Examples of javax.json.JsonArrayBuilder

javax.json.JsonArrayBuilder

Builds a {@link JsonArray} from scratch. It uses builder patternto build the array model and the builder methods can be chained while building the JSON array.

For example, for the following JSON array

  [ { "type": "home", "number": "212 555-1234" }, { "type": "fax", "number": "646 555-4567" } ]

a JsonArray instance can be built using:

  JsonArray value = new JsonArrayBuilder() .add(new JsonObjectBuilder() .add("type", "home") .add("number", "212 555-1234")) .add(new JsonObjectBuilder() .add("type", "fax") .add("number", "646 555-4567")) .build();

@see JsonObjectBuilder

              matchedStrs.add(en2.first(), new Pair<Integer, Integer>(en2.second(), en2.third()));
            }


            JsonObjectBuilder senttokens = Json.createObjectBuilder();
            for (Entry<String, Collection<Pair<Integer, Integer>>> sen : matchedStrs.entrySet()) {
              JsonArrayBuilder obj = Json.createArrayBuilder();
              for (Pair<Integer, Integer> sen2 : sen.getValue()) {
                JsonArrayBuilder startend = Json.createArrayBuilder();
                startend.add(sen2.first());
                startend.add(sen2.second());
                obj.add(startend);
              }
              senttokens.add(sen.getKey(), obj);
            }
            pats.add(en.getKey().toStringSimple(), senttokens);
          }
          IOUtils.writeStringToFile(pats.build().toString(), matchedtokensfilename, "utf8");


          // Writing the sentence json file -- tokens for each sentence
          JsonObjectBuilder senttokens = Json.createObjectBuilder();
          for (String sentId : allMatchedSents) {
            JsonArrayBuilder sent = Json.createArrayBuilder();
            for (CoreLabel l : Data.sents.get(sentId)) {
              sent.add(l.word());
            }
            senttokens.add(sentId, sent);
          }
          String sentfilename = constVars.outDir + "/" + constVars.identifier + "/sentences" + ".json";
          IOUtils.writeStringToFile(senttokens.build().toString(), sentfilename, "utf8");
