Class com.fasterxml.jackson.core.JsonGenerator

Examples of com.fasterxml.jackson.core.JsonGenerator.writeTree()

com.fasterxml.jackson.core.JsonGenerator.writeTree()
Method for writing given JSON tree (expressed as a tree where given JsonNode is the root) using this generator. This will generally just call {@link #writeObject} with given node, but is addedfor convenience and to make code more explicit in cases where it deals specifically with trees.

        ObjectMapper op= new ObjectMapper();
        JsonNode p = op.readTree(st);
        Logger.debug("OBJECT:" + p.toString());
        Logger.debug("STRING:" + st);
        //JsonParser jp = jfactory.createJsonParser(st);
        gen.writeTree(p);
      }
      gen.writeEndArray();
      gen.close();
      return sw.toString();
    }catch (Exception e) {
