How to get JsonGenerator's settings using Jackson in Java?

The

JsonGenerator class can be responsible for writing JSON data to the stream instead of building the object model in memory. The list of settings that can be turned on/off exists in the enumeration JsonGenerator.Feature, which contains the static method values( ) , which returns a An array containing constants of this enumeration 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
