle.getKey(),newListMiddle);
                                    flag = true;
                                }
                            }
                            return flag;
                        }
                    }
            ).followedBy("end").where(
                    new SimpleCondition<String>() {
                        @Override
                        public boolean filter(String end) throws Exception {
                            flag = false;
                            for(Map.Entry<Integer, ArrayList<String>> entryEnd : temp2.entrySet()) {
                                if(entryEnd.getValue().contains(end) && entryEnd.getValue().size() == 1){
                                    flag = true;
                                    temp1 = entryEnd.getKey();
                                }
                            }
                            if (flag)
                                temp2.remove(temp1);
                            return flag;
                        }
                    }
            );

            PatternStream<String> patternStream = CEP.pattern(stream_itemset_ham,pattern);

            DataStream<String> result = patternStream.select(
                    new PatternSelectFunction<String, String>() {
                        @Override
                        public String select(Map<String, List<String>> map) throws Exception {
                            ArrayList<String> NewList= new ArrayList<>();
                            NewList.addAll(deger.get(temp1));
                            String found = "Found";
                            for (String list_element : NewList)
                                found += " " + list_element ;
                            return found;
                        }
                    }
            );
            result.print();

I understand from your question that this kind of solution can be offered.
