How to get the JsonGenerator settings using Jackson in Java?



The JsonGenerator class can be responsible for writing JSON data as a stream instead of constructing an Object Model in memory. The list of settings that can be turned on/off is present in an enum JsonGenerator.Feature, it contains static method values() that returns an array containing the constants of this enum type.

Syntax

public static enum JsonGenerator.Feature extends Enum<JsonGenerator.Feature>

Example

import java.io.*;
import com.fasterxml.jackson.core.*;
public class JsonGeneratorSettingsTest {
   public static void main(String[] args) throws IOException {
      StringWriter writer = new StringWriter();
      JsonFactory jsonFactory = new JsonFactory();
      JsonGenerator jsonGenerator = jsonFactory.createGenerator(writer);
      for(JsonGenerator.Feature feature : JsonGenerator.Feature.values()) {
         boolean result = jsonGenerator.isEnabled(feature);
         System.out.println(feature.name() + ":" + result);
      }
      jsonGenerator.close();
   }
}

Output

AUTO_CLOSE_TARGET:true
AUTO_CLOSE_JSON_CONTENT:true
FLUSH_PASSED_TO_STREAM:true
QUOTE_FIELD_NAMES:true
QUOTE_NON_NUMERIC_NUMBERS:true
ESCAPE_NON_ASCII:false
WRITE_NUMBERS_AS_STRINGS:false
WRITE_BIGDECIMAL_AS_PLAIN:false
STRICT_DUPLICATE_DETECTION:false
IGNORE_UNKNOWN:false
